Clinical Summary
Obtained as a by-product of wine production, grape seeds are ground to produce grape seed oil. Traditionally, grape seed oil and grape seed extract (GSE) have been used as a laxative, antacid, cholagogic agent, to treat burns, ulcers, and as a hand cleanser (1) (2). Studies of grape seed proanthocyanidin extract (GSPE) in mice have shown effectiveness in minimizing cardiotoxicity induced by doxorubicin (15) , cyclosporine (22); and drug-induced nephro- and pulmonary toxicities (3) (23). GSPE also inhibits atherosclerosis (4) (5).
Small human trials have shown possible efficacy in decreasing LDL (6) and increasing total serum antioxidant activity (7). Conclusions from a meta analysis indicate that grape seed extract significantly lowers systolic blood pressure and heart rate, but does not affect lipid or CRP levels (24).
Topical application of GSPE has been shown to accelerate wound contraction and closure (8).
In vitro studies have shown GSPE to have anticancer effects (16) (17) and synergistic effects with doxorubicin (13). Supplementation with grape seed may be associated with decreased risk of hematologic malignancies (21).
But orally administered GSPE was not effective for breast induration following radiotherapy in patients with breast cancer (14).
Purported Uses
- Atherosclerosis
- Burns
- Cancer prevention
- Constipation
- GI disorders
- High cholesterol
- Wound healing
Constituents
- Oligomeric proanthocyanidins (OPC): dimeric, trimeric and tetrameric OPCs, cathechin derivatives, other flavonoids
- Lipids: palmitic, stearic, oleic, linoleic, sitosterol and tocopherols. Phosphatidylserine, phosphatidylinositol, lecithin, cephalin, cerebrosides and phosphatic acid are bound to seed lipoproteins.
- Proteins: leucine, arginine, cystine, phenylalanine, valine
- Tocopherol
- Tannins
(3)
Mechanism of Action
Proanthocyanidins and minor phenolic compounds found in GSPE are also found naturally in many foods including fruits, vegetables, chocolate and tea. People generally consume 460-1000 mg/day of these combined substances (9). GPSE has protective effects on doxorubin-induced cardiotoxicity (3). Cardioprotective effects may be due to its ability to modulate anti-apoptotic genes and modify molecular targets such as DNA damage and repair, lipid peroxidation and intracellular calcium homeostasis (5).
Herb-Drug Interactions
- Cytochrome P450 3A4 substrates: Grape seed extract inhibits CYP3A4 and can affect the intracellular concentration of drugs metabolized by this enzyme (18).
- Warfarin (Coumadin): Due to its anticoagulant effects, grape seed can enhance the activity of warfarin (11) (12) (19).
- UGT (Uridine 5'-diphospho-glucuronosyltransferase) substrates: Grape seed modulates UGT enzymes in vitro and can increase the side effects of drugs metabolized by them (20).
Literature Summary and Critique
Feringa HH, Laskey DA, Dickson JE, Coleman CI. The effect of grape seed extract on cardiovascular risk markers: a meta-analysis of randomized controlled trials.J Am Diet Assoc. 2011 Aug;111(8):1173-81.
Nine randomized controlled trials involving 390 patients were included in this meta analysis. The studies had to report efficacy data on at least one of the following end points: systolic or diastolic blood pressure, heart rate, total cholesterol, low-density or high-density lipoprotein cholesterol, triglycerides, or CRP. Results showed that grape seed extract significantly lowered systolic blood pressure (P=0.02]), and heart rate (P=0.01]). No significant effect on diastolic blood pressure, lipid levels, or CRP was found. Larger randomized, double-blinded trials are warranted to evaluate different dosages of grape seed extract and for longer follow-up periods.

Consumer Information
How It Works
Bottom Line: Grape seed has not been shown to treat or prevent cancer.
Grape Seed Extract is derived from the oil that comes from ground red wine grapes. The extract contains a substance called proanthocyanidin which has antioxidant activities. Proanthocyanidins have also been shown to reduce cholesterol in patients with high cholesterol. Other substances within the grape seed may also help protect teeth from decay.
Purported Uses
- To lower high cholesterol
One study showed a combination of Grape Seed Extract and chromium to be effective at lowering cholesterol levels.
- As an antioxidant
One small study showed Grape Seed Extract to increase antioxidant levels in the blood.
- To treat atherosclerosis
Although studies have shown that substances found within grape seeds may have an effect in reducing the thickening of arteries, further study is needed to determine whether Grape Seed Extract will reduce atherosclerosis in humans.
- As a topical wound treatment
Animal studies have shown a possible effect, but further study is required to determine its effect in humans.
- As a laxative
No scientific evidence supports this use.
- As an antacid
This claim is not supported by research.
- To treat ulcers
There is no evidence to back this claim.
Research Evidence
Cardiovascular Health:
Nine randomized controlled trials involving 390 patients were included in this meta analysis. The studies had to report efficacy data on at least one of the following end points: systolic or diastolic blood pressure, heart rate, total cholesterol, low-density or high-density lipoprotein cholesterol, triglycerides, or CRP. Results showed that grape seed extract significantly lowered systolic blood pressure. No significant effect on diastolic blood pressure, lipid levels, or CRP was found.
Do Not Take If
- You are taking drugs that are substrates of Cytochrome P450 3A4 (Grape seed may increase the risk of side effects of these drugs).
- You are taking Warfarin or other blood thinners (Grape seed can increase the risk of bleeding).
- You are taking drugs that are substrates of UGT (Uridine 5'-diphospho-glucuronosyltransferase) enzymes (grape seed may increase the risk of side effects of these drugs).

acid (A-sid)
A chemical that gives off hydrogen ions in water and forms salts by combining with certain metals. Acids have a sour taste and turn certain dyes red. Some acids made by the body, such as gastric acid, can help organs work the way they should. An example of an acid is hydrochloric acid. Acidity is measured on a scale called the pH scale. On this scale, a value of 7 is neutral, and a pH value of less than 7 to 0 shows increasing acidity.

Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord.
