Traditional uses of Ginkgo biloba include the relief of symptoms of: Raynaud's Syndrome - a condition where the blood supply to the fingers and toes is interrupted in response to changes in temperature or emotional stress, causing the skin to turn white and can cause pain, numbness or tingling. This usually affects the fingers and toes. Tinnitus - a condition whereby you hear sounds that are not actually there - you may hear ringing, buzzing or swooshing noises that are not audible to anyone else. They may occur in either or both ears, and may come and go at varying levels.
