Grape Seed Extract

Scientific Name: Vitis vinifera

Grape Seed Extract Information

The medicinal and nutritional value of grapes (Vitis vinifera) has been heralded for thousands of years. Grape leaves were traditionally used to stop bleeding, inflammation, and pain, such as the kind brought on by hemorrhoids. Unripe grapes were used to treat sore throats and dried grapes (raisins) were used to heal consumption, constipation, and thirst. The round, ripe, sweet grapes, were used to treat a range of health problems including cancer, cholera, smallpox, nausea, eye infections, and skin, kidney, and liver diseases. Researchers are now discovering that most of the healthful properties of grapes may actually come from the seeds themselves. Among other beneficial effects, the active compounds in grape seed are believed to have antioxidant properties. A recent study found that supplementation with grape seed extract substantially increased levels of antioxidants in the blood. Antioxidants found in grape seeds can neutralize free radicals and may reduce or even help prevent some of the damage they cause. Today, professional herbalists use standardized extracts of grape seed to treat a range of health problems related to free radical damage, including heart disease and cancer. Flavonoids found in red wine have been shown to inhibit the oxidation of LDL ("bad") cholesterol. (LDL oxidation can lead to hardening of the arteries or atherosclerosis). If it is indeed the flavonoids contributing to heart protection, then grape seed extracts offer an important alternative to alcohol, particularly given the down sides of drinking alcohol). It is also important to note that the use of alcohol is not advocated by the American Heart Association and other organizations because of the potential for addiction and the other serious repercussions such as motor vehicle accidents and the development of hypertension, liver disease, breast cancer, and weight gain.

Grape Seed Extract Benefits

  • Combination of grape seed extract and chromium effective in reducing total and LDL ("bad") cholesterol

  • Also effective in preventing damage to human liver cells caused by chemotherapy medications
  • Also recommended for a variety of circulatory ailments (including varicose veins and chronic venous insufficiency) May help improve night vision and photophobia (sensitivity to light) as well.

Grape Seed Extract Nutrient Content

Vitamin E, flavonoids, linoleic acid, and compounds called procyanidins (also known as condensed tannins, pycnogenols, and oligomeric proanthocyanidins or OPCs) are highly concentrated in grape seeds. These healthful compounds can also be found in lower concentrations in the skin of the grape. Procyanidins are also found in grape juice and wine, but in lower concentrations.
