Berberine, dosing and safety - wellness.com - 0 views

  •  
    Side Effects and Warnings Berberine has been reported to cause nausea, vomiting, hypertension (high blood pressure), respiratory failure and paresthesias (abnormal sensations such as numbness or tingling); however, clinical evidence of such adverse effects is not prominent in the literature. Rare adverse effects including headache, skin irritation, facial flushing, headache, bradycardia (slowed heart rate) have also been reported with the use of berberine. Use cautiously when taking berberine for longer than eight weeks due to theoretical changes in bacterial gut flora. Use cautiously in individuals with diabetes, as both human and animal studies indicate that berberine may decrease blood sugar levels. Also use cautiously in individuals with hypotension (low blood pressure), as berberine may have antihypertensive effects. Patients with cardiovascular disease should also use caution as berberine has been associated with the development of ventricular arrhythmias in subjects with congestive heart failure. Although not well studied in humans, berberine may also theoretically cause delays in small intestinal transit time or increase the risk of bleeding. Berberine may cause abortion, eye or kidney irritation, nephritis (inflamed kidneys), dyspnea (difficulty breathing), flu-like symptoms, giddiness, lethargy, or liver toxicity. Patients with leukopenia (abnormally low white blood cell count) should use cautiously due to the potential for development of leukopenia symptoms. When injected under the skin, berberine may cause hyperpigmentation in the arm. Use berberine cautiously in individuals with high exposure to sunlight or artificial light due to potential for adverse phototoxic reactions. Avoid in newborns due to potential for increase in free bilirubin, jaundice, and development of kernicterus (brain damage caused by severe newborn jaundice). Use berberine cautiously in children due to a lack of safety information. Pregnancy and Breastfeeding Berberine is not recomme

Berberine : Information on Uses, Dosage & Side Effects on Healthline.com - 0 views

  •  
    "Berberine is a bitter-tasting, yellow, plant alkaloid with a long history of medicinal use in Chinese and Ayurvedic medicine. Berberine is present in the roots, rhizomes and stem bark of various plants including Hydrastis canadensis (goldenseal), Coptis chinensis (coptis or goldenthread), Berberis aquifolium (Oregon grape), Berberis vulgaris (barberry), and Berberis aristata (tree turmeric). Berberine has also been used historically as a dye, due to its yellow color. Clinical trials have been conducted using berberine. There is some evidence to support its use in the treatment of trachomas (eye infections), bacterial diarrhea, and leishmaniasis (parasitic disease). Berberine has also shown antimicrobial activity against bacteria, viruses, fungi, protozoans, helminths (worms), and chlamydia (STD). Future clinical research is warranted in these areas, as well as cardiovascular disease, skin disorders, and liver disorders.

Sloan-Kettering - Coriolus Versicolor - 1 views

  •  
    Coriolus versicolor is a mushroom of the Basidiomycetes class. It was used initially in Traditional Chinese medicine as a tonic, but recent studies suggest that it has immunostimulant and anti-tumor properties. Polysaccharide-K (PSK), a proprietary product derived from Coriolus, was developed for cancer treatment in Japan. When used as an adjuvant, PSK appears to improve survival rates in patients with gastric (1) (2) and colorectal (3) (4) (5) cancers. Other Coriolus extracts, such as polysaccharide-peptide (PSP) and VPS, are available as dietary supplements. When used in conjunction with chemotherapy, PSP may benefit patients with advanced non-small cell lung cancer (7). Other clinical studies using Coriolus extract alone or in combination with other botanicals also suggest positive immunomodulatory effects (8) (9). However, studies on breast cancer (10), hepatocellular carcinoma (11), and leukemia (12) produced mixed results. A hot water extract of Coriolus, VPS, was found to enhance development of large intestinal tumors in mice (21). Coriolus extracts are generally well tolerated but minor adverse effects have been reported. Many over-the-counter Coriolus products are not standardized, making it difficult to compare potency between brands. It is also unclear if PSK, PSP and other Coriolus extracts have comparable effects.

DCA and vanadium combination - The DCA Site - Updating You on DCA and Cancer - Dichloro... - 1 views

  •  
    Simultaneously Blocking Glycolysis and Fat Metabolism Can the use of DCA and a fatty acid metabolism blocker together force more cancer cells into using aerobic metabolism? Tim McGough used green tea extract, which contains EGCG, in his fantastic response. DCA works by reactivating mitochondria and shifts metabolism from glycolysis to glucose oxidation. Hopefully the cancer cell will then undergo apoptosis. However, cancer cells have an alternate energy source: fat metabolism. This page explores to possibility of blocking fat metabolism to help force the cell into apoptosis. Oral squamous cell carcinoma is a cancer that does not respond well to DCA. This study, Head and Neck Cancer Cell Lines Are Resistant to Mitochondrial-Depolarization-Induced Apoptosis states: "Results: ΔΨm in head and neck cell lines started to show slight loss of ΔΨm, while HL-60 showed significant loss of ΔΨm after 30 min of treatment. All cell lines demonstrated complete mitochondrial depolarization within 24 h, however, only the control cell line HL-60 underwent apoptosis. In addition, HNSCC cell lines did not demonstrate cytoplasmic cytochrome c release despite significant mitochondrial membrane depolarization, while HL-60 cell initiated apoptosis and cytochcrome c release after 24 h of treatment. Conclusions: Head and neck cancer cell lines exhibit defects in mitochondrial-membrane-depolarization-induced apoptosis as well as impaired release of cytochrome c despite significant mitochondrial membrane depolarization. Proximal defects in the mitochondrial apoptosis pathway are a feature of HNSCC.(head and neck squamous cell carcinoma)" Note that although the cell lines were depolarized, apoptosis did not occur. So I checked to see if fatty acid metabolism is used by squamous cell carcinoma.

PSK: A Non-Toxic Polysaccharide Drug - 0 views

  •  
    If you're from Japan, you're probably wondering why I've listed PSK under alternative therapies. In Japan, PSK is an approved anti-cancer drug with 20 years of research behind it. PSK sales in Japan account for hundreds of millions dollars worth of sales each year. But in the US, PSK is little known, is not used by mainstream doctors, and until recently nothing like it was readily available. Now a nutritional supplement designed to be identical to PSK is available in the US, but very few mainstream doctors, and actually not many alternative practitioners are aware of it. So in the US, PSK has the status of a little known nutritional supplement or alternative therapy. Which is too bad in light of its proven benefits, easy administration, and lack of toxicity. Before I start sounding too much more like an advertisement, let me confess. I really am excited about it, but I have no financial interest in it; I'm not selling it.

Mechanisms of Berberine (Natural Yellow 18)-Induced Mitochondrial Dysfunction: Interact... - 0 views

    Mechanisms of berberine (natural yellow 18)-induced mitochondrial dysfunction: interaction with the adenine nucleotide translocator. Pereira CV, Machado NG, Oliveira PJ. Toxicol Sci. 2008 Oct;105(2):408-17. Epub 2008 Jul 3. PMID: 18599498 doi: 10.1124/jpet.107.128017 The data from the present work appear to show that berberine also presents some degree of toxicity to "nontumor" systems, which should be carefully understood. ANT inhibition in nontumor cells by berberine would be responsible for a decrease in energy production and could also result in MPT induction. To the best of our knowledge, no full toxicity assessment exists for berberine in humans, although its use in several commercially available supplements suggests that the compound may present a relatively wide safety interval. In fact, a study with patients with congestive heart failure treated with 1.2 g/day of oral berberine revealed low toxicity and resulted into an average plasma concentration of 0.11 mg/l which would translate into 0.3µM (Zeng and Zeng, 1999Go). Repeated cumulative treatments, alternative forms of formulation (e.g., topical application vs. injection) or more importantly, active mitochondrial accumulation due to its positive charge would be expected to increase its concentration in cells into the range of concentrations used in this study. Empirical data from nontraditional medicines plus the use of extensive clinical assays would allow the use of berberine as a promising antimelanoma agent while maintaining its safety for humans. In radial/vertical forms of melanoma, a possible topical application of berberine would also be possible, thus minimizing side effects on other organs. In conclusion, the present work identifies the ANT as an important target for berberine, with clear relevance for its proposed antitumor effects.

    Berberine and Coptidis rhizoma as novel antineoplastic agents: a review of traditional use and biomedical investigations. Tang J, Feng Y, Tsao S, Wang N, Curtain R, Wang Y. J Ethnopharmacol. 2009 Oct 29;126(1):5-17. Epub 2009 Aug 15. PMID: 19686830 doi:10.1016/j.jep.2009.08.009 Conclusions The modern evidences of treating cancer with Huanglian and berberine have a strong linkage with traditional concept and rules of using Huanglian in CM practice. As anticancer candidates with low toxicity, berberine and its altered structure, as well as Huanglian and its formulae, will attract scientists to pursue the potential anticancer effects and the mechanisms by using technologies of genomics, proteomics and other advanced approaches. On the other hand, relatively few in vivo studies have been conducted on anticancer effects of Huanglian and berberine. The clinical application of berberine or Huanglian as novel cancer therapeutic agents requires in vivo validations and further investigations of their anticancer mechanisms.

What's Feeding Cancer Cells? - 0 views

  •  
    ScienceDaily (Feb. 22, 2009) - Cancer cells need a lot of nutrients to multiply and survive. While much is understood about how cancer cells use blood sugar to make energy, not much is known about how they get other nutrients. Now, researchers at the Johns Hopkins University School of Medicine have discovered how the Myc cancer-promoting gene uses microRNAs to control the use of glutamine, a major energy source. The results, which shed light on a new angle of cancer that might help scientists figure out a way to stop the disease, appear Feb. 15 online at Nature

Sloan-Kettering - Astragalus - 0 views

  •  
    Astragalus root is used in traditional medicine for its immunestimulating properties. Chinese studies suggest that astragalus, when used with angelica, has renal protective effects (6). In addition, astragalus decreases the proteinuria associated with idiopathic membranous nephropathy (7) as well as possesses natriuretic action (8). Astragalus may also suppress airway hyperreactivity associated with allergic asthma in vivo (9). An herbal formula using astragalus as a major ingredient has been shown to reduce fatigue in athletes (10). Furthermore, astragalus increases M-cholinergic receptor density in senile rats (11), which suggests that it may have a role in combating senility.

    Mitochondrially targeted effects of berberine [Natural Yellow 18, 5,6-dihydro-9,10-dimethoxybenzo(g)-1,3-benzodioxolo(5,6-a) quinolizinium] on K1735-M2 mouse melanoma cells: comparison with direct effects on isolated mitochondrial fractions. Pereira GC, Branco AF, Matos JA, Pereira SL, Parke D, Perkins EL, Serafim TL, Sardão VA, Santos MS, Moreno AJ, Holy J, Oliveira PJ. J Pharmacol Exp Ther. 2007 Nov;323(2):636-49. Epub 2007 Aug 17. PMID: 17704354 doi: 10.1124/jpet.107.128017 The present work shows that berberine is accumulated by mitochondria of a mouse melanoma cell line, leading to mitochondrial fragmentation and dysfunction, accompanied by decreased cellular energy charge. When the effect was compared with the results obtained on isolated mitochondrial fractions, it is observed that regardless of the system used, berberine is toxic for mitochondria. One major limitation of the present study (as in many others) is the lack of knowledge of the real concentration of berberine that reaches mitochondria in intact cells. Although we do not possess data regarding this aspect, it is wise to speculate that mitochondrial berberine concentrations will be much higher than in the bulk cytosol due to electrophoretic accumulation. We believe that the range of berberine concentrations accumulated by mitochondria in intact cells is within the range of concentrations used on isolated mitochondrial fractions in the present study. The present work not only provides insights on the mechanism by which berberine interferes with tumor cell proliferation, demonstrating previously unknown effects on mitochondrial physiology, but also raises a note of caution on the use of berberine as a nontoxic "natural" over-the-counter medication.

Cancer survivor credits healthful diet - denverpost.com - 0 views

    "Cancer lies dormant in all of us," he wrote in his new book, "Anticancer: A New Way of Life" (Viking, $25.95). "But our bodies are also equipped with a number of mechanisms that detect and keep such (defective) cells in check." Cancer rears its ugly head when things get out of balance, Servan-Schreiber said in an interview. And that can happen if the bad guys that promote the growth of cancer cells (tobacco, excessive alcohol, excessive sugar, hydrogenated fats, environmental pollutants) outnumber the good guys that support our natural defenses (cancer-fighting phytochemicals found in fruits, vegetables, herbs and teas; physical activity; and stress management techniques). But conventional treatment, while indispensable, focuses on a single target: destroying cancer cells. Doctors rarely address the other side: teaching patients how to fortify themselves using nutrition, exercise and stress-management techniques to create an inhospitable environment for cancer.

Technology Review: Implant Makes Cells Kill Cancer - 0 views

  •  
    A new approach to cancer treatment called immunotherapy could spare patients at least some of the grueling battery of chemotherapy treatments by retraining the body's own defenders--the cells of the immune system--to recognize and destroy tumors. Now researchers at Harvard University have developed a simple way to do this inside the body: a polymer implant attracts and trains immune-system cells to go after cancer. The experimental approach has shown great success in animal studies, increasing the survival rate of mice with a deadly melanoma from 0 to 90 percent. The implant could also be used to treat diseases of the immune system such as arthritis and diabetes, and, potentially, to train other kinds of cells, including stem cells used to repair damage to the body.

Lingzhi mushroom - Wikipedia, the free encyclopedia - 0 views

  •  
    "Língzhī (traditional Chinese: 靈芝; simplified Chinese: 灵芝; Japanese: reishi; Korean: yeongji, hangul: 영지) is the name for one form of the mushroom Ganoderma lucidum, and its close relative Ganoderma tsugae. Ganoderma lucidum enjoys special veneration in Asia, where it has been used as a medicinal mushroom in traditional Chinese medicine for more than 4,000 years, making it one of the oldest mushrooms known to have been used in medicine. Lingzhi may possess anti-tumor, immunomodulatory and immunotherapeutic activities, supported by studies on polysaccharides, terpenes, and other bioactive compounds isolated from fruiting bodies and mycelia of this fungus (reviewed by R. R. Paterson[4] and Lindequist et al.[7]). It has also been found to inhibit platelet aggregation, and to lower blood pressure (via inhibition of angiotensin-converting enzyme[8]), cholesterol and blood sugar.[9] Laboratory studies have shown anti-neoplastic effects of fungal extracts or isolated compounds against some types of cancer. In an animal model, Ganoderma has been reported to prevent cancer metastasis,[10] with potency comparable to Lentinan from Shiitake mushrooms.[11] The mechanisms by which G. lucidum may affect cancer are unknown and they may target different stages of cancer development: inhibition of angiogenesis (formation of new, tumor-induced blood vessels, created to supply nutrients to the tumor) mediated by cytokines, cytoxicity, inhibiting migration of the cancer cells and metastasis, and inducing and enhancing apoptosis of tumor cells

Sloan-Kettering - Garlic - 0 views

  •  
    Derived from the bulb or clove of the plant. Garlic is used as a spice and to treat hyperlipidemia, hypertension, atherosclerosis, cancer, and infections. Processing can have a substantial effect on the chemical content in garlic; the volatile oil components are sensitive to heat and certain enzymes are acid-labile. Several oral garlic formulations are available, and clinical studies have addressed a variety of the proposed claims. Placebo-controlled trials on the cholesterol lowering effect of garlic yielded mixed results (16) (17) (18) (21) (22) (26). Studies evaluating the antithrombotic effects repeatedly have shown modest reduction in platelet aggregation, but varying levels of fibrinolytic activity. Research shows mixed effects with regard to reductions in blood glucose, blood pressure, or risk of cardiovascular disease (23). Frequently reported adverse events include bad breath, headache, fatigue, GI upset, diarrhea, sweating, and possible hypoglycemia (9). Because garlic is known to decrease platelet aggregation and potentially elevate the INR, it should not be used with anticoagulants or in patients with platelet dysfunction (15). Garlic appears to induce cytochrome p450 3A4 and may enhance metabolism of many medications (e.g. cyclosporin and saquinavir) (12). An analysis of several case-control studies in Europe suggests an inverse association between garlic consumption and risk of common cancers (25).

Artemisinin - Wikipedia, the free encyclopedia - 0 views

  •  
    Artemisinin (pronounced /ɑːtə'misinən/) is a drug used to treat multi-drug resistant strains of falciparum malaria. The compound (a sesquiterpene lactone) is isolated from the plant Artemisia annua. Not all plants of this species contain artemisinin. Apparently it is only produced when the plant is subjected to certain conditions, most likely biotic or abiotic stress. It can be synthesized from artemisinic acid.[1] The drug is derived from a herb used in Chinese traditional medicine, though it is usually chemically modified and combined with other medications. Artemisinin is under early research and testing for treatment of cancer, primarily by researchers at the University of Washington.[7][8] Artemisinin has a peroxide lactone group in its structure. It is thought that when the peroxide comes into contact with high iron concentrations (common in cancerous cells), the molecule becomes unstable and releases reactive oxygen species. It has been shown to reduce angiogenesis and the expression of vascular endothelial growth factor in some tissue cultures.
