Developmental toxicity evaluation of berberine in rats and mice. Jahnke GD, Price CJ, Marr MC, Myers CB, George JD. Birth Defects Res B Dev Reprod Toxicol. 2006 Jun;77(3):195-206. PMID: 16634078 DOI: 10.1002/bdrb.20075 BACKGROUND: Berberine, a plant alkaloid, is found in some herbal teas and health-related products. It is a component of goldenseal, an herbal supplement. Berberine chloride dihydrate (BCD) was evaluated for developmental toxicity in rats and mice. METHODS: Berberine chloride dihydrate was administered in the feed to timed-mated Sprague-Dawley (CD) rats (0, 3625, 7250, or 14,500 ppm; on gestational days [GD] 6-20), and Swiss Albino (CD-1) mice (0, 3500, 5250, or 7000 ppm; on GD 6-17). Ingested doses were 0, 282, 531, and 1313 mg/kg/day (rats) and 0, 569, 841, and 1155 mg/kg/day (mice). RESULTS:There were no maternal deaths. The rat maternal lowest observed adverse effect level (LOAEL), based on reduced maternal weight gain, was 7250 ppm. The rat developmental toxicity LOAEL, based on reduced fetal body weight per litter, was 14,500 ppm. In the mouse study, equivocal maternal and developmental toxicity LOAELs were 5250 ppm. Due to scattering of feed in the high dose groups, a gavage study at 1000 mg/kg/day was conducted in both species. CONCLUSIONS: In rats, maternal, but not fetal adverse effects were noted. The maternal toxicity LOAEL remained at 7250 ppm (531 mg/kg/day) based on the feed study and the developmental toxicity NOAEL was raised to 1000 mg/kg/day BCD based on the gavage study. In the mouse, 33% of the treated females died. Surviving animals had increased relative water intake, and average fetal body weight per litter decreased 5-6% with no change in live litter size. The maternal toxicity LOAEL remained at 5250 ppm (841 mg/kg/day) BCD, based on increased water consumption. The developmental toxicity LOAEL was raised to 1000 mg/kg/day BCD based on decreased fetal body weight.

"Berberine is a plant alkaloid isolated from the roots and bark of several herbs. Some of these herbs include: Barberry (Berberis vulgaris), Berberis integerrima. Berbamine and berberine are found in the plant barberry. Coptis chinensis or Berberis aristata Goldenseal (Hydrastis canadensis) Oregon Grape (Berberis aquifolium) Phellodendron Amurense Yerba mansa (Anemopsis californica). The berberine alkaloid can be found in the roots, rhizomes, stem, and bark of the plants. Berberine-containing plants are used medicinally in many traditional medical systems, including Ayurvedic herbal and Chinese herbal medicine. Coptis chinensis rhizome -- Golden Thread -- Huang Lian -- Intense yellow color most likely due to high content of berberine, which is very bitter in taste"

"The clinical potential for a liver-protective supplement in cancer care is significant, as I've observed in many years of integrative medical practice," writes Dr. Keith Block, ICT editor. "Several chemotherapy drugs, as well as many of the other drugs cancer patients take, have extremely problematic liver toxicities. With this exclusive edition, the scientific community will have a resource to guide and inspire further research on this very interesting herbal medicine."

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.

Berberine, a natural product, induces G1-phase cell cycle arrest and caspase-3-dependent apoptosis in human prostate carcinoma cells. Mantena SK, Sharma SD, Katiyar SK. Mol Cancer Ther. 2006 Feb;5(2):296-308. PMID: 16505103 doi: 10.1158/1535-7163.MCT-05-0448 The effectiveness of berberine in checking the growth of androgen-insensitive, as well as androgen-sensitive, prostate cancer cells without affecting the growth of normal prostate epithelial cells indicates that it may be a promising candidate for prostate cancer therapy. The evaluation of ancient herbal medicines may indicate novel strategies for the treatment of prostate cancer, which remains the leading cause of cancer-related deaths in American men (1). In our present investigation, we show that a naturally occurring isoquinoline alkaloid, berberine, significantly inhibits the proliferation and reduces the viability of DU145 and PC-3 as well as LNCaP cells (Fig. 1), which suggests that berberine may be an effective chemotherapeutic agent against both androgen-sensitive and androgen-insensitive prostate cancer cells. Importantly, we found that berberine did not exhibit toxicity to nonneoplastic human prostate epithelial cells under the conditions used, except for a moderate reduction in cell viability at higher concentrations when cells were treated in vitro for an extended period of time. In conclusion, the results of the present study indicate that berberine inhibits proliferation and induces G1-phase arrest and apoptosis in human prostate cancer cells but not in normal human prostate epithelial cells. In addition, we provide mechanistic evidence that berberine-induced apoptosis in prostate carcinoma cells, particularly hormone-refractory prostate carcinoma cells, is mediated through enhanced expression of Bax, disruption of the mitochondrial membrane potential, and activation of caspase-3.

Ursolic acid is a component of many herbs that seems to have a protective effect versus inflammation and its various ramifications

When these cell cultures were treated with red clover isoflavones, the androgenic effects of DHEA were reversed. "Something is happening in the prostate tissue microenvironment that is illustrating a potential cancer prevention effect from this supplement," said Arnold. Red clover isoflavones may modify androgenic effects in the prostate but much more work in the laboratory and clinic is needed to validate these effects.

Complementary and alternative medicine (CAM) and complementary and integrative medicine (CIM) are therapies of proven or unproven efficacy that have been used to promote wellness, to manage symptoms associated with cancer and its treatment or to treat cancer. When properly combined with standard cancer treatments, some complementary therapies can enhance wellness and quality of life, but others may be harmful during or after treatment for cancer. Most, but not all, are natural products.

"Maté consumption plays a significant and independent role in the development of upper aeodigestive tract cancers," and "Maté drinking should be considered one of the risk factors for cancer of the neck and head."
