The beet (Beta vulgaris) is a plant in the Chenopodiaceae family which is now included in Amaranthaceae family. It is best known in its numerous cultivated varieties, the most well known of which is the purple root vegetable known as the beetroot or garden beet. Beta vulgaris is a herbaceous biennial or, rarely, perennial plant with leafy stems growing to 1–2 m tall. The roots and leaves of the beet have been used in folk medicine to treat a wide variety of ailments. Ancient Romans used beetroot as a treatment for fevers and constipation, amongst other ailments. Apicius in De re coquinaria gives five recipes for soups to be given as a laxative, three of which feature the root of beet. Hippocrates advocated the use of beet leaves as binding for wounds.
