Radish (Raphanus sativum) is a herbaceous plant native from China, belonging to the cruciferous family. The edible part of radish is the root, which has been used since time immemorial for its depurative and sedative properties.

Radish root comes in different shapes, colors and sizes, depending on the variety. It can be round or oblong in shape, while color varies from carmine red to white; and some varieties of radish are characterized by a red color with white streaks.

Its texture is like that of turnips, crunchy, but has a unique sharp-biting and slightly spicy flavor. Depending on the variety, the level of pungency varies from mild to sharp. The green leafy tops are edible and adds a peppery taste to salads.

The more popular radish in Asia is the daikon radish which is shaped almost like the carrot root and are white in color. This variety is typically about 12 to 18 inches in length but can grow up to three feet long! The daikon has firm and crisp texture, and tastes pungent.

Nutritional Benefits of Radish

Radish is rich in vitamins C and B, which are mainly responsible for its anti-inflammatory and sedative properties, respectively. It is also an excellent source of potassium, calcium, iron, copper, sulfur, phosphorous and fiber, while it is very low in calories, virtually devoid of fat and cholesterol.

Radish leaves contain almost six times more vitamin C than its root and are an excellent source of calcium.

To get the maximum nutritional benefits from radish, it is best to consume it when it is young and still small in size, since, as radish gets older, nutrients are drawn from the root (the edible part) to the leaves.

As a member of the cruciferous vegetable family the radish has high content of anti-oxidants and has been used for centuries for its sedative and depurative properties. Below are some health conditions that can benefit from a regular use of radish juice:

Consumption Tips

Due to its strong and pungent taste, some people prefer to mix it with other fruit or vegetable juices, such as carrot or apple juices. Choose and consume young radish, but do not cook them as high heat destroys the high content of vitamin C.

As the leaves continue to draw nutrients from the radish root, storing with the greens attached can only keep for about 3-5 days in the fridge. Without the greens, the radishes can keep for up to four weeks in the fridge.

With some varieties, the skin may be thick and hot so may need to be peeled before consuming.

Cautionary Note

Radish has no known safety issues except that the taste is very pungent.  When eating/juicing black radish, be aware of its skin which can be very hot to the taste.
