Black Goji Berry (Lycium ruthenicum) - 黑枸杞 (He Gou Qi)
A relative of the more commonly known red Goji berries, the Black Goji berries are by contrast only available wild and harvested in the Chinese province of Qinghai.
Black Goji contains the highest concentration of OPC, a group of powerful antioxidant compounds mostly found in blueberries and grape seed. OPC is known to fight damages caused by free radicals. Black Goji berries are also good for preventing further deterioration of myopia and long-sightedness.
Add a small spoon into hot, boiled water. Let steep for 5 minutes before drinking.
