Rosemary is a member of the mint family. Its common name derives from Latin and translates as “dew of the sea,” because it thrives close to the coast in dryer areas throughout the Mediterranean. It was used as a spice and folk medicine by Egyptians, Greeks, and Latin cultures. While rosemary contains a range of health-supporting polyphenols, including carnosol, carnosic acid, and rosmarinic acid, our main interest was in a triterpene in rosemary called ursolic acid, which supports muscle performance.
