Ginkgo biloba is an herbal supplement made from the leaves of the Ginkgo tree, also known as the maidenhair tree. Ginkgo trees are native to China but are now grown worldwide. Ginkgo biloba is categorized as “nootropic,” meaning it’s thought by some to be a cognitive enhancer (related to conscious intellectual activity such as thinking, memory, and reasoning). It is prescribed as a memory and concentration booster in many countries and is widely available as an over-the-counter herbal supplement in the US. Ginkgo is thought to increase blood supply by dilating blood vessels, reducing blood viscosity (thickness), affecting neurotransmitters, and reducing free radicals . For healthy adults, Ginkgo biloba appears to be safe when taken orally in moderate amounts.
