Homeopathy is not placebo effect: proof of scientific evidence for homeopathy

Homeopathy has been a medical practice recognized worldwide for more than two centuries, performing care, teaching and research activities in several health institutions and medical schools. It employs a clinical approach based on heterodox and complementary scientific principles (principle of therapeutic similitude, homeopathic pathogenetic experimentation, use of individualized medicines and dynamized or potentiated doses), with the aim of awakening a curative response in the body against its own disorders and/or diseases. Based on different premises from those used by conventional medical practice, homeopathy is often the target of unfounded and widespread criticism from individuals who systematically deny homeopathic assumptions and any scientific evidence that proves them due to their pseudoskeptical and pseudoscientific stance, which prevents a correct and bias-free analysis. In order to enlighten doctors, researchers, health professionals and the general public, demystifying culturally rooted dogmatic positions and the pseudoskeptical fallacies that "there is no scientific evidence for homeopathy" and "homeopathy is placebo effect", the Technical Chamber of Homeopathy of the Regional Council of Medicine of the State of São Paulo (TC-Homeopathy, Cremesp) prepared the "Special Dossier: Scientific Evidence for Homeopathy" in 2017, made available in three independent editions (online in Portuguese and English; printed in Portuguese) in the Revista de Homeopatia (São Paulo). Then, the dossier was published in Spanish in the La Homeopatía de México journal in 2023 in an edition commemorating the journal's 90th anniversary. Encompassing nine narrative reviews on the various lines of homeopathy research and containing hundreds of scientific articles describing experimental and clinical studies, the Dossier highlighted the state of the art of homeopathic science. Proving and expanding this scientific evidence in 13 chapters, the current work aims to update and clarify knowledge in the area. In addition to elucidating the epistemological premises of the homeopathic model in detail, the work describes the various aspects of basic and clinical research which endorse homeopathic practice and treatment in a continuum of information, data and bibliographic references. The work discusses various topics related to research in homeopathy, covering everything from "homeopathic clinical epidemiology" to "pseudoskeptic and pseudoscientific strategies used in attacks on homeopathy", including "pharmacological basis of the principle of similitude", "experimental studies in biological models", "randomized controlled clinical trials", "systematic reviews, meta-analyses and global reports" and "observational studies", among others. In view of the fact that it becomes fruitless and tiring to describe and analyze all the studies and experiments from the different research lines, we suggest and systematize in the different chapters for those who want to delve deeper into the areas of interest, bibliographical surveys of existing literature through the different databases. As we reiterate throughout the work, despite the difficulties and limitations that exist in developing research in homeopathy due to both methodological aspects and the lack of institutional and financial support, the set of experimental and clinical studies described is indisputable proof that "there is scientific evidence for homeopathy" and "homeopathy is not placebo effect", contrary to falsely disseminated prejudice. However, new studies must continue to be developed to improve clinical practice and elucidate peculiar aspects of the homeopathic paradigm. Acting as an integrative and complementary therapy to other specialties, homeopathy can add efficacy, effectiveness, efficiency and safety to medical practice, acting in a curative and preventive manner, reducing symptomatic manifestations and the predisposition to falling ill, with low cost and minimal adverse events, helping doctors to fulfill their "highest and only mission, which is to make sick people healthy, which is called healing" (Samuel Hahnemann, Organon of Medicine, § 1).

El papel del similimum en la homeopatía / The role of Simillimum in homeopathy

Se ha confirmado que la composición química de Similimum en personas sanas es la misma que la de individuos enfermos. Este es el hallazgo más importante en apoyo de una interpretación termodinámica de la homeopatía y se basa en la curación de pacientes con similimum con respecto al equilibrio químico en personas enfermas. La composición química de similimum no es necesaria para un tratamiento en la homeopatía. Todo lo que se requiere es la misma composición química entre las dos moléculas objetivo. Conocer la composición química de las moléculas que causan enfermedades solo es relevante en el caso de buscar un compuesto que pueda actuar como un similimum

It has been confirmed that the chemical composition of Similimum in healthy people is the same as that in diseased individuals. This is the most important finding in support of a thermodynamic interpretation of homeopathy and is based on the healing of patients with Similimum regarding the chemical equilibrium in diseased people. The chemical composition of Simillimum is not required for a treatment in homeopathy. All that is required is the same chemical composition between the two target molecules. Knowing the chemical composition of disease-causing molecules is only relevant in the case of searching for a compound that could act as a Simillimum

Homeopatía: una breve descripción de esta especialidad médica / Homeopathy: a brief description of this medical specialty

La homeopatía es una forma de medicina con 200 años de historia. A lo largo de este tiempo, ha demostrado su capacidad para resolver problemas, a bajo costo, con un amplio alcance y con una aceptación social incuestionable. Según las estimaciones, aproximadamente 500 millones de personas utilizan la homeopatía en todo el mundo, lo que corresponde a alrededor del 7% de la población mundial. Sin embargo, aún existen obstáculos para su integración en la medicina convencional, los cuales deben ser puestos en perspectiva y eliminados. El propósito del presente artículo es contextualizar la homeopatía como una ciencia y un arte tanto en Brasil como en el resto del mundo. Analizamos algunos aspectos relevantes, como el perfil de sus usuarios, las razones para elegir la homeopatía, así como los contextos históricos y sociales para su inclusión en los sistemas educativos y de atención médica. Concluimos que la homeopatía es un sistema medico ético que ofrece un tratamiento sistémico y seguro a los pacientes, con una optima relación costo-beneficio. La homeopatía debe incluirse en las universidades, escuelas de medicina, así como en todos los niveles del sistema de atención médica, asegurando así su naturaleza histórica como especialidad médica.

Homeopathy is a medical approach with 200 years of history. Along this time it demonstrated its ability to solve problems, with low cost, broad scope and unquestionable social acceptance. According to estimates, approximately 500 million people use homeopathy worldwide, corresponding to about 7% of the world population. However, there are still hindrances to its integration into conventional medicine which need to be put into perspective and removed. The aim of the present article is to contextualize homeopathy as a science and an art in Brazil and worldwide. We analyzed some relevant aspects, such as the profile of users, their reasons to choose homeopathy, and historical and social contexts for the inclusion of homeopathy into health care and educational systems. We conclude that homeopathy is an ethical medical system that provides systemic and safe treatment to patients with optimal costbenefit ratio. Homeopathy should be included in universities, schools of medicine and at all levels of the healthcare system, thus ensuring its historical nature as a medical specialty.

La solidez de la investigación homeopática fundamental / The strength of fundamental homeopathic research

La investigación fundamental en homeopatía ha avanzado considerablemente en los últimos 20 años: desde estudios exploratorios con animales y plantas hasta la caracterización de los efectos sistémicos de los medicamentos homeopáticos y estudios in vitro con sistemas celulares aislados para evaluar los cambios en los mecanismos de adaptación celular y señalización intracelular frente a tratamientos homeopáticos variables. El número de artículos publicados a lo largo del tiempo ha permitido realizar varias revisiones sistemáticas. Recientemente, la demostración de que los medicamentos homeopáticos podrían modificar las funciones celulares a través de mecanismos epigenéticos (metilación y desmetilación de ADN) preparó el camino para un campo de investigación completamente nuevo. En paralelo, el descubrimiento de las nanopartículas y propiedades físicas específicas de las diluciones homeopáticas ha arrojado luz hacia un campo antes poco conocido, dado que se consideraba que las diluciones homeopáticas no consistían más que de agua. Así las cosas, los retos para el futuro conciernen a la demostración, o no, de la interrelación entre ambos fenómenos.

Fundamental research in homeopathy has much advanced in the past 20 years. From exploratory studies with animals and plants to the characterization of the systemic effects of homeopathic medicines and in vitro studies with isolated cell systems to assess changes in the mechanisms of cell adaptation and intracellular signaling facing variable homeopathic treatments. The amount of articles published over time enabled several systematic reviews. Recently, demonstration that homeopathic medicines might modify cell functions through epigenetic mechanisms (DNA methylation and demethylation) paved the road for a fully new field of research. In parallel, the discovery of nanoparticles and specific physical properties of homeopathic dilutions brought light to a previously poorly known field, as it was believed that homeopathic dilutions consist in nothing but water. Thus being, challenges for the future concern the demonstration, or not, of the interrelationship between both phenomena.

Efectos de las diluciones homeopáticas altas sobre los modelos in vitro: revisión de la literatura / Effects of high homeopathic dilutions on in vitro models: a review of the literature

Los efectos de las diluciones homeopáticas altas (HD, por sus siglas en inglés) son controvertidos debido a que superan el número de Avogadro. Objetivo: Realizar una revisión de la literatura sobre los efectos de las HD sobre los modelos in vitro. Métodos: Se realizó una búsqueda sistemática en la base de datos PubMed de estudios que evaluaran las HD simples sobre modelos in vitro, publicados de 2007 en adelante. Resultados: 28 publicaciones cumplieron con los criterios de inclusión/exclusión. 26 estudios mostraron efectos evidentes de las HD simples sobre modelos in vitro. La mayor parte de tales estudios fueron realizados en países en donde la homeopatía ha alcanzado un alto nivel de institucionalización. Conclusiones: Los modelos in vitro evidencian de forma clara la actividad biológica de las HD superiores al número de Avogadro y dan cuenta de los efectos encontrados en la práctica clínica. La mayor parte de los estudios fueron realizados en países en donde la homeopatía es reconocida oficialmente, lo cual facilita el acceso a recursos para el desarrollo de la investigación.

the effects of homeopathic high dilutions (HDs) are controversial because they exceed Avogadro's number. Aim: to perform a literature review on the effects of HDs on in vitro models. Methods: a systematic search was performed in database PubMed for studies assessing simple HDs on in vitro models published from 2007 onward. Results: 28 publications met the inclusion/exclusion criteria; 26 studies demonstrated patent effects of simple HDs on in vitro models; most such studies were conducted in countries where homeopathy attained a high level of institutionalization. Conclusions: in vitro models patently evidence biological activity of HDs above Avogadro's number and account for effects found in clinical practice. Most studies were conducted in countries where homeopathy is officially recognized, which facilitates access to resources for the development of research.

¿Los medicamentos homeopáticos provocan agravación o efectos adversos dependientes de los fármacos? / Do homeopathic medicines cause aggravation or drug-dependent adverse effects?

La valoración crítica de la seguridad de los medicamentos homeopáticos se ha desarrollado recientemente. Esta cuestión es relevante para la toma de decisiones de los médicos, pacientes y dependencias regulatorias de fármacos. A pesar de la aparente inverosimilitud de la acción de los medicamentos homeopáticos debido a los procesos farmacotécnicos de la dilución y agitación empleados para su preparación, existen reportes en la literatura médica convencional sobre la toxicidad de los medicamentos homeopáticos, incluyendo eventos que aparentemente ponen en riesgo la vida. Las revisiones sistemáticas de estudios clínicos controlados aleatorizados muestran que los medicamentos homeopáticos provocan más efectos adversos que el placebo, aunque leves y transitorios. El establecimiento de un sistema de monitoreo en línea para la recolección de datos sobre los efectos adversos de los medicamentos homeopáticos, herbolarios o convencionales, es relevante para una evaluación no sesgada de la información reunida a partir de los consumidores y proveedores de atención médica.

Critical appraisal of the safety of homeopathic medicines developed recently. This matter is relevant for decision making by doctors, patients and drug regulatory agencies. Despite the apparent implausibility of the action of homeopathic medicines due to the pharmacotechnical processes of dilution and agitation used for their preparation, there are reports in the conventional medical literature on the toxicity of homeopathic medicines, including apparently life-threatening events. Systematic reviews of randomized controlled trials show that homeopathic medicines cause more adverse effects than placebo, albeit mild and transient. Establishing an online monitoring terapéusystem for collection of data on the adverse effects of homeopathic, herbal or conventional medicines is relevant for non-biased assessment of the information gathered from consumers and health care providers.

Bases científicas del principio de curación homeopática en la farmacología moderna / Scientific bases of the homeopathic healing principle in modern pharmacology

La homeopatía emplea el denominado 'principio de similares' como método terapéutico ­ el cual consiste en administrar medicamentos que provocan ciertos síntomas en individuos sanos para tratar síntomas similares en individuos enfermos (similia similibus curantur) - para inducir una reacción curativa secundaria del cuerpo en contra de sus propios trastornos. Esta reacción secundaria (vital, homeostática o paradójica) del cuerpo se basa en el 'efecto de rebote' de los fármacos modernos, un tipo de evento adverso que se produce después de interrumpir varias clases de fármacos prescritos según el 'principio de los contrarios' (contraria contrariis curantur). Objetivo: La presente revisión ha buscado justificar científicamente el principio de curación homeopática frente a la farmacología clínica y experimental a través de un estudio sistemático del efecto de rebote de los fármacos modernos o reacción paradójica del cuerpo. Métodos: Empleando como referencia estudios y revisiones sobre el tema publicados a partir de 1998, actualizamos los datos añadiendo estudios recientes incluidos en la base de datos PubMed. Resultados: El efecto de rebote se produce después de interrumpir varias clases de fármacos con acción contraria a los síntomas de las enfermedades, exacerbándolos a niveles superiores a aquellos previos al tratamiento. Independientemente de la enfermedad, fármaco, dosis y duración del tratamiento, el fenómeno del rebote se manifiesta en una pequeña proporción de los individuos susceptibles. Siguiendo las premisas homeopáticas, los fármacos modernos también podrían usarse según el principio de la similitud terapéutica, empleando entonces el efecto de rebote (reacción paradójica) con propósito curativo. Conclusiones: Evidenciado por cientos de estudios que constatan la similitud de conceptos y manifestaciones, el efecto de rebote de los fármacos modernos justifica científicamente el principio de la cura homeopática. Aunque el fenómeno de rebote es un evento adverso estudiado por la farmacología moderna, no es conocido por los profesionales de la atención médica, lo cual priva a los médicos de un conocimiento indispensable para el manejo seguro de los fármacos.

Homeopathy employs the so-called 'principle of similars' as therapeutic method - which consists in administering medicines that cause certain symptoms in healthy individuals to treat similar symptoms in sick individuals (similia similibus curantur) - to induce a secondary and healing reaction by the body against its own disorders. This secondary (vital, homeostatic or paradoxical) reaction of the body is based on the 'rebound effect' of modern drugs, a type of adverse event that occurs following discontinuation of several classes of drugs prescribed according to the 'principle of contraries' (contraria contrariis curantur). Aim: The present review sought to scientifically substantiate the homeopathic healing principle vis-à-vis experimental and clinical pharmacology through a systematic study of the rebound effect of modern drugs or paradoxical reaction of the body. Methods: Employing as reference studies and revisions on the subject published since 1998, we updated the data adding recent studies included in database PubMed. Results: The rebound effect occurs after discontinuation of several classes of drugs with action contrary to the symptoms of diseases, exacerbating them to levels above the ones before treatment. Regardless of disease, drug, dose and duration of treatment, the rebound phenomenon manifests in a small proportion of susceptible individuals. Following the homeopathic premises, modern drugs might also be used according to the principle of therapeutic similitude, thus employing the rebound effect (paradoxical reaction) with curative intent. Conclusions: Evidenced by hundreds of studies that attest to the similarity of concepts and manifestations, the rebound effect of modern drugs scientifically substantiates the principle of homeopathic cure. Although the rebound phenomenon is an adverse event studied by modern pharmacology, it is not known by health care professionals, thus depriving doctors of knowledge indispensable for safe management of drugs.

Efectos de las diluciones homeopáticas altas sobre las plantas: revisión de la literatura / Effects of high homeopathic dilutions on plants: a review of the literature

Entre los supuestos no convencionales de la homeopatía, el uso de medicamentos en diluciones altas (HD, por sus siglas en inglés) es una causa de objeciones y escepticismo entre la comunidad científica, formada dentro del paradigma de la dependencia de la dosis de la farmacología clásica. La investigación que busca evidenciar los efectos de las HD homeopáticas recurre a varios modelos experimentales (in vitro, plantas y animales). Objetivo: Describir los resultados de estudios con alta calidad metodológica que han demostrado los efectos positivos de las HD homeopáticas sobre las plantas. Métodos: Tomando como fuente de referencia las revisiones publicadas hasta 2015, actualizamos la información añadiendo datos de estudios recientes incluidos en la base de datos PubMed. Resultados: De los 167 estudios experimentales analizados, 48 cumplieron los criterios mínimos de calidad metodológica, de los cuales 29 detectaron efectos específicos de las diluciones homeopáticas altas sobre las plantas mediante la comparación con controles adecuados. Conclusiones: A pesar de que la mayor parte de los experimentos presentaba una calidad metodológica por debajo del estándar, los estudios que emplearon sistemáticamente reproducibilidad y controles negativos demostraron indiscutibles efectos significativos de las HD homeopáticas sobre las plantas.

Among the non-conventional assumptions of homeopathy, the use of medicines in high dilutions (HD) is a cause for objections and skepticism among the scientific community, trained within the dose-dependency paradigm of classic pharmacology. Research aiming at evidencing the effects of homeopathic HD has resource to several experimental models (in vitro, plants and animals). Aim: To describe the results of studies with high methodological quality that demonstrated positive effects of homeopathic HD on plants. Methods: Taking reviews published until 2015 as reference source, we updated the information through addition of data from recent studies included in database PubMed. Results: From 167 experimental studies analyzed, 48 met the minimum criteria of methodological quality, from which 29 detected specific effects of homeopathic high dilutions on plants through comparison to adequate controls. Conclusions: Despite the substandard methodological quality of most experiments, studies with systematic use of negative controls and reproducibility demonstrated significant indisputable effects of homeopathic HD on plants.

Estudio aleatorizado, doble ciego, sobre la eficacia del tratamiento homeopático en niños con amigdalitis recurrente / Randomized, double-blind study on the efficacy of homeopathic treatment in children with recurrent tonsillitis

La eficacia y seguridad del tratamiento homeopático fueron investigadas en niños con amigdalitis recurrente para la que se indicaba cirugía. Métodos: Estudio clínico prospectivo, aleatorizado, doble ciego, que incluyó 40 niños de entre 3 y 7 años de edad; 20 niños fueron tratados con medicación homeopática y otros 20 niños, con placebo. El seguimiento fue de 4 meses por niño. La evaluación de los resultados fue clínica mediante un cuestionario estándar y examen clínico el primer y último día de tratamiento. La amigdalitis recurrente se definió como ocurrencia de 5 a 7 episodios de amigdalitis bacteriana aguda al año. Resultados: Del grupo de 18 niños que completó el tratamiento homeopático, 14 no presentó episodio alguno de amigdalitis bacteriana aguda; del grupo de 15 niños que recibió placebo, 5 pacientes no presentaron amigdalitis. Esta diferencia fue estadísticamente significativa (p = 0,015). Ninguno de los pacientes presentó efectos secundarios. Conclusiones: El tratamiento homeopático fue efectivo en niños con amigdalitis recurrente, en comparación con el placebo; a 14 niños (78%) ya no se les indicó cirugía. El tratamiento homeopático no se asoció con eventos adversos.

Methods: Prospective, randomized,double-blind clinical trial that included 40 children between ages of 3 to 7 years old;20 children were treated with homeopathic medication and 20 children with placebo. Follow up was 4 months per child. Assessment of results was clinical by means of a standard questionnaire and clinical examination on the first and last day of treatment.Recurrent tonsillitis was defined as 5 to 7 episodes of bacterial acute tonsillitis per year. Results: From the group of 18 children who completed homeopathic treatment, 14 did not present any episode of acute bacterial tonsillitis; from the group of 15 children whoreceived placebo 5 patients did not present tonsillitis; this difference was statistically significant (p= 0,015). None of the patient exhibited side effects. Conclusions: Homeopathic treatment was effective in children with recurrent tonsillitis compared to placebo, 14 children (78%) were no longer indicated surgery. Homeopathic treatment was not associated with adverse events.

Investigación clínica en homeopatía: revisiones sistemáticas y estudios clínicos aleatorizados / Clinical research in homeopathy: systematic reviews and randomized clinical trials

Se considera que las revisiones sistemáticas y estudios clínicos aleatorizados (RCT) presentan el nivel de evidencia más alto. Objetivo: Realizar una revisión descriptiva de las revisiones sistemáticas y estudios clínicos controlados aleatorizados (RCT, por sus siglas en inglés) sobre la efectividad y eficacia de la homeopatía. Métodos: Los datos del reporte publicado por la Liga Medicorum Homeopathica Internationalis (LMHI) en 2014 fueron actualizados mediante una búsqueda en la base de datos PubMed. Resultados: Se localizaron 7 revisiones sistemáticas con meta-análisis, 6 de las cuales concluyeron que los efectos de la homeopatía no son compatibles con el efecto placebo; sólo una revisión sistemática llegó a la conclusión opuesta, aunque fue severamente criticado debido a sus errores metodológicos. Un total de 19 RCT fueron publicados a lo largo del periodo analizado. El 84.2% tuvo por lo menos un resultado positivo. Conclusiones: Con base en las evidencias disponibles del más alto nivel, no es posible afirmar que los efectos de la homeopatía son exclusivamente un efecto placebo. Por el contrario, se han detectado efectos específicos en varios estudios.

Systematic reviews and randomized clinical trials (RCT) are considered to have the highest level of evidence. Aim: To perform a descriptive review of systematic reviews and RCT on the effectiveness and efficacy of homeopathy. Methods: Data from the report published by Liga Medicorum Homeopathica Internationalis (LMHI) in 2014 were updated by means on a search conducted in database PubMed. Results: 7 systematic reviews with meta-analysis were located, 6 of them concluded that the effects of homeopathy are not compatible with placebo effect; only 1 systematic review arrived to the opposite conclusion, but was severely criticized due to methodological flaws. A total of 19 RCT were published along the analyzed period; 84.2% had at least one positive outcome. Conclusions: Based on the available evidences of the highest level it is not possible to assert that the effects of homeopathic are exclusively placebo effect. On the opposite, specific effects were detected in several studies.

Formación médica en la terapéutica no convencional en el mundo (homeopatía y acupuntura) / Medical training in non-conventional therapeutics in the world (homeopathy and acupuncture)

Utilizadas de forma complementaria, alternada o integrada con la medicina convencional, la demanda de la población por las terapias no convencionales se ha incrementado considerablemente en las últimas décadas, requiriendo de los médicos un conocimiento de las nociones básicas de tales enfoques terapéuticos para orientar a sus pacientes en relación con tratamientos distintos a aquellos que suelen prescribir. Entre las mismas, la homeopatía y la acupuntura se han considerado especialidades médicas en Brasil durante varias décadas. Objetivo: Describir el estado actual de la formación médica en terapias no convencionales (homeopatía y acupuntura) alrededor del mundo. Métodos: Actualizamos los datos relacionados con los estudios y revisiones publicados hasta 2013 a través de una revisión de los estudios más recientes incluidos en la base de datos PubMed. Resultados: En todos los países, la enseñanza de terapias no convencionales se considera un tema relevante para la formación de médicos como una función del creciente interés de la población en su uso, con un amplia variedad de enfoques dirigidos a los estudiantes de licenciatura y posgrado, médicos residentes y profesionales con otras especialidades médicas. Conclusiones: Las escuelas brasileñas de medicina deben proporcionar a los estudiantes de licenciatura y posgrado, así como a los médicos residentes, un conocimiento preciso de los supuestos teóricos y enfoques clínico-terapéuticos propios de la homeopatía y la acupuntura, entre otras terapias no convencionales.

Used as complementary to, alternating or integrated with mainstream medicine, the population's demand for non-conventional therapies has substantially increased in the past decades, requiring from doctors knowledge on the basic notions of such therapeutics to orient their patients regarding treatments different to the ones they usually prescribe. Among them, homeopathy and acupuncture are considered medical specialties in Brazil for various decades. Aim: To describe the current state of medical education in non-conventional therapies (homeopathy and acupuncture) around the world. Methods: We updated data resulting from studies and reviews published until 2013 through a review of more recent studies included in database PubMed. Results: In all countries the teaching of non-conventional therapies is considered a relevant topic for the training of doctors as a function of the increasing interest of the population in their use, with a broad range of approaches targeting undergraduate and graduate students, medical residents and doctors from other medical specialties. Conclusions: The Brazilian medical schools must provide undergraduate and graduate students and medical residents accurate knowledge on the theoretical assumptions and clinical-therapeutic approaches proper to homeopathy and acupuncture, among other non-conventional therapies.

Estrógeno potenciado en el tratamiento homeopático del dolor pélvico asociado a endometriosis: un estudio aleatorizado, doble ciego, controlado con placebo, de 24 semanas / Potentiated estrogen in the homeopathic treatment of pelvic pain associated with endometriosis: a 24-week randomized, double-blind, placebo-controlled study

Evaluar la eficacia y seguridad del estrógeno potenciado en comparación con el placebo en el tratamiento homeopático del dolor pélvico asociado a endometriosis (EAPP, por sus siglas en inglés). Diseño del estudio: El presente fue un estudio clínico aleatorizado, doble ciego, controlado con placebo, de 24 semanas, el cual incluyó a 50 mujeres de entre 18 y 45 años de edad con diagnóstico de endometriosis infiltrante profunda con base en ultrasonido transvaginal o imágenes de resonancia magnética después de preparación intestinal, así como puntaje ≥ 5 en una escala visual analógica (VAS: rango de 0 a 10 puntos) para el dolor pélvico asociado con la endometriosis. Se administró estrógeno potenciado (12cH, 18cH y 24cH) o placebo dos veces al día por vía oral. La medida principal de resultado fue el cambio en la severidad de los puntajes parcial y global de EAPP (VAS) de la línea basal a la semana 24, determinada como la diferencia en el puntaje medio de cinco modalidades de dolor pélvico crónico (dismenorrea, dispareunia profunda, dolor pélvico no cíclico, dolor intestinal cíclico y/o dolor urinario cíclico). Las medidas secundarias de resultado fueron la diferencia media de puntaje para la calidad de vida evaluada con el Cuestionario de Salud SF-36, los síntomas de depresión en el Inventario de la Depresión de Beck (BDI) y los síntomas de ansiedad en el Inventario de Ansiedad de Beck (BAI). Resultados: El puntaje global de EAPP (VAS: rango de 0 a 50 puntos) se redujo en 12.82 (p < 0.001) en el grupo tratado con estrógeno potenciado de la línea basal a la semana 24. El grupo que utilizó estrógeno potenciado también presentó una reducción en el puntaje parcial (VAS: rango de 0 a 10 puntos) en tres modalidades de EAPP: dismenorrea (3.28; p < 0.001), dolor pélvico no cíclico (2.71; p = 0.009) y dolor intestinal cíclico (3.40; p < 0.001). El grupo de placebo no mostró cambio significativo alguno en los puntajes global o parcial de EAPP. Además, el grupo de estrógeno potenciado mostró un mejoramiento significativo en tres de ocho ámbitos de SF-36 (dolor de cuerpo, vitalidad y salud mental) y síntomas de depresión (BDI). El grupo de placebo no mostró un mejoramiento significativo a este respecto. Estos resultados demuestran la superioridad del estrógeno potenciado sobre el placebo. Se asociaron pocos eventos adversos con el estrógeno potenciado. Conclusiones: El estrógeno potenciado (12cH, 18cH y 24cH) en dosis de 3 gotas dos veces al día durante 24 semanas fue significativamente más efectivo que el placebo para reducir el dolor pélvico asociado con la endometriosis. Registro del estudio clínico: ClinicalTrials.gov Identificador: https://clinicaltrials.gov/show/NCT02427386.

To evaluate the efficacy and safety of potentized estrogen compared to placebo in homeopathic treatment of endometriosis-associated pelvic pain (EAPP). Study design: The present was a 24-week, randomized, doubleblind, placebocontrolled trial that included 50 women aged 18-45 years old with diagnosis of deeply infiltrating endometriosis based on magnetic resonance imaging or transvaginal ultrasound after bowel preparation, and score ≥ 5 on a visual analogue scale (VAS: range 0 to 10 points) for endometriosis-associated pelvic pain. Potentized estrogen (12cH, 18cH and 24cH) or placebo was administered twice daily per oral route. The primary outcome measure was change in the severity of EAPP global and partial scores (VAS) from baseline to week 24, determined as the difference in the mean score of five modalities of chronic pelvic pain (dysmenorrhea, deep dyspareunia, non-cyclic pelvic pain, cyclic bowel pain and/or cyclic urinary pain). The secondary outcome measures were mean score difference for quality of life assessed with SF-36 Health Survey Questionnaire, depression symptoms on Beck Depression Inventory (BDI), and anxiety symptoms on Beck Anxiety Inventory (BAI). Results: The EAPP global score (VAS: range 0 to 50 points) decreased by 12.82 (p < 0.001) in the group treated with potentized estrogen from baseline to week 24. Group that used potentized estrogen also exhibited partial score (VAS: range 0 to 10 points) reduction in three EAPP modalities: dysmenorrhea (3.28; p < 0.001), non-cyclic pelvic pain (2.71; p = 0.009), and cyclic bowel pain (3.40; p < 0.001). Placebo group did not show any significant changes in EAPP global or partial scores. In addition, the potentized estrogen group showed significant improvement in three of eight SF-36 domains (bodily pain, vitality and mental health) and depression symptoms (BDI). Placebo group showed no significant improvement in this regard. These results demonstrate superiority of potentized estrogen over placebo. Few adverse events were associated with potentized estrogen. Conclusions: Potentized estrogen (12cH, 18cH and 24cH) at a dose of 3 drops twice daily for 24 weeks was significantly more effective than placebo for reducing endometriosis-associated pelvic pain.

Ensaios clínicos de pacientes únicos em homeopatia: aspectos técnicos, educacionais e éticos / Single-case studies in homeopathy: technical, educational and ethical aspects

ensaio clínico de pacientes únicos (ECPU/ensaio n-de-1) consiste na observação sistemática de condutas terapêuticas adotadas para otimizar o restabelecimento da saúde em um único paciente, com múltiplos cruzamentos ao longo do tratamento, podendo ter adicionalmente propósito de pesquisa clínica. Foi proposto há décadas e tem sido mais utilizado nas áreas de psicologia clínica, recebendo maior atenção em estudos médicos nos últimos anos. Embora seja considerado como o tipo de estudo com maior força para tomada de decisões terapêuticas, ainda são escassas as publicações sobre o seu emprego em medicina. Este artigo aborda as possibilidades dos ECPUs na avaliação dos resultados clínicos da homeopatia, explorando seus aspectos metodológicos, éticos e educacionais característicos em comparação aos ensaios clínicos randomizados tradicionais. Em pesquisa clínica, diferentemente dos ensaios convencionais, os ECPUs permitem a participação mais direta do paciente na escolha dos procedimentos e acompanhamento dos resultados, com possibilidade de alterações imediatas e sem que seja necessária sua exclusão do estudo, além de implicações de ordem econômica, política e ética. Podem ser utilizados no teste de medicamentos usados de modo off label, sem as restrições impostas à inclusão de pacientes vulneráveis nos estudos clínicos habituais, com excessiva artificialização no delineamento experimental. Poderiam ser ainda adotados nas diversas fases de teste clínico dos medicamentos, reduzindo a exposição de grande número de participantes aos riscos da pesquisa e baixa margem de extrapolação clínica dos resultados ao conjunto da população. Em homeopatia, podem ajudar a aprimorar o conhecimento dos medicamentos já em uso ou a melhor detectar os efeitos de novas substâncias testadas em ensaios patogenéticos homeopáticos. Em função do seu propósito principal de otimização do tratamento individual ­ e do alinhamento com os princípios éticos da autonomia e beneficência associados à prática da medicina centrada-no-paciente ou de precisão - podem ser desenvolvidos em conjunto com o paciente e familiares, sem a obrigatoriedade de aprovação prévia por Comissões de Ética Médica ou Comitês de Ética em Pesquisa.

The single-patient clinical trial (n-of-1 trial) is primarily designed to systematically observe outcomes from different therapeutic options to optimize the restoration of health in a single patient, with multiple crossovers throughout the treatment. They may additionally have a clinical research purpose. They have been proposed for decades and were mostly used in clinical psychology, receiving greater attention in medical studies in recent years. Although it is considered the type of study with the greatest strength for therapeutic decision-making, there are still few publications with its application in medicine. This article discusses the possibilities of single-patient clinical trials in assessing homeopathy outcomes, exploring their characteristic methodological, educational and ethical aspects compared to traditional randomized clinical trials. In clinical research, unlike conventional trials, single-patient clinical trials allow for more direct patient participation in choosing procedures and monitoring results, with the possibility of immediate changes without the need for their exclusion from the study, in addition to economic, political and ethical implications. They can be used in testing off-label drugs without the restrictions imposed on the inclusion of vulnerable patients in usual clinical studies, with excessive artificiality in the experimental design. They could also be adopted in the various clinical trial phases of drugs, reducing the exposure of many participants to the risks of research and low margin of clinical extrapolation of the results to the entire population. In homeopathy, they can help refine the knowledge of medications already in use or better detect the effects of new substances tested in homeopathic pathogenetic trials. Due to their purpose of optimizing individual treatment ­ and alignment with the principles of patient-centered or precision medicine ­ they can be developed jointly with the patient and her family without the mandatory prior approval by Medical Ethics Committees or Research Ethics Committees.

Hahnemann: retrospectivo e prospectivo. É uma atualidade possível? / Retrospective and prospective. Is this a possible update?

Ater-se ao objeto médico para atender a demanda de uma clínica mais eficiente, a saber, com a finalidade específica de curar ou controlar patologias definidas é um antigo problema da medicina. Aqui tentamos apontar as mudanças que Hahnemann propôs, incluindo, mas para além do uso do princípio dos semelhantes e das doses infinitesimais. Em sua ética, o radical compromisso com o outro não significa estar somente atento às modificações de caráter patológico como primazia da atenção médica. A originalidade aqui foi ter pretendido definir-se por um humanismo ético, cujos principais atributos devem ser a solidariedade e a compreensão do sujeito que sofre. Sofrimentos manifestos através das moléstias agudas e crônicas, idiossincrasias imaginárias ou reais que o sujeito enfermo narra ao médico, buscando alívio e suporte. A ajuda homeopática não vem (ou não poderia vir) só de encontro aos corpos enfermos, ela virá sempre como um atendimento das sensações, metáforas e alusões que invadem e assolam o sujeito.Ao mesmo tempo é preciso que os praticantes abandonem valorizem e preservem as muitas contribuições que resistiram ao tempo, mas ao mesmo tempo evitem o culto à personalidade ­ aspecto que até aqui tem sido refratário às críticas. Para preservar o legado de Hahnemann é preciso conservar a atitude crítica sem render-se aos grandes modismos e efemérides metodológicas que trazem mais danos do que benefícios. Como antecipou Constantine Hering, a homeopatia não pode perder seu eixo empírico, sob o risco de ser no futuro compreendida e reduzida a uma caricatura na história da medicina. Por isso é importante que se mantenha como um sistema científico aberto e obedeça às premissas do experimental enquanto mantém o foco em um programa de pesquisas tanto consistente como abrangente.

Sticking to the medical object to meet the demand for a more efficient clinic, namely, with the specific purpose of curing or controlling defined pathologies, is an old problem in medicine. Here we try to point out the changes that Hahnemann proposed, including, but beyond the use of the principle of similars and infinitesimal doses. In his ethics, the radical commitment to others does not mean only being attentive to changes of a pathological nature as the priority of medical care. The originality here was to have intended to be defined by an ethical humanism, whose main attributes must be solidarity and understanding of the subject who suffers. Suffering manifested through acute and chronic illnesses, imaginary or real idiosyncrasies that the sick subject narrates to the doctor, seeking relief and support. Homeopathic help does not come (or could not come) only against sick bodies, it will always come as a response to the sensations, metaphors and allusions that invade and plague the subject. At the same time, it is necessary for practitioners to abandon, value and preserve the many contributions that have stood the test of time, but at the same time avoid the cult of personality ­ an aspect that has so far been refractory to criticism. To preserve Hahnemann's legacy, it is necessary to maintain a critical attitude without surrendering to great fads and methodological ephemerides that bring more harm than good. As Constantine Hering anticipated, homeopathy cannot lose its empirical axis, at the risk of being misunderstood in the future and reduced to a caricature in the history of medicine. Therefore, it is important that it remains an open scientific system and obeys experimental premises while maintaining focus on a consistent and comprehensive research

Princípios de Hahnemann no tratamento de um quadro agudo: relato de caso / Hahnemann's principles in the treatment of a acute frame: case report

A Homeopatia é uma ciência fundamentada na observação dos fenômenos naturais. Segundo Hahnemann, a cura homeopática é aquela que acontece de acordo com as leis naturais, sendo uma delas a lei dos semelhantes, já descrita por muitos médicos desde a antiguidade, inclusive Hipócrates. Quando são seguidos os princípios estipulados por Hahnemann, considerando a totalidade sintomática, incluindo a escolha do medicamento, sua potência, dose e frequência de administração, o tratamento homeopático torna-se eficaz tanto em casos crônicos quanto nos agudos, "sendo capaz de aniquilar a doença sem produzir novos e sérios distúrbios". Este estudo tem como objetivo exemplificar como, seguindo os princípios estipulados, a Homeopatia pode ser eficaz no tratamento de um quadro agudo que não obteve sucesso com a terapêutica alopática convencional. Trata-se de um relato de caso de paciente de 64 anos, sem doença prévia instalada, com ferimento corto- -contuso em mão esquerda após queda da própria altura, mantendo sinais flogísticos e ausência de cicatrização 13 dias após a realização da sutura e de fazer uso regular de antibiótico e anti-inflamatório prescritos. Após a avaliação da totalidade sintomática, foi prescrito Belladonna 6cH, administrada pelo método plus, resultando em alívio imediato dos sintomas e cura total em 5 dias. Realizando com cautela o diagnóstico homeopático e a partir disso elegendo o medicamento mais similar ao caso, com potência, dose e frequência de administração adequadas, é possível obter resultados eficazes com o tratamento homeopático, sempre considerando a constituição do indivíduo.

Homeopathy is a science based on the observation of phenomena natural. According to Hahnemann, homeopathic cure is one that happens according to natural laws, one of which is the law of similars, already described by many doctors since ancient times, including Hippocrates. When the principles stipulated by Hahnemann, considering the symptomatic totality, including the choice of the medicine, its potency, dose and frequency of administration, the Homeopathic treatment becomes effective in both chronic and in acute cases, "being capable of annihilating the disease without producing new and serious disturbances." This study aims to exemplify how, following the stipulated principles, Homeopathy can be effective in treatment of an acute condition that has not been successful with therapy conventional allopathic. This is a patient case report 64 years old, with no previous illness, with a cut wound-bruise in the left hand after falling from a height, maintaining phlogistic signs and lack of healing 13 days after the procedure suture and regular use of prescribed antibiotics and anti-inflammatory drugs. After evaluating the totality of symptoms, Belladonna was prescribed 6cH, administered by the plus method, resulting in immediate relief of symptoms and complete cure in 5 days. Carrying out the diagnosis with caution homeopathic and from there choosing the medicine most similar to the case, with adequate potency, dose and frequency of administration, it is possible to obtain effective results with homeopathic treatment, always considering the constitution of the individual.

Homeopatia na oncologia pediátrica: é possível? Uma série de casos / Homeopathy in oncology pediatric: is it possible? case series

A Homeopatia é uma das ciências médicas complementares mais utilizadas para pacientes com Câncer, sendo também utilizada durante o tratamento de crianças com a referida moléstia, havendo relato e debate de seu uso na literatura médica. Visando construir o conhecimento e dividir experiências, relatamos seis casos de crianças e adolescentes com câncer, para os quais realizamos tratamento homeopático, em nossa experiência na cidade de São Paulo. Além da diversidade de sexos e idade, os casos apresentam diagnósticos oncológicos diferentes, bem como momentos diferentes no tratamento, sendo curativo ou paliativo, e os medicamentos homeopáticos, baseados tanto na totalidade sintomática característica quanto no modo reacional para cada indivíduo, puderam ser utilizados para todos com satisfação de famílias e pacientes, mesmo quando o desfecho letal foi a via final no estado paliativo. Assim, a Homeopatia pode também ser prescrita para os casos oncológicos infantis como terapia complementar ao tratamento convencional, sendo a pesquisa neste campo vasta e possível.

Homeopathy is one of the most used complementary medical sciences for cancer patients, and is also used duringtreatment of children with the aforementioned disease, with reports and debate of its use in medical literature. Aiming to build knowledge and sharing experiences, we report six cases of children and adolescents with cancer, for which we carry out homeopathic treatment, in our experience in the city of São Paulo. In addition to the diversity of sexes and age, the cases present different oncological diagnoses, as well as as different moments in the treatment, being curative or palliative, and homeopathic medicines, based both on symptomatic totality characteristic and in the reactional mode for each individual, could be used for everyone with the satisfaction of families and patients, even when the lethal outcome was the final route in the palliative state. Therefore, Homeopathy can also be prescribed for oncological cases children as complementary therapy to conventional treatment, research in this field is vast and possible.

Ética em homeopatia / Ethics in homeopathy

A homeopatia é uma área especializada do conhecimento médico, praticada entre nós há quase dois séculos, que tem sido progressivamente exposta e pesquisada nos meios acadêmicos. O Brasil é um dos maiores produtores do conhecimento médico-científico, ocupando posição de destaque no cenário mundial a publicação de artigos técnicos em homeopatia por cientistas brasileiros. Tal fato pode ser decorrência do seu reconhecimento como especialidade médica pelo Conselho Federal de Medicina, em 1980, com criação de movimentos internos para sua difusão e investigação em escolas médicas e ambientes acadêmicos. A homeopatia é uma área distinta na terapêutica médica que se vale de medicamentos preparados conforme farmacotécnica própria, oficialmente aprovada, e aplicados segundo um princípio de cura enunciado há mais de dois mil anos por Hipócrates. De acordo com o relatório Demografia Médica no Brasil (2023), a homeopatia ocupa o 33º lugar em número de especialistas, entre as 55 especialidades, contando com 2.973 médicos certificados. A este número, devem ser acrescidos outros médicos que conhecem e utilizam a homeopatia em suas outras especialidades, pois boa parte dos médicos especialistas em homeopatia também têm outra especialidade paralela: 31% são qualificados em Pediatria, 20% em Clínica Médica, 12% em Acupuntura e 9% em Medicina de Família e Comunidade, entre outras. Esta obra é fruto de um trabalho coletivo da Câmara Técnica de Homeopatia do CREMESP, que durante um ano se dedicou à sua elaboração, com discussão dos tópicos e prévia revisão conjunta dos textos elaborados por membros da Câmara Técnica ou convidados. É oportuna e de utilidade pública a sua divulgação para todos os médicos que ainda não a conhecem, pois dialoga, em diversas passagens, com as necessidades e expectativas dos profissionais médicos, independentemente de sua área de especialização ou de atuação.

Tratamento homeopatico na asma bronquica: relato de caso / Homeopathic treatment in bronchial asthma: case report

A Asma Brônquica é uma patologia de elevada prevalência e mortalidade, definida como uma doença inflamatória cronica das vias aéreas, caracterizada pela presença de broncoespasmo, inflamação da mucosa brônquica e hipersecreção brônquica decorrentes de hiper-reatividade pulmonar a diversos fatores. Clinicamente manifesta-se por episódios recorrentes de sibilância, dispneia e aperto no peito e tosse, ocorrendo mais pelo período noturno e manha. O tratamento é dividido em duas fases: tratamento do episódio agudo e tratamento de manutenção. Foi realizado um relato de caso no qual após uma anamnese detalhada na busca da individualização da paciente e da repertoriarão dos sintomas foi prescrito o medicamento homeopático Pulsatilla, associado ao tratamento convencional da asma. Observou-se uma melhora significativa do quadro clínico da paciente. Este relato de caso ressalta como a Homeopatia como proposta terapêutica coadjuvante pode contribuir para a diminuição das crises asmáticas recorrentes, assim como diminuir ou a retirada mais precoce das medicações de controle com melhora na qualidade de vida dos pacientes portadores de asma.

Bronchial Asthma is a pathology of high prevalence and mortality, defined as a chronic inflammatory disease of the airways, characterized by the presence of bronchospasm, inflammation of the bronchial mucosa and bronchial hypersecretion resulting from pulmonary hyperreactivity to various factors. Clinically it is manifested by recurrent episodes of wheezing, dyspnea and chest tightness and coughing, occurring more at night and in the morning. Treatment is divided into two phases: treatment of the acute episode and maintenance treatment. A case report was carried out in which, after a detailed anamnesis in the search for the individualization of the patient and the repertoire of the symptoms, the homeopathic medicine Pulsatilla was prescribed, associated with the conventional treatment of asthma. There was a significant improvement in the patient's clinical status. This case report highlights how Homeopathy as an adjuvant therapeutic proposal can contribute to the reduction of recurrent asthmatic crises, as well as the reduction or earlier withdrawal of control medications with an improvement in the quality of life of patients with asthma.
