Ginkgo has been used in alternative medicine as a possibly effective aid in improving mental function or treating anxiety, dementia, leg pain caused by blood circulation problems, premenstrual symptoms, vision problems caused by glaucoma or diabetes, vertigo (dizziness), or a movement disorder (tardive dyskinesia) caused by taking certain antipsychotic drugs.
Ginkgo has also been used to treat seasonal affective disorder, age-related memory loss, asthma, tinnitus (ringing in the ears), high blood pressure, multiple sclerosis, cocaine addiction, or sexual problems caused by taking antidepressants. However, research has shown that ginkgo may not be effective in treating these conditions.
Research has shown that ginkgo is not likely to be effective in treating heart disease.
Other uses not proven with research have included altitude sickness, macular degeneration (age-related vision loss), attention deficit disorder, dyslexia, vitiligo (discolored skin), migraines, bronchitis, digestion problems, urination problems, skin sores, high cholesterol, Raynaud's syndrome, fibromyalgia, chronic fatigue syndrome, blood clots, stroke, and cancer.
