Tinnitus is a disorder characterized by a ringing sound in the ears that affects an estimated 50 million Americans, according to website HolisticOnline.com. The condition ranges from a minor annoyance that sounds like buzzing, chirping or hissing to a significant sound that can cause sufferers to experience chronic distraction and insomnia. Causes of tinnitus include a blocked blood vessel, a head injury, an infection or exposure to a booming sound, such as an explosion. Herbs have been known to treat tinnitus effectively, according to HolisticOnline.com, but a physician should be consulted before taking them.
Gingko Biloba

HolisticOnline.com recommends taking 120mg extract of ginkgo biloba per day that is standardized to contain 24 percent flavone. Although ginkgo does not effectively treat all tinnitus cases, it is virtually without side effects and has alternative benefits such as improving memory and brain function.
