  • Soy is a subtropical plant native to southeastern Asia. This member of the pea family (Fabaceae) grows from 1-5 feet tall and forms clusters of 3-5 pods that each contain 2-4 beans. Soy has been a dietary staple in Asian countries for at least 5,000 years. During the Chou dynasty in China (1134-246 B.C.), fermentation techniques were discovered that allowed soy to be prepared in more easily digestible forms such as tempeh, miso, and tamari soy sauce. Tofu was invented in 2nd Century China. Soy was introduced to Europe in the 1700s and to the United States in the 1800s. Large-scale soybean cultivation began in the United States during World War II. Currently, Midwestern U.S. farmers produce about half of the world's supply of soybeans. Soy and components of soy called "isoflavones" have been studied for many health conditions. Isoflavones (such as genistein) are believed to have estrogen-like effects in the body, and as a result, they are sometimes called "phytoestrogens." In laboratory studies, it is not clear if isoflavones stimulate or block the effects of estrogen or both (acting as "mixed receptor agonists/antagonists").
  • Protein-bound polysaccharide (PSK) has been used in traditional Chinese medicine (TCM) since the Ming Dynasty of China. In the 1980s, the Japanese government approved the use of PSK for treating several types of cancers. By 1984, it ranked 19th on the list of the world's most commercially successful drugs with annual sales of $255 million. PSK is obtained from cultured mycelia of the Coriolus versicolor , a mushroom thought to have antimicrobial, antiviral, and antitumor properties. PSK extracts are available for clinical use in Japan, where it is widely used for cancer immunochemotherapy. In Japan, PSK is currently used as a cancer treatment, in conjunction with surgery, chemotherapy, and/or radiation. Its active ingredient can be administered as a tea or in oral capsule form. In the United States, a similar product is labeled simply Coriolus versicolor extract. Coriolus versicolor is available in limited supply in U.S. markets. In Japan, PSK is currently the best-selling cancer medicine.
  • Ginkgo biloba has been used medicinally for thousands of years. Today, it is one of the top selling herbs in the United States. Ginkgo is used for the treatment of numerous conditions, many of which are under scientific investigation. Available evidence demonstrates ginkgo's efficacy in the management of intermittent claudication, Alzheimer's/multi-infarct dementia, and "cerebral insufficiency" (a syndrome thought to be secondary to atherosclerotic disease, characterized by impaired concentration, confusion, decreased physical performance, fatigue, headache, dizziness, depression, and anxiety). Although not definitive, there is promising early evidence favoring the use of ginkgo for memory enhancement in healthy subjects, altitude (mountain) sickness, symptoms of premenstrual syndrome (PMS), and reduction of chemotherapy-induced end-organ vascular damage. Although still controversial, a recent large trial has shifted the evidence against the use of ginkgo for tinnitus. The herb is generally well tolerated, but due to multiple case reports of bleeding, should be used cautiously in patients on anticoagulant therapy, with known coagulopathy, or prior to some surgical or dental procedures.
  • Numerous controlled trials have examined the effects of oral garlic on serum lipids. Long-term effects on lipids or cardiovascular morbidity and mortality remain unknown. Other preparations (such as enteric-coated or raw garlic) have not been well studied. Small reductions in blood pressure ( Numerous case-control/population-based studies suggest that regular consumption of garlic (particularly unprocessed garlic) may reduce the risk of developing several types of cancer, including gastric and colorectal malignancies. However, prospective controlled trials are lacking. Multiple cases of bleeding have been associated with garlic use, and caution is warranted in patients at risk of bleeding or prior to some surgical/dental procedures. Garlic does not appear to significantly affect blood glucose levels.
