Homeopathic drug standardization through biological evaluations: An untrodden avenue

Background: There is a dearth of chemico-analytical or instrumental methods for standardization and quality control of higher dilutions of homeopathic drugs. Aim: This review highlights the challenges in standardization of anti-inflammatory homeopathic drugs and suggests a battery of biological assays for their standardization. Methods: We retrieved a total 57 scientific reports from the experimental studies and scientific reviews published between January 1999 and June 2014 related to anti-inflammatory homeopathic drugs and their high dilutions. These comprised of 18 reports on preclinical evaluation, 15 on source materials, 9 on isolated constituents and 15 studies on in-vitro experiments. Few recent citations which supported the initial studies were added later during the compilation of the manuscript. Conclusion: Standardization and quality control of homeopathic mother tinctures and high dilutions warrants an urgent attention. As biological activities are observed to be attributed to the high dilutions which are practically devoid of active ingredients, their standardization may be done through the suggested battery of biological investigations. It is suggested that the current methods of standardization of homeopathic drugs need to be upgraded to include sensitive, reproducible and relevant biological assays so that the end users are assured of the quality, efficacy, and safety of homeopathic dilutions.

Arnica Montana. Una revisión bioquímica y homeopática / Arnica Montana. A biochemical and homeopathic review

El Arnica montana es uno de los medicamentos que se emplean con mayor frecuencia en la práctica homeopática. Comúnmente, es la primera elección en la atención de traumatismos, contusiones y golpes, especialmente de partes blandas. También se emplea en torceduras, fracturas, esfuerzos exagerados, enfermedades reumáticas, traumas emocionales y para mejorar la recuperación de los pacientes que se someten a intervenciones quirúrgicas. Debido al interés que genera, el Arnica montana ha sido objeto de numerosos estudios en diferentes áreas para comprobar su alcance y determinar sus mecanismos de acción. A continuación se presenta una revisión de algunos artículos publicados sobre este medicamento; unos versan sobre sus principios activos y otros analizan diversos experimentos que se han efectuado.

Arnica montana is one of the most often used drugs in homeopathic practice. Commonly, it is the first choice in the trauma care, bruises and bumps, especially soft tissue. Also used in sprains, fractures, exaggerated efforts, rheumatic diseases and emotional trauma to improve recovery of patients who undergo surgery. Due to the interest generated, Arnica montana has been the subject of numerous studies in different areas to check their range and determine their mechanisms of action. Below is a review of some articles published on this medication, some deal with other active principles and discusses various experiments that have been conducted.(AU)

Study of high dilutions of copaiba oil on inflammatory process / Estudo de altas diluições homeopáticas do óleo de copaíba

The discovery of new drugs has led to a need to develop techniques to control the occurrence of toxic and collateral effects. This has enabled the advancement of homeopathic therapeutics as it presents major advantages against these effects. This study was designed to explore the effects of high dilutions of Copaifera (copaiba oil) on inflammation. This study considered the way the high dilutions were obtained (triturated form or mother-tincture-MT). The preparations were administered orally. The effects of the dilutions were tested using the rat paw edema induced by carrageenan; granuloumatous tissue induction and the edema induced by Croton oil. The high dilutions of copaiba oil obtained from both trituration and MT produced a statistically significant inhibitory effect of the carrageenan edematogenic process compared to control. The maximum effect was observed with dilution 30cH, with inhibition of edema by 73%, whereas indomethacin was 55%. Subcutaneous implantation of cotton pellets have induced a granulomatous tissue, evaluated 7 days after implantation. Daily treatment with dexamethasone produced 53% inhibition on the formation of granulomatous tissue. The 6cH dilution of copaiba oil inhibited in a statistically significant way the formation of granulomatous tissue compared to the control (18% and 16%, respectively). Edema in Croton-oil induced dermatitis was intense. Groups treated with dexamethasone and dilutions of copaiba oil presented similar responses, with inhibition by 57% and 48% respectively. Based on the results obtained in this study, it may be suggest that the Copaiba oil high dilutions possess an anti-inflammatory property supporting its use in the treatment of inflammatory disorders.(AU)

A descoberta de novas drogas tem gerado a necessidade de desenvolvimento de novas técnicas para controle da ocorrência de efeitos tóxicos e colaterais. Isto tem favorecido o uso da terapêutica homeopática uma vez que esta apresenta vantagens contra alguns efeitos adversos. Este trabalho foi proposto visando explorar os efeitos de Altas Diluições de Copaifera (óleo de copaíba) sobre inflamação. Foi considerada a maneira como as altas diluições foram obtidas (via trituração ou via tintura-mãe). As preparações foram administradas oralmente. Os efeitos das diluições foram avaliados usando um modelo de edema em pata de ratos, induzido por carragenina, indução de tecido granulomatoso e edema induzido pelo óleo de Croton. As altas diluições de óleo de Copaíba obtidas a partir de trituração e de tintura-mãe produziram efeitos inibitórios estatisticamente significativos para o processo endematogênico, quando comparado com o controle. O efeito máximo foi obtido com a diluição 30cH, com uma inibição de 73% do edema, enquanto a indometacina inibiu 55%. O implante subcutâneo de pellets de algodão induziram a granulomatose do tecido, avaliados 7 dias após o implante. Tratamento diário com dexametasona produziu 53% de inibição da formação de tecido granulomatoso. A diluição 6cH do óleo de copaíba inibiu de forma significativa a formação de tecido granulomatoso, comparado com o controle (18% e 16% respectivamente). Edema em dermatite induzida por óleo de Croton foi intensa. Grupos tratados com dexametasona e diluições de óleo de copaíba apresentaram respostas similares, com inibição de 57% e 48% respectivamente. Baseado nos resultados obtidos, pode-se concluir que altas diluições do óleo de copaíba apresentam efeitos anti-inflamatórios, sugerindo seu uso no tratamento de desordens inflamatórias.(AU)

Les remedes de l'inflammation: Aconit, Belladonna, Ferrum phosphoricum / Drugs of inflammation: Aconitum, Belladona, Ferrum phosphoricum

Les etats inflammatoires sont caracterises par les signes de la tetrade classique: rubour (rouger), calor (chaleur, fievre), tumor (tumefaction), dolor (douleur). C'est leur degre d'intensite ainsi que les symptomes associes qui vont permettre de differencier ces trois remedes piliers de la therapeutique homeopathique. (AU)

A chemo-pharmacological study of Hypericum perforatum L

Arthritis was produced in adult albino rats weighing 120+-10g through intramuscular injections of 0.5ml of 2 percent w/w formalin beneath the plantar aponeurosis on the first and third day. The anterioposterior diameter of the ankle was recorded and statistically analyzed. It was evident that relatively low doses, 0.25ml/100g body weight, of tincture of Hypericum perforatum produced a significant 48 percent anti-inflammatory effect, whereas higher doses, 0.5ml/100g body weight, of the drug showed 32 percent activity under identical conditions. Parallel studies with 1mg/100g body weight hydrocortisone administration gave similar anti-inflammatory effects. Local application of an alcoholic extract of the drug in very small doses also produced significant skin softness and flexiblility of muscle

Effet de belladonna et ferrum phosphoricum sur la chemiluminescence des polynucleaires neutrophiles humains / Belladona and ferrum phosphoricum effect in chemiluminiscence of polinuclear neutrophiles

Dans cette experimentation, les auteurs ont etudie l'activite de dilutions 5CH et 9CH de Belladonna et Ferrum Phosphoricum sur la liberation de radicaux oxygenes libres, impliques dans l'initiation et l'entretien des phenomenes inflammatoires. Belladonna et Ferrum Phosphoricum entrainent une inhibition significative de la liberation de radicaux libres. Cette inhibition est, sur une population de sujets sensibles, comparable a celle due a l'indometacine l0-4M et a la dexamethasone l0-5M
