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

Ginkgo biloba is a natural supplement that has been used for centuries to improve memory, concentration, and mental alertness. It's also believed to help reduce inflammation in the brain. Studies have shown that it can be beneficial for treating mild cognitive impairment, but it's not clear if it helps with more serious conditions like Alzheimer's disease. Overall, there is some evidence that ginkgo may be helpful for improving mental performance, but more research is needed to determine its effectiveness for specific conditions.
