All Benefits/Effects/Facts & Information

Garlic is a vegetable that has been used for centuries in alternative medicine for its health benefits. It was originally cultivated in central Asia and the Middle East, but has become widely accessible worldwide. Its effectiveness is due primarily to allicin, a sulfur compound that produces several sulfur-containing metabolites that the body can use.

Garlic (Allium sativum) is a nutrient packed vegetable that may be used medicinally as raw fresh garlic, dried, aged or powdered extract. Supplementation may improve cardiovascular health, physical vitality, brain function, and immunity.

Studies suggest that these sulfur compounds can have cardioprotective properties, and may also help lower cholesterol. Various studies have found that ingestion of a garlic supplement helped to reduce plaque formation in arteries and reduced the risk of cardiovascular disease. Evidence for lowered cholesterol can also be found, but more research is needed to validate this claim. While the differences due to garlic intake were small, the combination of garlic with other treatment and lifestyle changes can produce more significant results.

Garlic has also been found to have certain antibacterial, antiviral, and antifungal properties that can be used to prevent diseases such as colds and yeast infections. Preliminary studies also suggest that garlic may degrade carcinogenic compounds and therefore reduce the risk of developing cancer. Further research must be conducted to confirm these claims.
