The kernals are known in traditional Chinese medicine as bai guo, Salisburia adiantifolia, white nut, ying hsing and ying xing; the root is designated bai guo gen.
Chinese medicine

Herbal medicine

Patient discussion about ginkgo

Q. Have food supplements like Ginkgo Biloba been proven to delay memory disorders?

A. Many people are interested in the health benefits of food supplements, hoping that natural substances can have the same efficacy as drugs. The answer to this specific question is NO. A recent study that was published after testing 3,000 people has shown no difference between those who took Ginkgo and those who didn’t. There is no food supplement, including Ginkgo Biloba that was scientifically proved to have the capacity to prevent or delay Dementia. Eating Romaine lattice, broccoli, cauliflower, and spinach have shown good results. Fish with Omega 3 have shown good results too.
