Protective effect found for ginkgo against radiation damage

ginko leavesA report published in the October 11, 2009 issue of the International Journal of Low Radiation added evidence to a protective effect for Ginkgo biloba against radiation damage. Ginkgo biloba is a tree species whose leaves have been used for centuries in Chinese medicine. Ginkgo leaf extract contains antioxidant compounds called ginkgolides and bilobalides which help scavenge free radicals that attack nearly all components of the cell, including DNA.

The researchers found a significant dose-dependent reduction in apoptotic cells among those treated with ginkgo. While radiation-induced apoptosis (cell death) occurred in nearly one third of irradiated cells not treated with ginkgo, the number declined to 5 percent or less in cells treated with the herb.


Editor’s Note: Gingko biloba has also been found to help preserve vision for those with eye diseases such as macular degeneration, glaucoma and diabetic retinopathy. For more related information, go to
