• Curcumin Exhibits Chemopreventive and Chemotherapeutic Effects in Human Colorectal Cancer Cells. Similarly the results from a test-tube study suggest that curcumin may hold potential as a therapeutic agent in the treatment of colon cancer
• An animal study shows that turmeric holds potential to prevent rheumatoid arthritis. The treated animals were found to have significantly reduced cartilage destruction and bone mineral density destruction.
• In a study involving animals exposed to chronic stress, treatment with curcumin was found to reverse the negative effects on behavior and physiology brought on by the chronic stress
• A preliminary study suggested that curcumin may be an effective agent in the prevention of metastasis.
• Curcuminoids given in a clinical study showed that they may have a role in the treatment of Alzheimer's disease
• Curcumin may be an effective maintenance therapy for patients with quiescent ulcerative colitis as shown in an elaborate clinical study.

Phytoestrogens

• Epidemiological studies indicate that dietary phytoestrogen intake may reduce the risk of colorectal cancer, and similarly for breast cancer in another study.
• These results suggest that in men with certain genotypes, high intake of dietary phytoestrogens may be associated with a reduced risk of prostate cancer.

Green Tea

• A small clinical study indicates that daily consumption of green tea may protect against the risk for cardiovascular disease by improving blood lipid levels.
• A study of diabetic animals, showed that green tea extract can reduce the risk of cardiovascular disease- with a significant improvement in lipid metabolism.
• A study suggests that EGCG (from green tea) given to mice could potentially improve glucose tolerance.
• A test tube study shows that green tea exerts antioxidant action.
• In a case control study, regular consumption of green tea protects against breast cancer

Ginger

• An animal study showed that treatment with ginger was found to reduce diabetes-induced nephropathies.
• Ginger has shown efficacy for prevention of nausea and borderline significance to prevention of vomiting after gynecological laparoscopy at 6 hour post operation

Garlic

• In a single-blind, placebo-controlled study involving 150 hyperlipidemic patients, results indicate that supplementation with garlic may exert a beneficial effect on lipid profiles.
• In a pilot study involving 6 subjects with marginally elevated blood pressure (140/90 mm Hg), supplementation with garlic and vitamin C was found to reduce blood pressure to reference ranges.

Miscellaneous

• In a randomized, double-blind, placebo-controlled study involving 52 patients with type II diabetes, supplementation with the herbal medicine, milk thistle seed extract was found to improve blood sugar profile.
• Review data from pilot studies and trials investigating the effects of polyphenolic phytochemicals such as epigallocatechin (EGCG) from tea, curcumin from turmeric, and soy isoflavones, in the prevention of cancer and warrants further research to study their use as alternative chemotherapy agents
• Spearmint tea can be an alternative to antiandrogenic treatment for mild hirsutism (excessive hair growth) in women
• In a study examining epidemiological and biological data, results indicate that supplementation with ginkgo biloba may exert protective effects against ovarian cancer
• In a case-control study involving 1,434 breast cancer cases and 1,440 controls, dietary flavonoid intake was associated with a reduced risk of breast cancer in postmenopausal women
