Ginkgo Supplements are used for conditions that seem to be due to reduced blood flow in the brain, especially in older people. These conditions include memory loss, headache, ringing in the ears, vertigo. Some people use it for other problems related to poor blood flow in the body, including leg pain when walking (claudication), and Raynaud's syndrome (a painful response to cold, especially in the fingers and toes). Some people use ginkgo to treat sexual performance problems. It is sometimes used to reverse the sexual performance problems that can accompany taking certain antidepressants called SSRIs.
