Ginkgo Biloba (Vataharini)

About

Ginkgo biloba is a deciduous tree, native to China, that is the sole surviving species of the division Ginkgophyta. It is a long-lived tree, with some specimens known to be over 1,000 years old. The tree has distinctive fan-shaped leaves that turn a vibrant yellow in autumn. It produces small, fleshy, apricot-like fruits that have a strong, unpleasant odor when ripe.

Properties

Ginkgo biloba is characterized by its unique phytochemical profile, including flavonoids (e.g., quercetin, kaempferol) and terpenoids (ginkgolides, bilobalide). These compounds are believed to contribute to its antioxidant and anti-inflammatory effects.

Standardized extracts typically range from 120-240 mg per day, divided into two doses.
