Grape Seed Extract

Grape seed extract, which is made from the seeds of wine grapes, is promoted as a dietary supplement for various conditions, including venous insufficiency (when veins have problems sending blood from the legs back to the heart), promoting wound healing, and reducing inflammation. Grape seed extract contains proanthocyanidins, which have been studied for a variety of health conditions. There are some well-controlled studies of people using grape seed extract for certain health conditions. Some studies suggest that grape seed extract might help with symptoms of chronic venous insufficiency and with eye stress from glare.
