Ginkgo biloba, commonly known as maidenhair tree, is a herbal supplement derived from the leaves of the Ginkgo tree. In many nations, it is prescribed to improve memory and focus, and in the US, it is commonly sold as an over-the-counter herbal medication. Originally from China, ginkgo trees are now planted all over the world.

Ginkgo biloba is a "nootropic," which means that some people believe it to be a cognitive booster (related to conscious intellectual activity such as thinking, memory, and reasoning).

By widening blood vessels, decreasing blood viscosity (thickness), altering neurotransmitters, and slashing free radicals, ginkgo is thought to enhance blood flow. Ginkgo biloba appears to be safe when taken orally in modest doses by healthy adults. 

The leaves were utilized to cure respiratory issues, cardiovascular issues, and brain disorders. Cough, fever, diarrhea, toothaches, and even gonorrhea were treated with ginkgo nuts. Traditional Chinese medicine has used dried and powdered ginkgo biloba leaves for thousands of years.

Tea was also brewed using the dried ginkgo leaves. Ginkgo extract liquid drops and ginkgo biloba tablets are now available in health food stores.

Modern research mostly concentrates on ginkgo extract, which is derived from the leaves, even though its leaves and seeds are frequently utilized in traditional Chinese medicine.

The majority of the health benefits and uses for ginkgo supplements center on improving blood flow and brain function.
