Application of Grape seed extract

Oct 22，2019

Grape seed extract is an industrial derivative of whole grape seeds. The extract contains proanthocyanidins.Grape seed extract quality is measured by the content of procyanidins which are formed from proanthocyanidins.Generally, grape seed extract quality contains 95% procyanidins, but potency varies among products. Eating foods or beverages high in procyanidin results in the sensation of the mouth puckering and dehydration, otherwise known as astringency, as felt after certain alcoholic drinks.

Application

Since ancient Greece people have used grapes, grape leaves, and sap for health purposes. Grape seed extract was developed in the 1970s.

Today, grape seed extract is used as a dietary supplement for various conditions, including for venous insufficiency (when veins have problems sending blood from the legs back to the heart), to promote wound healing, and to reduce inflammation.

Grape seed extract contains the antioxidant compound oligomeric proanthocyanidin (OPC), which has been studied for a variety of health conditions.

OPCs are found in extracts of grape skin and seeds, which are by-products of the wine industry. Grape seed extract is available in capsules and tablets and as a liquid.

Correlational research

Some studies suggest that compounds in grape seed extract may reduce edema (swelling) and help with symptoms of chronic venous insufficiency, but the evidence isn’t strong.

Grape seed extract may have some heart benefits, including lowering systolic blood pressure and heart rate. The lower heart rate may cause the decrease in systolic blood pressure. The extract had no effect on lipid levels such as cholesterol or C-reactive protein, an indication of inflammation in your arteries.

The National Center for Complementary and Integrative Health (NCCIH) is supporting preliminary research on grape seed extract for Alzheimer’s disease and also for hereditary hemochromatosis, when the body’s iron levels are too high. The National Cancer Institute is supporting preliminary studies on grape seed extract for preventing prostate, lung, and colon cancer.

About Safety

Grape seed extract is generally well tolerated when taken in moderate amounts. It has been tested safely for up to 14 weeks in studies of people. It’s possibly unsafe if you have a bleeding disorder or are going to have surgery or if you take anticoagulants (blood thinners), such as warfarin or aspirin.

Keep in Mind

Tell all your health care providers about any complementary or integrative health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
