Herb improves life expectancy in elderly, study finds
The herb Ginkgo biloba appears to extend the lives of older people, but it may not reduce their risk of dementia, according to a new study.French researchers studied 3,534 men and women 65 and older. Those who used the herb were 24% less likely to die over a 13-year period than their peers who didn't take Ginkgo. Ginkgo biloba extract has been marketed and sold to enhance memory.
Researchers found, however, that about 21% of the elderly who took Gingko biloba developed dementia compared with approximately 22% of those on other memory treatments and roughly 15% who were not taking memory enhancers. The study was published in the Journal of the American Geriatrics Society.
