Genus & Species: Ginkgo biloba
Common Names: Maidenhair Tree
Overview: Ginkgo biloba is a large deciduous tree that garners quite a bit of attention from biologists and herbalists alike. Regarded as a “living fossil”, this unique elder-plant has existed for 270 million years without any changes. Amazingly, it has no living relatives in existence.  The individual trees are also known for their incredibly long life span, exemplified by the thriving 1,400 year old ginkgo found at a Buddhist temple in China. Fittingly, ginkgo’s most common use in herbal medicine is as an agent to improve symptoms of Alzheimer’s and impaired circulation in the elderly. [2,3] Modern clinical studies have demonstrated that extracts of ginkgo leaf specifically improve cerebral blood flow and reduce depression, tinnitus, and memory loss. 
Therapeutic Properties: Nootropic, circulatory stimulant and tonic, anti-inflammatory, vasodilator, antioxidant, antispasmodic, anti-depressant, antiplatelet, gentle stimulant, astringent. [3,4]
Typical Uses: Ginkgo is most often taken internally, either as a standardized extract or as a tea. Both forms facilitate ginkgo’s effect as a cognitive enhancer and general circulatory tonic. It’s also best to use the herb internally if you’re hoping to experience its mood lifting, energizing, and antioxidant benefits.  However, if there is a specific part of the body that would benefit from increased circulation, then a topical application might be your best bet. This can be done by infusing ginkgo leaves into a carrier oil and then applying it to the area of concern a couple of times throughout the day.
