Ginkgo Biloba Mode of Action
Ginkgo Biloba leaves contain two phytochemical compounds that are believed to provide benefits: flavonoids (plant-based antioxidants) and terpenoids (1). The leaves of this tree contain as many as 20 different flavonoids (2).
The three most abundant flavonoids are quercetin, kaempferol, and isorhamnetin (1). Quercetin is a molecule that is one of the most abundant flavonoids found in most people’s diets (3). Quercetin also has anti-inflammatory and anti-allergy effects (3). Isorhamnetin may support a healthy cardiovascular system (5) and is commonly found in onions (6). Kaempferol, due to its capability of moderating oxidative stress, is showing promise in preliminary research regarding anti-oxidants (7).
The terpenoids have two forms: ginkgolides and bilobalides (1). Ginkgolides A, B, and C may help reduce inflammation (8)(9). Bilobalides are protective for the nervous system, especially for neurons (10) and Bilobalide may help reduce inflammation as well (11).
