What Is Grape Seed Extract?
The seeds used to make grape seed extract come from Vitis vinifera, the wild grape from which most wine grapes originate. This species is native to the Mediterranean region, central Europe, and Southwestern Asia around the Caspian Sea, but its use in winemaking and medicine first began around the Caspian Sea and moved westward.
To make grape seed extract, manufacturers press grape seeds to remove the oil, and then dry and pulverize them into a concentrated extract that they form into a tablet, capsule, or liquid.
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.
