Goji berry-also called wolfberry, gou qi, zi, red diamaon, desert thorn, the Duke of Argyle's tea plant, or Lycium barbarum-is a sweet fruit that has proven itself to be powerful against disease. Goji berry is an ancient Chinese fruit that looks like a red raisin & contains high levels of the health-promoting antioxidant (free-radical fighter) zeaxanthin. Free radicals are molecules with an unpaired electron that are constantly in search of molecules in our bodies to bond with, resulting in DNA damage & a cascade of deleterious reactions that can lead to cancer & heart disease, making us sicker, weaker, & more vulnerable. Goji berry's antioxidants act as search-&-destroy missiles against oxidative stress caused by free radicals.
