How Grape Works?

The most effective parts of Vitis vinifera are the fruit, fruit skin, leaves and seed. Grape products consist of combination of phenolic compounds including proanthocyanidins, oligomeric proanthocyanidins (OPCs), polyflavan-3-ols and flavonols. Proanthocyanidins are the main factor producing the red color in grapes. Red grape varieties give more antioxidant as compare to blue or white grape mixtures. Red wine contains about 10 times the sum flavonoids of white wine. A relationship seems to exist between total proanthocyanidin content, phenol content and the antioxidant action of grape items. Grape flavonoids have vasodilating, antioxidant, antiplatelet properties and anti-lipoperoxidant activity that might protect from heart disease. Initial confirmation suggests that the delphinidin/cyanidin and proanthocyanidins delphinidin dimer may affect chromosomal damage. Proanthocyanidins may also protect against chemotherapy drug-induced damage to ordinary cells, and minimize liver and kidney harm after overdosage of acetaminophen. Grape seed proanthocyanidins appear to decrease the proliferation of breast cancer, gastric adenocarcinoma, prostate tumor cells and lung disease by increasing cell death and inhibiting cell growth. Grape leaf is believed to have astringent and anti-inflammatory properties. These properties are most prominent in the red leaves. Grape fruit are also thought to have expectorant and laxative properties.

What Are The Side Effects /Adverse Reactions of Grape?

Normally seed extract of grape has no significant side effect. However there are some reported available about abdominal pain, Headache, nausea, sore throat and cough have been reported with usage of grape seed, but these effects may happen at rates similar to placebo.

Lactobacillus Acidophilus - Grape anthocyanins may inhibit the Lactobacillus acidophilus development. Concurrent administration may protect against Lactobacillus acidophilus colonization of the gastrointestinal tract; therefore physicians do not advice its use. Vitamin C - Initial experiments suggest that patients with hypertension, who use both grape seed polyphenols 1000 mg/day and vitamin C 500 mg/day, may have decreased diastolic and systolic blood pressure. However, the possible mechanism of this combination is not known.

How Grape Interacts With Drugs?

Cytochrome P450 1A2 (CYP1A2) Substrates - Interaction rating between grape and cytochrome substrates is moderate, so be careful about this mixture. Grape juice seems to induce cytochrome P450 1A2 (CYP1A2) metabolism and may reduce the plasma levels of CYP1A2 substrates. Phenacetin - Interaction rating between grape and phenacetin is moderate, so be careful about this combination. Grape juice can result in decrease in phenacetin concentration, but not acetaminophen plasma levels. It may reduce the levels by inducing cytochrome P450 1A2 (CYP1A2) metabolism. Warfarin (Coumadin) - Interaction rating between grape powder and warfarin, is moderate so be careful about this mixture. Because of the tocopherol content of grape seed oil, the concomitant usage with warfarin may enhance the warfarin's impacts and the potential bleeding.

Grape seed extract, in form of capsules or tablets, is taken in a dose of 75 to 300 mg every day for three weeks followed by a maintenance dose of 40 to 80 mg every day. In order to treat chronic venous insufficiency, seed extract of grape called proanthocyanidin, should be taken in a range of 150 to 300 mg on daily basis. To relief from ocular stress because of glare, seed extract of grape, called proanthocyanidin, should be used in a range of 200 to 300 mg daily.
