Andrew is 64 years old. He has type 2 diabetes mellitus, chronic stable angina, dyslipidemia, and he likes smoking. He is feeling pain in his right upper thigh while walking around the block. The pain has become intolerable, but if he stops walking, it feels better within minutes. He comes to a pharmacy to look for an herbal remedy that could improve his circulation to make him walk better. He is considering taking GINKGO, which is one of the few plants with double-blind, placebo-controlled trials that support its use. A meta-analysis of eight trials showed a 47% improvement. It involved 385 patients taking ginkgo standardized extract 160 milligrams per day for 6 months. They reported a pain-free walking distance of 34 meters.
