I've heard a lot about a new supplement called ginkgo biloba. Is it safe and effective?

It's widely used in traditional Chinese medicine to treat various conditions, including memory loss, tinnitus, dizziness, headaches, and depression. There is some evidence that it may help improve cognitive function, but the results are mixed. Overall, it appears to be safe when taken at recommended doses, but there have been rare reports of side effects such as headache, nausea, and dizziness. More research is needed before any definitive conclusions can be drawn.
