The roots, stems and leaves of leek can be used as medicine to treat respiratory diseases such as cold, fever and sore throat. The leaves and flowers of garlic vine contain organic sulfides such as diallyl disulfide and diallyl trisulfide, so they have garlic fragrance. These two kinds of organic sulfides have many biological activities and are both effective components of garlic oil. In addition, because garlic vine has a strong garlic flavor, it can be used as a substitute for garlic in cooking.
