Benefits of Garlic in Heart Disease
Written by Gloria Tsang, RD

Numerous clinical trials have looked at the role and benefits of garlic supplements in heart disease. Many of these randomized studies showed positive benefits of garlic in heart disease: in particular, lowering total cholesterol, LDL cholesterol (the Bad cholesterol) and triglycerides (Also Read: How to lower Triglycerides?). A few small randomized trials also suggested the benefits of garlic in the prevention of platelet aggregation and thrombosis (the formation of plaques in the blood). Another study also showed that aged garlic extracts lowered high blood pressure. Most of these studies are relatively short-term, therefore we do not know if the positive benefits of garlic will last more than 3 months. Please also note that there were a number of studies showing conflicting results.

The American Dietetic Association suggested that in order to obtain the potential health benefits of garlic, one must take 600 - 900mg (about 1 fresh clove) per day.

Some studies looked at the potential benefits of garlic in cancer prevention. Some suggested that garlic inhibited the development and progression of breast, colon, stomach, esophagus, prostate and skin cancers in test tubes and in animals.

Other studies also showed that garlic exhibits antibiotic and antifungal effects.
