Ginkgo Biloba Supplement Does Not Improve Cognitive Impairment In MS Patients

A new study that followed up on earlier more promising research has found that the Chinese herbal supplement Ginkgo biloba does not improve cognitive function in multiple sclerosis patients. Between 40 and 60 percent of MS patients have memory problems, lower mental processing speed and reduced executive brain skills. Participants in the placebo-controlled study took 120 mg of Ginkgo biloba twice a day. The U.S. researchers acknowledged that participants were treated for only 12 weeks – perhaps not long enough to modify the disease. They said it is possible that Ginkgo may improve cognitive function if administered earlier in the MS process.
