Ginkgo Biloba has been widely studied for its potential benefits regarding a variety of conditions and ailments, including memory problems, dementia, fatigue, asthma, tinnitus, peripheral artery disease and other circulatory problems. And it has now become one of the best-selling herbal supplements on the market in the United States and in Europe. Clinical research suggests that Ginkgo Biloba increases blood flow to the brain. And researchers believe it is this increased circulation that helps enhance memory. Gingko Biloba may effectively improve overall cognitive function, especially in older adults. However, a six-year clinical study suggests that it doesn't slow age-related memory loss associated with mild cognitive impairment, dementia or Alzheimer's disease. While Ginkgo Biloba may not be the "miracle memory herb" researchers hoped for, experts say they've witnessed effective improvements in both memory and cognitive function in patients who regularly use Gingko supplements. However, there are a number of side effects to be aware of, such as headache, nausea, upset stomach, dizziness or allergic skin reactions. Ginkgo may also impact the effectiveness of some prescription drugs including anticonvulsant and antidepressant medications. Ginkgo also contains flavonoids and terpenoids, both powerful antioxidants that protect human cells from the effects of free radicals, which help protect against cancer, cardiovascular disease and other age-related diseases. However, Ginkgo is believed to have blood-thinning properties, so if you take blood thinners, exercise caution. These potential interactions and risks underscore the importance of talking with your health care provider before using any type of herbal supplement.
