The huge leaves can sometimes be two feet long and six inches wide. The herb is widely cultivated for its root, which is dug up in the fall.

Volatile oils and isothiocyanates in the root may have mild antibiotic properties.
Traditional Uses
Today, horseradish is a much undervalued herbal medicine having many healing properties. It has the ability to stimulate the digestion, promote sweating thereby lowering fevers, loosen phlegm and move it out of the system, and rid the body of many harmful organisms. It is especially effective for colds and bronchitis, and urinary or gastrointestinal infections. Ground fresh horseradish mixed with a little honey and added to a cup of hot water is a time-honored cough remedy.
It is also effective in strengthening the stomach, but it does contain certain oils that can irritate stomach ulcers.
When horseradish is crushed, a component called sinigrin produces allyl isothiocyanate, an antibiotic substance, making it a good remedy for respiratory and urinary tract infections.
A sandwich with freshly grated root is a home remedy for hay fever. The large leaves are often used as an addition to salads.
Externally, a poultice can be used to soothe chilblains. The herb is a good rubefacient, stimulating blood flow and bringing it to the surface of the skin and turning it red, necessary in healing. However, care must be taken not to do more damage to the flesh as it can cause blistering if not handled properly. This gentle action is beneficial for relieving joint and muscle pain by creating warmth and stimulating circulation in the area. It acts as a counterirritant, which interferes with the transmission of pain messages from peripheral nerves to the brain.
A tea can be made from the solution remaining after grated horseradish has steeped in vinegar for a week. This can also be used as a condiment.
Horseradish is also used as a water purifier.
