Garlic (Allium sativum) is a vegetable that can be eaten raw or cooked. It is also sold as a dietary supplement. Garlic contains several sulfur-containing phytochemicals that are metabolized when eaten and can affect cardiovascular health and inflammation.[1] These chemicals include allicin, diallyl disulfide (DADS), diallyl trisulfide (DATS), and S-allylmercaptocysteine (SAMC).
