I have had tinnitus and dizziness for 2 years intermittently.

The herb Ginkgo biloba works usually better in cases where it comes and it goes. If tinnitus is still there, sometimes it is caused by calcification of the ossicles and ginkgo can do nothing at this point . We must then work differently with the risk that it might not improve. But in your case the possibilities of success with the Ginkgo are high.

See the following for different causes for tinnitus.
