Introduction Herbal therapies have been part of traditional treatments for centuries.
Herbal therapies have important biological activities and are in wide use for numerous diseases.
Ginkgo is used to protect neurological function, garlic to inhibit abnormal platelet aggregation, and saw palmetto is used to ease symptoms of noncancerous prostate enlargement. All of these are Chinese herbs except Serenoa repens , an extract of the American dwarf palm, or saw palmetto. PC-SPES also contains compounds that may enhance immune cell action and components that interfere with testosterone metabolism and prevent testosterone from binding to prostate cells. Hara et al., Eur. Scutellaria therefore seems to be an essential herb in the PC-SPES combination, probably due to the presence of baicalein.
