HORSERADISH: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Horseradish (Armoracia rusticana) is a plant. The roots are often used as a condiment and eaten with beef and fish. They are also sometimes used as medicine.

Horseradish might help fight bacteria and stop spasms.

People use horseradish for urinary tract infections (UTIs), colic, gout, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse horseradish with moringa or wasabi. These are not the same.

Side Effects

When taken by mouth: Horseradish root is commonly consumed with foods. It is possibly safe when used as medicine for up to 12 weeks. But it contains mustard oil, which can irritate the lining of the mouth and stomach. When consumed in large amounts, side effects might include stomach upset, bloody vomiting, diarrhea, and fainting.

When applied to the skin: Horseradish is possibly safe when preparations containing 2% mustard oil or less are used. It can cause skin irritation and allergic reactions.
