Understanding Why Homeopathic Medicines are Used for Menopause: Searching for Insights into Neuroendocrine Features.

BACKGROUND: Menopause is a physiological event that marks the end of a woman's reproductive stage in life. Vasomotor symptoms and changes in mood are among its most important effects. Homeopathy has been used for many years in treating menopausal complaints, though clinical and pre-clinical research in this field is limited. Homeopathy often bases its prescription on neuropsychiatric symptoms, but it is unknown if homeopathic medicines (HMs) exert a neuroendocrine effect that causes an improvement in vasomotor symptoms and mood during menopause. OBJECTIVES: The study's objectives were to address the pathophysiological changes of menopause that could help in the understanding of the possible effect of HMs at a neuroendocrine level, to review the current evidence for two of the most frequently prescribed HMs for menopause (Lachesis mutus and Sepia officinalis), and to discuss the future directions of research in this field. METHODS: An extensive literature search for the pathophysiologic events of menopause and depression, as well as for the current evidence for HMs in menopause and depression, was performed. RESULTS: Neuroendocrine changes are involved in the pathophysiology of vasomotor symptoms and changes in mood during menopause. Gonadal hormones modulate neurotransmitter systems. Both play a role in mood disorders and temperature regulation. It has been demonstrated that Gelsemium sempervirens, Ignatia amara and Chamomilla matricaria exert anxiolytic effects in rodent models. Lachesis mutus and Sepia officinalis are frequently prescribed for important neuropsychiatric and vasomotor symptoms. Dopamine, a neurotransmitter involved in mood, is among the constituents of the ink of the common cuttlefish, Sepia officinalis. CONCLUSION: Based on all the pathophysiologic events of menopause and the improvement in menopausal complaints that certain HMs show in daily practice, these medicines might have a direct or indirect neuroendocrine effect in the body, possibly triggered via an as-yet unidentified biological mechanism. Many unanswered questions in this field require further pre-clinical and clinical research.

Impact of a Novel Homeopathic Complex Medicine on the Management of Multiple Antibiotic-Resistant Bovine Mastitis: An Open-Label, Non-Randomized, Placebo-Controlled Trial.

BACKGROUND: Bovine mastitis is characterized by an inflammatory process in the mammary gland and represents one of the main diseases affecting a dairy herd. Management of mastitis is most commonly via antibiotics, but the rising incidence of multiple antibiotic resistance (MAR) means that additional options are needed. Homeopathic products can be administered in dairy farming for a range of clinical reasons and may be preferential due to the absence of residues. OBJECTIVES: The aim of this study was to assess the potential of a novel homeopathic complex medicine in managing bovine mastitis. METHODS: Twenty-four lactating Holstein cows with mastitis were divided into two groups: the homeopathic complex group received a homeopathic complex daily for 60 days at a dose of 20 g/d; the placebo group received the calcium carbonate vehicle without homeopathic medicines at the same dose and repetition. The main outcome measure was somatic cell count (SCC; cells/mL), with additional outcome measures including milk production (kg/d), milk constituents (percentage of protein, fat, lactose and total milk solids), and serum levels of cortisol, glucose, ammonia and lactic acid. All outcomes were measured at the beginning of the study and after 30 and 60 days. Milk samples were also collected from all animals at the beginning of the study, confirming a high (>0.2) MAR index for isolated bacterial cultures. RESULTS: Assessment of SCC showed a statistically significant difference favoring the homeopathic complex versus placebo group at day 60. A reduction in serum cortisol levels and an increase in fat, lactose and total milk solids in animals treated with the homeopathic complex at day 60 were also seen. Other outcome measures did not show statistically significant inter-group differences. CONCLUSION: The results of this non-randomized, open-label, placebo-controlled trial suggest the potential for a novel homeopathic complex medicine in management of multiple antibiotic-resistant bovine mastitis, thus offering dairy farmers an additional option to antibiotics and making dairy products safer for consumer health and milk production more sustainable.

Tratamento homeopático na infertilidade feminina: relato de caso / Homeopathic treatment in female infertility: case report

A infertilidade afeta milhões de mulheres em todo o mundo, sendo quase metade dos casos decorrentes de fatores tuboperitoneal, destacando- se a endometriose como doença de grande prevalência. Este artigo apresenta um caso clínico bem-sucedido de tratamento homeopático para infertilidade, resultando em rápida desobstrução da tuba uterina e gravidez em um ciclo ovulatório. O tratamento incluiu simillium (Nux vomica) e constitucional (Calcarea phosphorica), além de medicamento episódico (Eupion, Borax veneta e Endometrium).

Infertility affects millions of women worldwide, with nearly half of the cases attributed to tuboperitoneal factors, with endometriosis being a prevalent condition. This article presents a successful clinical case of homeopathic treatment for infertility, resulting in rapid unblocking of the fallopian tube and pregnancy in one ovulatory cycle. The treatment included simillium (Nux vomica) and constitutional (Calcarea phosphorica) remedies, along with episodic medication (Eupion, Borax veneta and Endometrium).

Use of homeopathic products in pigs feed improves the percentage, quality and marbling of meat.

Studies and innovations on alternative feed additives, especially on homeopathic remedies have been highlighted in order to replace or reduce the use of antibiotics in pig production. This paper aimed to assess the addition of homeopathic products in pig diet and their effects on the growth performance, serum metabolites, nutrient and energy digestibility, carcass traits and meat quality. A total of 60 immunocastrated male pigs, weighing on average 30.91 ± 0.95 kg, were distributed in two treatments, 10 replicates and three animals/experimental unit. There was no effect (P≥0.05) of treatment on the growth performance and serum metabolites. The percentage of acid-insoluble ash recovered in the diet was greater (P≤0.01) in diets containing homeopathic products. The apparent digestible energy of diets containing homeopathic products was reduced (P≤0.01) in the growing phase and reduced (P≤0.01) the apparent digestibility coefficients of dry matter, crude protein, soluble neutral and acid detergent fibers, and gross energy in the growing and finishing phases. Pig that received diets with homeopathic products had higher (P≤0.05) amount of meat, percentage of meat and marbling. The use of homeopathic products in diets improves the percentage and quality of meat, as well as the marbling of the pig carcass, maintaining the performance.

Homeopathic Treatment in Patients with COVID-19: Analysis of Clinical Evolution and Comparison between Cases in 2020 and 2021.

BACKGROUND: The manifestations of coronavirus disease 2019 (COVID-19) can result in several prognoses and lead patients to look for appropriate complementary or alternative treatment options according to their personal situation and available health care. Patients with mild symptoms or those who have not yet reached the maximum severity of their condition are those who seek outpatient care, where homeopathic treatment might be considered, given the well documented history of this medical system in several epidemics in the past. OBJECTIVE: The aim of this study was to compare the homeopathic treatment used for symptomatic cases of COVID-19 in March and April 2020 with cases treated in March and April 2021. METHOD: This is a retrospective observational study based on the analysis of the medical records of symptomatic COVID-19 patients treated on an outpatient basis with homeopathy at the Hahnemanniano George Galvão Institute in São Paulo, Brazil. We analyzed 54 cases, divided into two samples (27 cases in each year), similar in relation to age, gender and origin of the patients. RESULTS: The development was distinct in the 2 years, with improvement of symptoms after 3 days of the first homeopathic prescription in 2020 whilst in 2021 the improvement occurred from the sixth day onward. The most frequently prescribed homeopathic medicine also differed in the two samples (Antimonium tartaricum in 2020; Arsenicum album in 2021), which indicates the different disease characteristics at these two moments of the epidemic. CONCLUSION: In 2020, the symptomatology of the cases was mainly acute and the main medicine was Antimonium tartaricum. By comparison, in 2021 a greater interference from individuals' previous chronic miasmatic disease may explain the change in the main medicines used that year, with Arsenicum album being the most prescribed in the cases studied.

The Materiality of Homeopathic Medicines. DynHom Research Program

Homeopathy is controversial because using highly dilute medicines (high homeopathic potencies, HHP) beyond the Avogadro/Loschmidt limit. Previous publications [1,2] using NMR relaxation revealed the involvement of nanobubbles and/or nanoparticles and/or nanometric superstructures in high potentizations. Nano Tracking Analyse (NTA) demonstrated the presence of particles in HHPs [3,4]. WithSEM-EDX [5] we observed an ionic diversity common to all preparations including HHPs and significant differences in the relative quantity of each ion between different homeopathic manufacturing lines and controls. FTIR spectroscopy [6] shows that the molecular composition is that of carbonates, primarily sodium bicarbonate.Methods:To observe the materiality of homeopathic medicines a multidisciplinary approach is necessary. In collaboration with several universities,we canobserve these medications with NMR, NTA, SEM-EDX, FTIR, pH,and EPA. Results:The essential component of all already studied homeopathic medicines is sodium hydrogen carbonate modulated by some other elements in a specific quantity, size,and shape. The probability that the observed results could have occurred just by random chance can be rejected(significantlyabove the Avogadro limit) p < 0,001.Conclusions:The homeopathic medicines do contain material with a specific ionic composition even in HHPs diluted beyond the Avogadro/Loschmidt limit. This specificity can be attributed to the manufacturing process. These results demonstrate that the step-by-step process (dynamized or not) does not match the theoretical expectations in a dilution process. The starting material and dilution/dynamization method influencethe nature of these NPs. The role of carbonates and sodium bicarbonate must be carefully studied in the future. Its aqueous solution is alkaline in nature but itis an amphoteric compound, which means that the compound has both acidic as well as alkaline character. The reaction with acids results in sodium salts and carbonic acid and the reaction with the basic solution producescarbonates and water. Specific electric fields are indeed detectable.

Effect of Ointments of Sulphur or Pyrogenium on Larvae of Cochliomyia hominivorax (Diptera: Calliphoridae).

BACKGROUND: Myiasis by Cochliomyia hominivorax (Diptera: Calliphoridae) is a serious problem in animal health in tropical and sub-tropical regions. Ointment-type preparations are a good option of formulation in cases of myiasis in farm and pet animals. Sulphur and Pyrogenium have already shown in-vitro efficacy on C. hominivorax. This article describes an in-vitro experiment to test the inhibition of development from exposing larvae of C. hominivorax to two homeopathic ointments (prepared individually with Sulphur or Pyrogenium). METHODS: The homeopathic ointments were produced by mixing sterile lanolin, tocopherol and homeopathic medicine on a hydroalcoholic basis according to the Brazilian Homeopathic Pharmacopoeia. Larvae were obtained from naturally occurring myiases in sheep (wild larvae) or from a laboratory colony. The test consisted of exposing a group of 10 third-stage C. hominivorax wild larvae in contact with Sulphur or Pyrogenium ointment, or a group of 15 laboratory-propagated larvae in contact with the alcoholic vehicle of the ointment or homeopathic medicines prepared in sterile water (Sulphur or Pyrogenium), and observing the effect on the development, longevity and fertility of the blow-fly specimens. RESULTS: The C. hominivorax larval inhibition rate was 90.0% for the Sulphur ointment group and was 86.0% for the Pyrogenium ointment group. The non-alcoholic vehicle and the alcoholic vehicle inhibited the development of 24.0% and 22.08% of the larvae respectively. Sulphur prepared in sterile water inhibited the development of 74.67% and Pyrogenium in sterile water inhibited 73.33% of larvae. Specimens that survived contact with homeopathic ointments had their longevity decreased and did not reproduce. CONCLUSION: Ointments of Sulphur or Pyrogenium were able to inhibit the development of C. hominivorax larvae. The ointment vehicle was harmless.

Homeopathy for COVID-19 Prevention: Report of an Intervention at a Brazilian Service Sector Company.

BACKGROUND: COVID-19 quickly became a serious public health problem worldwide, with serious economic and social repercussions. Homeopaths around the world have been studying to find a genus epidemicus (GE) medicine that might help in the prevention and treatment of this disease. OBJECTIVE: To compare the incidence of COVID-19 between employees who received or did not receive a homeopathic GE medicine for disease prevention. METHODS: Retrospective cohort analysis. The study population comprised all employees of a service sector company in São Paulo, Brazil, and followed up by the corporate Occupational Health department. Intervention consisted of administering Arsenicum album 30cH in a one-weekly dose. Primary outcome was incidence of COVID-19 during 3-months' follow-up (April to July, 2020). RESULTS: We analyzed 1,642 of 1,703 employees without previous diagnosis of COVID-19 at onset of the study period: 53.34% of employees were referred to telework at home and did not receive intervention (Group 1, G1); 24.66% remained working on-premises in the state of São Paulo and received the intervention (Group 2, G2); 21.98% remained working on company premises in other states and did not receive intervention (Group 3, G3). Incidence rate of COVID-19 was respectively 13.35%, 0.74%, and 67.87% (p < 0.001). The odds ratio of being infected in (1) G3 versus G1 was 13.70 (95% confidence interval [CI], 10.21 to 18.39), (2) G3 versus G2 was 283.02 (95% CI, 88.98 to 900.18), and (3) G1 versus G2 was 20.66 (95% CI, 6.53 to 65.39). LIMITATIONS: The present is a retrospective analysis of a real-world experience. We could not ensure direct observed treatment, and neither could we control adherence to general prevention measures outside company premises. CONCLUSION: The incidence of COVID-19 was significantly lower amongst on-premises employees who received the GE medication in comparison to workers who did not receive the intervention (those either at other company premises or teleworking at home).

Homeopathic Treatment of Subclinical Hypothyroidism-A Series of 19 Cases.

BACKGROUND: Subclinical hypothyroidism (SCH) is a common clinical problem. Controversy surrounds the definition, clinical importance, and need for prompt diagnosis and treatment of the mild form of SCH. AIM: The aim of the study was to analyze the evolution of serum thyroid stimulating hormone (TSH) levels after a therapeutic homeopathic intervention in women older than 40 years with SCH. METHODS: This study is a retrospective series of 19 cases of SCH, with serum TSH levels between 5 and 10 mIU/L, treated exclusively with homeopathic medicines prescribed on an individualized basis. RESULTS: Nineteen patients were included according to the inclusion and exclusion criteria. Their mean age was 56 years, they were followed for a mean duration of 69 months, the mean number of serum TSH level measurements was 18, and the intervention was successful for 13 patients. CONCLUSION: The homeopathic therapeutic intervention was successful in 68% of the patients, with serum TSH levels back within the normal range (0.5-5.0 mIU/L).

Assessment of the cytoprotective effect of the homeopathic compound Canova® on African green monkey kidney (VERO) cell line exposed to the drug dipyrone sodium.

Dipyrone or metamizole is one of the most frequently used analgesic worldwide. Despite its widespread use, this drug may exert genotoxic and cytotoxic effects on lymphocytes. Therefore, studies with therapeutic agents that may provide protection against these effects are important. The homeopathic compound Canova® (CA) appears to be a beneficial candidate for preventing DNA damage and cellular lethality, since this compound acts as an immunomodulator associated with cytoprotective actions. Hence, the aim of the present investigation was to determine the potential cytoprotective effects of CA using cell line VERO as a model. VERO cells were incubated with sodium dipyrone and subsequently subject to the comet, apoptosis and immunocytochemistry assays. Data demonstrated that sodium dipyrone induced an increase in DNA damage index (DI) employing the comet assay. However, when VERO cells were co-treated with CA at the three concentrations studied, a significant reduction in DI was observed, indicating an antigenotoxic effect attributed to CA. Further dipyrone induced an elevation in %apoptosis at 24 and 48 hr. However, when dipyrone was co-incubated with CA, a significant reduction in %apoptosis was noted at the three concentrations of CA employed. Results from immunocytochemical analysis showed a rise in the expression of caspase 8 and cytochrome C when cells were exposed to dipyrone. In contrast, co-treatment of dipyrone and CA significantly reduced the effect of dipyrone. Therefore, evidence indicated that CA acted as an anticytotoxic and antigenotoxic agent counteracting damage induced by dipyrone.

Daily intake of a homeopathic agent by dogs modulates white cell defenses and reduces bacterial counts in feces.

Motivated by conventional medicines' ineffectiveness and the appearance of bacterial resistance, homeopathic medicines are being increasingly demanded by the veterinary market. Dog feces contain high bacterial and pathogenic loads, which can cause diseases in animals and facilitate zoonotic transmission. Adequate animal immunity contributes to the elimination of potential pathogens. This work's objective was to evaluate the effects of using a homeopathic medication on blood cell counts, serum protein levels, and fecal bacterial counts in dogs. Two groups were used, each including five 19-month-old Beagle dogs. The homeopathic product Orgainfecto® was sprayed on the two daily meals in the treated group (T), at 0.5 mL/animal/day for 60 days; the group that did not receive the homeopathic was considered the control (C), who were fed only the vehicle used in the production of the homeopathic as a placebo. On days 1, 30, and 60, individual stool samples were collected for bacterial counts in the stool, blood samples for blood counts, and serum for biochemical tests. Total bacterial counts in feces were lower in group T on days 30 and 60 of the experiment, while total coliforms and E coli. were lower in this group on day 60. Total leukocyte counts were lower on day 60 in group T, unlike the neutrophil count, higher in group T on day 30, and eosinophils on day 60. However, the lymphocyte count was lower in group T on days 30 and 60. There was an increase in globulin and total protein in group T on day 60. We conclude that the tested homeopathic causes neutrophils and eosinophils' stimulation and increases globulins levels even with reduced lymphocytes. The daily consumption of homeopathic by dogs decreases the intestinal bacterial load, resulting in less environmental contamination and animal and human colibacillosis risks.

Effect of Nosodes on Lettuce, Parasitized or Not by Meloidogyne enterolobii.

BACKGROUND: Nosodes are homeopathic preparations (HPs) obtained from tissues or substances associated with the targeted disease or from culture of the pathogenic agent. Nosodes are thought to modulate host resistance, easing symptoms or promoting cure. A few studies have been published about control of plant-parasitic nematodes with HPs, but none with nosodes. Conceptually, nosodes prepared from nematode infective stages might interact with the plant's pathogen-recognition system and initiate or modulate plant resistance to nematodes. OBJECTIVE: Our goal was to investigate whether nosodes prepared from second-stage juveniles (J2) of Meloidogyne enterolobii can affect the moderate resistance already existing in the lettuce cultivar 'Elisa'. METHODS: Nosodes at the Hahnemannian concentrations (cH) 6, 18, 30 and 42 were applied on lettuce plants through irrigation, with a constant daily dosage. The nosode treatment started at the seedling stage, before nematode inoculation with 3,000 eggs + J2 per plant. A series of absolute and relative controls, and 10 replicates per treatment, were employed. At harvest, variables related to plant growth and nematode reproduction were assessed. RESULTS: The nosode at 6, 18, and 30cH reduced (p <0.05) the nematode reproduction factor and root density. The nosode effect was cH-dependent since nematode reproduction was favored by treatment with 42cH. The nosode also affected (p <0.05) lettuce roots, which presented higher or lower fresh weight and volume depending on the cH applied and the condition-parasitized or not. CONCLUSION: Nosodes obtained from Meloidogyne J2 may affect plant parasitism by nematodes, possibly by interfering with plant resistance. The nature-positive or negative-and intensity of the nosode effect depends on the cH applied to the plants. Further studies are necessary to identify which cH values are more effective in reducing nematode reproduction without causing negative side effects on plant growth.

Antimonium Tartaricum as a Possible Homeopathic Prophylactic Remedy in the COVID-19 Epidemic.

The current COVID-19 (coronavirus disease 2019) epidemic has proved challenging due to its high impact on physical and mental health. According to Hahnemann, the founder of homeopathy, in an epidemic the most severe symptoms of the clinical condition presented by the population in question should be the basis for selecting the medication that is as similar as possible to them, and which should be administered to individuals who have been exposed to the disease but have not yet developed it. This medicine is called the genus epidemicus. This study aims to demonstrate the reasoning used to propose the homeopathic medicine Antimonium tartaricum (Ant-t) as a genus epidemicus in the COVID-19 epidemic. It was decided to develop the reasoning based on the respiratory symptoms described in the epidemiological bulletins presented by the Health Surveillance Secretariat of the Ministry of Health of Brazil, as these symptoms are the most serious of the disease. After repertorization, it was confirmed in the Materia Medica that Ant-t has a high degree of similarity with these respiratory symptoms, including the most serious situations, of COVID-19. Homeopathic Ant-t is thus a possible prophylactic genus epidemicus in the COVID-19 epidemic; further studies are needed to test this conclusion.

Impact of Homeopathic Treatment on the Quality of Life of Women with Chronic Diseases: A Randomized Controlled Pragmatic Trial.

BACKGROUND: Despite the increasing demand for complementary and integrative medicine, only a few studies have evaluated the effect of these types of treatments on the quality of life (QoL) of patients with chronic diseases. The objective of this study was to evaluate the QoL of women treated with homeopathy within the Public Health System of Belo Horizonte, Brazil. METHODS: This is a prospective randomized controlled pragmatic trial. The patients were divided into two independent groups, one group underwent homeopathic treatment in the first 6-month period and the other did not receive any homeopathic treatment. In both randomized groups, patients maintained their conventional medical treatment when necessary. The World Health Organization Quality of Life abbreviated questionnaire (WHOQOL-BREF) was used for QoL analysis prior to treatment and 6 months later. RESULTS: Randomization afforded similar baseline results in three domains of QoL analysis for both groups. After 6 months' treatment, there was a statistically significant difference between groups in the physical domain of WHOQOL-BREF: the average score improved to 63.6 ± (SD) 15.8 in the homeopathy group, compared with 53.1 ± (SD) 16.7 in the control group. CONCLUSIONS: Homeopathic treatment showed a positive impact at 6 months on the QoL of women with chronic diseases. Further studies should be performed to determine the long-term effects of homeopathic treatment on QoL and its determinant factors.

Homeopathy for Covid-19 in Primary Care: A structured summary of a study protocol for a randomized controlled trial.

OBJECTIVES: To investigate the effectiveness and safety of homeopathic medicine Natrum muriaticum (LM2) for mild cases of COVID-19 in Primary Health Care. TRIAL DESIGN: A randomized, two-armed (1:1), parallel, placebo-controlled, double-blind, clinical trial is being performed to test the following hypotheses: H0: homeopathic medicines = placebo (null hypothesis) vs. H1: homeopathic medicines ≠ placebo (alternative hypothesis) for mild cases of COVID-19 in Primary Care. PARTICIPANTS: Setting: Primary Care of São Carlos - São Paulo - Brazil. One hundred participants aged 18 years or older, with Influenza-like symptoms and a positive RT-PCR for SARS-CoV-2. Willingness to give informed consent and to comply with the study procedures is also required. Exclusion criterium: severe acute respiratory syndrome. INTERVENTION AND COMPARATOR: Homeopathy: 1 globule of Natrum muriaticum LM2 diluted in 20 mL of alcohol 30% and dispensed in a 30 ml bottle. Placebo: 20 mL of alcohol 30% dispensed in a 30 ml bottle. Posology: one drop taken orally every 4 hours (6 doses/day) while there is fever, cough, tiredness, or pain (headache, sore throat, muscle aches, chest pain, etc.) followed by one drop every 6 hours (4 doses/day) until the fourteenth day of use. The bottle of study medication should be submitted to 10 vigorous shakes (succussions) before each dose. Posology may be changed by telemedicine, with no break in blinding. Study medication should be maintained during home isolation. According to the Primary Care protocol, the home isolation period lasts until the 10th day after the appearance of the first symptom, or up to 72 hours without symptoms. MAIN OUTCOMES: The primary endpoint will be time to recovery, defined as the number of days elapsed before all COVID-19 Influenza-like symptoms are recorded as mild or absent during home isolation period. Secondary measures are recovery time for each COVID-19 symptom; score of the scale created for the study (COVID-Simile Scale); medicines used during follow-up; number of days of follow-up; number of visits to emergency services; number of hospitalizations; other symptoms and Adverse Events during home isolation period. RANDOMISATION: The study Statistician generated a block randomization list, using a 1:1 ratio of the two groups (denoted as A and B) and a web-based tool ( http://www.random.org/lists ). BLINDING (MASKING): The clinical investigators, the statistician, the Primary Care teams, the study collaborators, and the participants will remain blinded from the identity of the two treatment groups until the end of the study.

Prevalence and Likelihood Ratio of Six Objective Signs among Good Responders to Natrum muriaticum: Multi-centre Observational Assessment.

BACKGROUND: The reliability of homeopathic prescriptions may increase through resource to objective signs and guiding symptoms with significant positive likelihood ratio (LR). We estimated LR for six objective signs attributed to the homeopathic medicine Natrum muriaticum (Nat-m). METHODS: In this multi-centre observational assessment, we investigated the prevalence of six signs in the general patient population and among good responders to Nat-m in daily homeopathic practice. Next, we calculated LR for these six signs. RESULTS: Data from 36 good responders to Nat-m and 836 general population patients were compared. We found statistically significant positive LR (95% confidence interval) for signs such as lip cracks (1.94; 1.15 to 3.24), recurrent herpes (2.29; 1.20 to 4.37), hairline eruptions (2.07; 1.03 to 4.18), and dry hands (2.13; 1.23 to 3.69). CONCLUSIONS: Objective signs with significant positive LR might increase the reliability of homeopathic prescriptions. Further studies are warranted to confirm the validity of this approach.

Effect of Homeopathic Preparations on Lettuce, Parasitized or Not by Meloidogyne enterolobii.

BACKGROUND: There are relatively few scientific works on the use of homeopathy to manage plant pathogens, particularly nematodes. A handful of studies focused on Meloidogyne spp. parasitizing vegetables have brought contradictory results on nematode control and enhancement of plant tolerance to parasitism. OBJECTIVE: Our goal was to assess the effect of Cina-a well-known anti-nematode ingredient-on Meloidogyne enterolobii parasitizing lettuce. METHODS: Cina was applied daily on nematode-inoculated plants, from the seedling stage until harvest. We tested an evenly spaced range of Hahnemannian concentrations (c), which were applied though irrigation with a constant dose of the ingredient. Several absolute and relative controls were employed to allow the assessment of the effect of Cina on nematode reproduction and lettuce growth. RESULTS: Cina affected growth of non-parasitized plants, both positively and negatively; this effect was modulated by the c applied and the thermal stress suffered by the plants in one of the assays. The effect of Cina on the growth of nematode-parasitized plants was neutral or negative. Cina reduced nematode reproduction by 25-36%. CONCLUSION: Based on the moderate negative effect of Cina on M. enterolobii reproduction, it seems this ingredient may be useful as a complementary strategy for Meloidogyne control. But Cina did not enhance the tolerance of lettuce to Meloidogyne spp.

Silicea terra and Zincum metallicum Modulate the Activity of Macrophages Challenged with BCG In Vitro.

BACKGROUND: The homeopathic medicines Silicea terra (Sil) and Zincum metallicum (Zinc) modulate macrophage activity and were assessed in an experimental study in-vitro for their effects on macrophage-BCG (Bacillus Calmette-Guérin) interaction. METHODS: RAW 264.7 macrophages were infected with BCG, treated with different potencies of Sil and Zinc (6cH, 30cH and 200cH) or vehicle, and assessed 24 and 48 h later for bacilli internalization, hydrogen peroxide (H2O2) and cytokine production, and lysosomal activity. RESULTS: Treatment with vehicle was associated with non-specific inhibition of H2O2 production to the levels exhibited by uninfected macrophages. Sil 200cH induced significant reduction of H2O2 production (p < 0.001) compared with the vehicle and all other treatments, as well as higher lysosomal activity (p ≤ 0.001) and increased IL-10 production (p ≤ 0.05). Such effects were considered specific for this remedy and potency. The number of internalized bacilli was inversely proportional to Zinc potencies, with statistically significant interaction between dilution and treatment (p = 0.003). Such linear-like behavior was not observed for Sil dilutions: peak internalization occurred with the 30cH dilution, accompanied by cellular degeneration, and IL-6 and IL-10 increased (p ≤ 0.05) only in the cells treated with Sil 6cH. CONCLUSION: Sil and Zinc presented different patterns of potency-dependent effect on macrophage activity. Bacterial digestion and a balanced IL-6/IL-10 production were related to Sil 6cH, though reduced oxidative stress with increased lysosomal activity was related to Sil 200cH. Degenerative effects were exclusively related to Sil 30cH, and potency-dependent phagocytosis was related only to Zinc.

Homeopathy in Experimental Cancer Models: A Systematic Review.

BACKGROUND: Complementary and alternative medicine, including homeopathy, is widely used to improve well-being among cancer patients and reduce adverse effects of conventional treatment. In contrast, there are few studies on the use of homeopathic medicines to treat the disease itself. Yet, evidence of possible effectiveness of homeopathic high dilutions in experimental cancer models has been published during the past 20 years. AIM: The aim of the study was to perform a systematic review of fundamental research studies on homeopathic high dilutions in cancer. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, we conducted a literature search in the database PubMed for original publications, from 2000 to 2018 and in English, on in vitro and in vivo experimental cancer models testing homeopathic high dilutions. RESULTS: Twenty-three articles met the inclusion criteria-14 in vitro, eight in vivo, and one in vitro plus in vivo experimental models. Most studies were from India. Research prominently focused on cytotoxic effects involving apoptotic mechanisms. Intrinsic aspects of homeopathy should be considered in experimental designs to emphasize the specificity of such effects. CONCLUSION: Fundamental research of homeopathy in cancer is still at an early stage and has mainly been performed by a few groups of investigators. The results point to an interference of well-selected homeopathic medicines with cell cycle and apoptotic mechanisms in cancer cells. However, these findings still need independent reproduction.
