Grape seed oil is a substance derived from the leaves of the Vitis vinifera, a plant made up of large vines. Grapes are a type of fruit native to Asia, though Vitis vinifera vines can be found in some regions of Europe and North America today. Before using grape seed oil extract, talk to your medical provider about the benefits and potential risks associated with this natural supplement.
Benefits
Grapes contain a powerful class of antioxidants called oligomeric proanthocyanidin complexes that help protect your cells against oxidative damage. Treatment with grape seed oil extract is purported to help protect your heart by lowering bad or LDL cholesterol and reducing high blood pressure levels; however, additional research in humans is necessary to further support these reported benefits of grape seed oil extract. The use of this supplement may also help reduce excessive swelling, called edema, and chronic venous insufficiency, a condition characterized by swelling, pain and visible veins in the legs. Grape seed oil extract may also help control blood sugar levels, treat hemorrhoids, improve night vision or protect the skin against normal aging; however, health officials with the University of Maryland Medical Center warn that research supporting the use of grape seed oil extract for use in these medical condition is lacking.

Mild side effects have been reported following treatment with grape seed oil extract such as nausea, indigestion, hives, dizziness and headache. Grape seed oil extract may cause dryness or itchiness on your scalp. Certain people may also experience an unusual increase in their blood pressure. Seek care from your medical provider if you experience severe or persistent side effects while taking grape seed oil extract to ensure you receive appropriate care.
