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.
