Rosemary (Rosmarinus officinalis Linn.) is a common household plant grown in many parts of the world. Rosemary is used for flavoring food, a beverage drink, as well as in cosmetics. In folk medicine, rosemary is used as an antispasmodic in renal colic and for dysmenorrhoea, in relieving respiratory disorders and to stimulate growth of hair. Extracts of rosemary relax smooth muscles of trachea and intestine, and have liver protective and anti-tumor activity. Adding a dash of rosemary extract to ground beef reduces the amount of cancer -causing compounds created during the cooking process. When antioxidants extracted from rosemary were added to ground beef, hamburgers contained smaller amounts of heterocyclic amines, or HCAs, carcinogenic compounds that form when muscle meats like beef, pork and poultry are cooked at high temperatures.
