Ginkgo is one of the most researched herbs in history, and medical evidence points to its many health benefits. It has been used for centuries in Chinese herbal medicine, especially the gingko leaves and seeds.

Ginkgo has two groups of active substances, flavonoids and terpene lactones, including ginkgolides A, B, and C, bilobalide, quercetin, and kaempferol. The ginkgolides have been shown to control allergic inflammation, anaphylactic shock and asthma.

The standardized ginkgo biloba extract is obtained from the gingko leaves and is used for its medicinal properties.
