How does Horseradish work?

Horseradish might help fight bacteria and stop spasms.

Are there safety concerns?

Horseradish root is LIKELY SAFE when taken by mouth in food amounts. It is POSSIBLY SAFE for most people when taken by mouth in medicinal amounts. However, it contains mustard oil, which is extremely irritating to the lining of the mouth, throat, nose, digestive system, and urinary tract. Horseradish can cause side effects including stomach upset, bloody vomiting, and diarrhea. It may also slow down the activity of the thyroid gland.

When used on the skin, horseradish is POSSIBLY SAFE when preparations containing 2% mustard oil or less are used, but it can cause skin irritation and allergic reactions.

Special Precautions & Warnings:

Children less than 4 years old: Horseradish is LIKELY UNSAFE in young children when taken by mouth because it can cause digestive tract problems.

Pregnancy and breast-feeding: It's LIKELY UNSAFE to take horseradish by mouth in large amounts if you are pregnant or breast-feeding. Horseradish contains mustard oil, which can be toxic and irritating. Horseradish tincture is also LIKELY UNSAFE when used regularly or in large amounts because it might cause a miscarriage.

Stomach or intestinal ulcers, inflammatory bowel disease, infections or other digestive tract conditions: Horseradish can irritate the digestive tract. Don't use horseradish if you have any of these conditions.

Underactive thyroid gland (hypothyroidism): There is concern that using horseradish might make this condition worse.

Kidney problems: There is concern that horseradish might increase urine flow. This could be a problem for people with kidney disorders. Avoid using horseradish if you have kidney problems.
