传统用途
The ginkgo tree is a living fossil — 270 million years old. In TCM, the seed (Bai Guo) is used more than the leaf. Seeds astringe the lungs, stop wheezing, and reduce vaginal discharge. The leaf extract is primarily a modern Western application developed from the 1960s onward.
现代研究
Over 5,700 studies. The most studied herbal supplement for cognitive function. Active compounds: ginkgolides (PAF antagonists improving circulation) and bilobalide (neuroprotective). Evidence is strongest for existing cognitive impairment rather than prevention in healthy adults.
