Alfalfa: Medicago sativa: Originating in Central Asia, with some of its first evidence of cultivation in Iran, this herb has been a component in traditional medicine and folk remedies for hundreds of years. Alfalfa is more than the name of one of the “Little Rascals”! It contains calcium, vitamins A, C and D and is also a source of protein. Studies show alfalfa can also help lower cholesterol, improve metabolism and gives the body a healthy dose of antioxidants. Alfalfa is described as having a mild, nutty and crunchy flavour and texture.
