In Vitro Assessment of Homeopathic Potencies of Hydrastis canadensis on Hormone-Dependent and Independent Breast Cancer.

BACKGROUND: Breast cancer is the second leading cause of cancer-related deaths in women. Conventional treatment such as chemotherapy, hormonal therapy and radiotherapy has decreased the mortality rate among cancer patients but has also revealed long-term side effects. Drug resistance and toxicity to normal cells compound the problems associated with the use of modern medicines. Hence, complementary or alternative treatment options are being explored. The current study, using different homeopathic potencies of Hydrastis canadensis, was conducted to distinguish between any effects they might have on hormone-dependent and independent breast cancer. MATERIALS AND METHODS: The cytotoxic effect of homeopathic medicine Hydrastis on hormone-dependent (MCF 7) and hormone-independent (MDA-MB-468) breast cancer cells was assessed using viability and colony-forming assays after 48 or 72 hours of treatment. Flow cytometry-based Annexin V-PI (propidium iodide), caspase 3 and cell cycle analysis was performed following treatment of cells with mother tincture or various potencies of Hydrastis (1C, 2C, 30C, 200C). RESULTS: Different potencies of Hydrastis displayed selective cytotoxic effects against MCF 7 cells, but only marginal effects against MDA-MB-468. The maximum cytotoxicity was established in the case of 1C following 72 hours of treatment. Treatment of breast cancer cells revealed an increase in the G0/G1 cell population, along with an increase in the caspase 3 levels and induction of apoptosis. CONCLUSION: Hydrastis may have a selective cytotoxic effect against hormone-dependent breast cancer MCF 7 cells, leading to cell cycle arrest in the G0/G1 phase, which could be the plausible reason for the induction of apoptosis. The results need to be validated in vivo.

Usefulness of Hydrastis for the prevention of encrustation of long-term indwelling catheters in persons with neurogenic bladder dysfunction: a case series.

INTRODUCTION: Virtually every person with a spinal cord injury (SCI) suffers from a neurogenic lower urinary tract dysfunction (NLUTD). In the long term, about 15% of persons with SCI depend on indwelling (suprapubic or transurethral) catheters for bladder management. About 50% of these patients suffer from catheter encrustation and blockage, which may become a vital threat for persons with SCI, as it can lead to septicemia or autonomic dysreflexia. Until today, no prophylaxis of catheter encrustations with an evidence-based proof of efficacy exists. CASE PRESENTATION: The homeopathic remedy Hydrastis, made from the goldenseal root, is used for the treatment of thick, mucous urine sediment. In four patients with tetraplegia (three female, one male) who managed NLUTD by suprapubic catheters, recurrent encrustations and catheter blockage occurred despite irrigation and medical treatment. Surgical urinary diversion was envisioned. Applying Hydrastis C30 once weekly as a long-term medication, in three of the four patients, catheter obstructions ceased, with a follow-up for at least 1 year. One patient is awaiting ileal conduit surgery. DISCUSSION: According to the results of our case series, the application of Hydrastis seems to be beneficial in the prevention of encrustations of indwelling catheters in patients with SCI. As the treatment was effective and well tolerated, the problem is frequent, and effective solutions are scarce, a prospective trial seems justified.

Effect of homeopathic medicines on transplanted tumors in mice.

Ultra low doses used in homeopathic medicines are reported to have healing potential for various diseases but their action remains controversial. In this study we have investigated the antitumour and antimetastatic activity of selected homeopathic medicines against transplanted tumours in mice. It was found that Ruta graveolens 200c and Hydrastis canadensis 200c significantly increased the lifespan of Ehrlich Ascites Carcinoma and Dalton's Lymphoma Ascites induced tumour-bearing animals by 49.7%, and 69.4% respectively. Moreover there was 95.6% and 95.8% reduction of solid tumour volume in Ruta 200c and Hydrastis 200c treated animals on the 31st day after tumour inoculation. Hydrastis 1M given orally significantly inhibited the growth of developed solid tumours produced by DLA cells and increased the lifespan of tumour bearing animals. Some 9 out of 15 animals with developed tumors were completely tumour free after treatment with Hydrastis 1M. Significant anti-metastatic activity was also found in B16F-10 melanoma-bearing animals treated with Thuja1M, Hydrastis 1M and Lycopodium1M. This was evident from the inhibition of lung tumour nodule formation, morphological and histopathological analysis of lung and decreased levels of gamma-GT in serum, a cellular marker of proliferation. These findings support that homeopathic preparations of Ruta and Hydrastis have significant antitumour activity. The mechanism of action of these medicines is not known at present.

Biosynthesized silver nanoparticles by ethanolic extracts of Phytolacca decandra, Gelsemium sempervirens, Hydrastis canadensis and Thuja occidentalis induce differential cytotoxicity through G2/M arrest in A375 cells.

The capability of crude ethanolic extracts of certain medicinal plants like Phytolacca decandra, Gelsemium sempervirens, Hydrastis canadensis and Thuja occidentalis used as homeopathic mother tinctures in precipitating silver nanoparticles from aqueous solution of silver nitrate has been explored. Nanoparticles thus precipitated were characterized by spectroscopic, dynamic light scattering, X-ray diffraction, atomic force and transmission electron microscopic analyses. The drug-DNA interactions of silver nanoparticles were analyzed from data of circular dichroism spectroscopy and melting temperature profiles using calf thymus DNA (CT-DNA) as target. Biological activities of silver nanoparticles of different origin were then tested to evaluate their effective anti-proliferative and anti-bacterial properties, if any, by exposing them to A375 skin melanoma cells and to Escherichia coli C, respectively. Silver nanoparticles showed differences in their level of anti-cancer and anti-bacterial potentials. The nanoparticles of different origin interacted differently with CT-DNA, showing differences in their binding capacities. Particle size differences of the nanoparticles could be attributed for causing differences in their cellular entry and biological action. The ethanolic extracts of these plants had not been tested earlier for their possible efficacies in synthesizing nanoparticles from silver nitrate solution that had beneficial biological action, opening up a possibility of having therapeutic values in the management of diseases including cancer.

Induction of apoptosis of tumor cells by some potentiated homeopathic drugs: implications on mechanism of action.

BACKGROUND: Homoeopathic medicines treat diseases, including cancer, using ultradiluted preparations. Earlier studies indicated that homoeopathic medicines are cytotoxic to tumor cells and reduced animal tumors. However, the mechanism of homoeopathic medicines at the cellular level is not known. METHODS: The following drugs were used in the study: Ruta 200C, Carcinosinum 200C, Hydrastis 200C, Thuja 200C, and Thuja 1M. These drugs were tested for their ability to induce apoptosis as seen by morphology, DNA laddering, expression of genes related to apoptosis, and TUNEL assay. Similarly, the effect of homoeopathic medicines on apoptosis was measured by microarray analysis. Activity of Ruta 200C was compared with that of the mother tincture. RESULTS: Ruta 200C produced morphological changes in the Dalton's lymphoma ascites tumor cells and induced DNA laddering. Carcinosinum 200C increased apoptotic gene p53 and Ruta 200C decreased antiapoptotic gene Bcl2. Administration of potentiated homoeopathic drugs to tumor-bearing mice induced TUNEL-positive cells in the tumor, showing increased apoptosis of tumor cells. Microarray analysis of cells treated with homoeopathic drugs indicated that many enzymes related to apoptosis were increased by homoeopathic drugs. CONCLUSION: These data indicate that apoptosis is one of the mechanisms of tumor reduction of homeopathic drugs. A comparison of potentiated drugs with their mother tincture indicated that the potentiated drugs have biological activity similar to that of their mother tincture in spite of ultradilution.

Evidence in support of gene regulatory hypothesis: Gene expression profiling manifests homeopathy effect as more than placebo

Background: Use of ultra-high diluted remedies in homeopathy and their claimed efficacy in curing diseases has been challenged time and again by non-believers despite many evidence-based positive results published in favor of their efficacy in curing/ameliorating disease symptoms. Aims: To test the ability of ultra-high diluted homeopathic remedies beyond Avogadro’s limit, if any, in manifesting gene modulating effects in controlled in vitro experimental model. Methods: Since cancer cells manifest aberrant epigenetic gene expressions, we conducted global microarray gene expression profiling of HeLa cells (an established epigenetic model of HPV18 positive cell line) treated with two different potentized homeopathic remedies, namely, Condurango 30c and Hydrastis canadensis 30C (used in the treatment of cancer), as compared to that of placebo (succussed alcohol 30c). Results: Data revealed distinctly different expression patterns of over 100 genes as a consequence of treatment with both homeopathc remedies compared to placebo. Conclusion: Results indicate that action of the potentized drugs was “more than placebo” and these ultra-highly diluted drugs acted primarily through modulation of gene expression.

Introdução: O uso de medicamentos homeopáticos ultra-diluídos e a sua presumível eficácia na cura de doenças têm sido reiteradamente contestados por céticos, apesar dos muitos resultados positivos, baseados em evidências, demonstrando a sua eficácia na cura/melhora de sintomas patológicos. Objetivos: Testar a possível capacidade de medicamentos homeopáticos diluídos além do limite de Avogadro para apresentar efeitos de modulação genética em modelo experimental in vitro. Métodos: Sendo que as células neoplásicas manifestam expressões epigenéticas aberrantes, investigamos através de micro-arranjo o perfil global de expressão genética de células HeLa (modelo epigenético já estabelecido de linhas celulares HPV18 positivas) tratadas com 2 medicamentos homeopáticos dinamizados, a saber, Condurango 30c e Hydrastis canadensis 30c (utilizados no tratamento de neoplasias) comparados com um placebo (álcool sucussionado 30c). Resultados: Os dados indicaram diferentes perfis de expressão em mais de 100 genes nas células tratadas com os medicamentos homeopáticos por comparação ao placebo. Conclusão: Os resultados indicam que o efeito dos medicamentos dinamizados foi “mais do que placebo” e que essa ação foi principalmente mediada por modulação da expressão genética.

Top-10 list of herbal and supplemental medicines used by cosmetic patients: what the plastic surgeon needs to know.

BACKGROUND: Widespread use of herbal medications/supplements among the presurgical population may have a negative effect on perioperative patient care. Thus, the authors' goal was to identify the prevalence of such use in a cosmetic surgery patient population compared with use among the general public; to assess physician awareness of proper management of these herbal medications/supplements; and to review the literature to provide rational strategies for managing perioperative patients taking these remedies. METHODS: To assess patient (n = 100) and general public (n = 100) usage rates, open-ended lists of (1) the most common herbal medications/supplements and (2) homeopathic treatments were compiled. Board-certified plastic surgeons (n = 20) were then given the same list of herbs/supplements and surveyed on their awareness of these treatments and perioperative side effects. RESULTS: The usage rate for cosmetic versus public surveys for herbal medicines/supplements was 55 percent versus 24 percent (p < 0.001), with 35 percent versus 8 percent (p < 0.001) engaging in homeopathic practices, respectively. Cosmetic patients' top four herbal/supplements of usage were chondroitin (18 percent), ephedra (18 percent), echinacea (14 percent), and glucosamine (10 percent). The top four used by the general public were echinacea (8 percent), garlic (6 percent), ginseng (4 percent), and ginger (4 percent). The physician survey demonstrated awareness of 54 percent of the listed supplements/herbal medicines, 85 percent of which were not suggested to be discontinued preoperatively, with only ephedra achieving 100 percent physician discontinuation preoperatively. CONCLUSIONS: Herbal medicines and supplements displayed greater prevalence in the cosmetic surgery population than in the population at large. Furthermore, side effects and potential complications warrant addressing these remedies as pharmaceuticals rather than as safe and "natural." Thus, a descriptive "top-10" list with perioperative recommendations was compiled for the plastic surgeon.
