Side Effects

Side Effects & Safety

When taken by mouth: Radish is LIKELY SAFE for most people when taken in moderate amounts. Taking large amounts of radish can irritate the digestive tract. Some people might be allergic to radish, but this is rare.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough information to know if radish is safe to use while pregnant or breastfeeding. Stay on the safe side and avoid using more than amounts found in foods.

Diabetes: Large amounts of radish might lower blood sugar. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use radish.

Gallstones: Use with caution if you have gallstones. Radish increases bile flow. In people with gallstones, this effect might increase the risk of sudden pain due to a gallstone blocking the bile duct.

Surgery: Large amounts of radish might lower blood sugar levels. There is some concern that it might interfere with blood sugar control during and after surgery. Stop using radish at least 2 weeks before a scheduled surgery.
