An essential oil taken from the small, brownish-white Chinese ginkgo nut, which acts as a natural antibiotic against many pathogenic bacteria. Ginkgo biloba contains flavonoid glycosides, proanthocyanidins, and terpene derivatives—a collection of intensely potent antioxidants. It is well known for its ability to improve cognitive functions, but for more than 5,000 years its powerful antioxidant properties have been used to fight the free radicals that damage cell walls and cause premature aging. Ginkgo also works to dilate micro-capillaries in the circulatory system, which increases blood circulation to improve skin’s health.
