Ginkgo biloba is an herbal supplement associated with several health benefits related to brain function and blood circulation. It may help reduce inflammation and symptoms for conditions like arthritis, IBD, heart disease, and stroke. Ginkgo is also studied for improving cognitive function in dementia and Alzheimer's disease, easing leg pain from poor circulation, relieving PMS symptoms, boosting mood, reducing headaches, improving lung function in asthma, treating schizophrenia symptoms, managing tinnitus, stopping the spread of vitiligo, and aiding recovery from stroke. More research is still needed to confirm all of these benefits.
