grape seed extract

Abbreviation: GSE
An extract of antioxidant oils isolated from the seeds of grapes (Vitis vinifera) and promoted by alternative and complementary medical practitioners as a potential treatment for coronary artery disease, cancer, and other illnesses produced or worsened by oxidative stresses on body tissues. The extract has been used as a traditional European remedy for diseases of the eyes and skin seems to reduce postoperative swelling faster than placebo. Scientific evidence for its clinical effectiveness is sparse.
