The radish is a type of vegetable, which is believed to have originated in western Asia, but is now cultivated worldwide. Many cultures use radish as a food, either alone or added to salads.

In traditional Chinese medicine, radish seeds are an important component of many herbal remedies. The seeds of the radish are gathered at the start of the summer and dried in the sun. They can be used either raw or after being parched, and can be consumed whole, sliced, grounded into powder or crushed into a type of juice.

Radish seeds have pungent, sweet and neutral properties, according to the principles of traditional Chinese medicine, and are affiliated with the Spleen, Stomach and Lung meridians. The two main functions of radish seed are to eliminate food retention, and to move down qi and resolve phlegm. Radish is often used as a digestive aid to treat conditions ranging from abdominal pain to acid reflux, abdominal distention and diarrhea. Radish seeds are also used to treat coughs accompanied by large amounts of phlegm, and asthma. The German Commission E has approved radish to treat peptic disorders and catarrhs of the upper respiratory tract.
