Radishes are edible root vegetables of the Brassicaceae family and are cousins of mustard and cabbage. They have a mild to hot peppery flavor and crunchy texture. Radishes owe their sharp flavor to the various chemical compounds produced by the plants, including glucosinolate, myrosinase, and isothiocyanate. They are sometimes grown as companion plants and suffer from few pests and diseases, thus germinate quickly and grow rapidly. Radishes are usually grown as annuals and are harvested before they flower. Flowers bear white or lilac-veined petals. Radishes range in shape from spherical to long and cylindrical or tapered, and the outside skin can be white, yellow, pink, red, purple, or black.

Radishes are believed to originate in China, but have been cultivated throughout the world for thousands of years. Ancient records note “models of turnips, beets, and radishes were dedicated to Apollo in the temple of Delphi.” Radishes were one of the first seeds brought over with colonists to the Americas. Today, many cultures honor radishes in celebrations around the world.

Radishes are a very good source of vitamin C, which may help fight disease and rescue healthy cells from an onslaught of destructive free radicals. They can be used to help relieve stomachaches, to facilitate digestion, elimination of excess water and to regulate blood pressure. In the past, radishes were used in treatment of kidney stones, intestinal parasites and bad skin.
