Grape seed extract reduces inflammation, and contains substances like proanthocyanidins, which help to flush infection and parasites from the body and slow the aging process, according to the Nutritional Supplements website. Proanthocyanidins is also one of the ingredients in red wine that make an occasional glass beneficial, as the substance enhances circulation and can help to relieve impotence or conditions like diabetic neuropathy.
Grape seed extract may help protect the body from parasites, as it is rich in antioxidants. Antioxidants help to shield the body's cells from free radicals, which makes the immune system stronger and reduces the chances of parasite infestation; the Natural News website even asserts that grape seed extract has more antioxidant power than vitamins C and E. Grape seed extract can also be applied topically to a wound to restore the damaged blood vessels and take bacteria and infection from the wound before it has a chance to affect the rest of the body.
An individual infected with parasites could exhibit a number of symptoms, including allergies to several types of food, constant feelings of anxiety or irritability, bloating and pain in the intestinal area. The I Told You I Was Sick website asserts that more than 50 percent of American people are exposed to parasites. These toxins can enter the body by drinking tap water, eating or preparing contaminated meats, or coming in contact with a pet that has parasites.
In addition to grape seed extract's ability to expel parasites, the supplement can also lower blood pressure, as the antioxidants keep blood vessels from being damaged. While animal testing has been conducted to prove that grape seed extract treats hypertension, the University of Maryland asserts that more studies on humans are necessary. Grape seed extract may also reduce the risk of cancer. In a 2004 issue of the Journal of Nutrition, it was reported that grape seed extract, along with a diet rich in soy protein and vegetables could prevent cancer development; when the extract was given to rats, the result was a 50-percent reduction in tumor development.
The Web MD website asserts that no one knows for sure what a safe dosage of grape seed extract is, but the recommended dosage is between 100 and 300mg a day, as these are the measurements prescribed in European medical practices. However, some individuals may need more or less of the supplement depending on nutritional needs and health goals.
