Horseradish

How does Horseradish work?

Horseradish might help fight bacteria and stop spasms.

Are there safety concerns?

Horseradish is possibly safe for most people when used by mouth in medicinal amounts, but it contains substances that are 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, and low thyroid.

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.

Horseradish is UNSAFE when used in children less than four years of age or in pregnant or breast-feeding women.

Do not use horseradish if:
  • You have a kidney disorder.
  • You have low thyroid (hypothyroidism).
  • You have a digestive tract problem such as stomach or intestinal ulcers, inflammatory bowel disease, infections, or other conditions.
