Many European doctors and a growing number of U.S. doctors use Ginkgo biloba to treat tinnitus, and a few good trials suggest that this herb may lower the perceived loudness. The advice is to use a Ginkgo product that contains 24% flavone glycosides or standardized extract. According to several health experts, the recommended dose varies from 120 to 240 mg daily of the standard Ginkgo in divided doses. Start with the lower dose, and if not effective, increase gradually to the higher dose. Ginkgo biloba improves blood flow and nerve function, and is supposed to be quite effective for tinnitus when the cause is poor circulation, but use with caution if taking a blood thinner or if you have a blood disorder. After starting this regimen of Ginkgo, not only will your thinking be sharper within 3 to 10 days, but within 6 weeks your tinnitus should be relieved, says Dr. Kane. Once relief is obtained, lower the dose to a maintenance dose of 40 to 60 mg daily .
A high number of tinnitus sufferers are deficient in B-12, and Emily A. Kane, naturopathic doctor and licensed acupuncturist, recommends a daily dose of 2,000 mcg of B-12 for one month, followed by a dose of 1,000 mcg daily, if needed. Studies indicate that nutritional supplements can reduce the severity and incidences of tinnitus. Dr. Michael Seidman, MD, Director of the Henry Ford Health System, Department of Otolaryngology, Tinnitus Clinic, in Bloomfield, Michigan, suggests a smorgasbord of antioxidant nutrients: vinpocetine, Ginkgo biloba, ipriflavone, arginine, alpha lipoic acid, zinc, vitamin A, n-acetylcysteine, magnesium, melatonin, Chinese herbs, B vitamins and garlic. Other sources list additional supplements: vitamin E, C, zinc, and choline, to help with both tinnitus and hearing loss.
