Special Precautions & Warnings:

Children: Wintergreen leaf and oil can be poisonous for children. Taking 4-10 mL of wintergreen oil by mouth can be deadly. Don’t even use wintergreen oil on the skin of children less than 2 years old.

Pregnancy and breast-feeding: Wintergreen is safe in amounts found in food, but there's not enough information to know if it's safe in the larger amounts that are used as medicine. Don’t take it by mouth or put it on your skin, if you are pregnant.

If you are breast-feeding, don’t take wintergreen by mouth or put it on your skin. Wintergreen products might be toxic to nursing infants.

Stomach and intestinal inflammation: Taking wintergreen by mouth might make these conditions worse.

Salicylate or aspirinallergy, asthma, or nasal polyps: Wintergreen might cause an allergic reaction in people who are allergic to aspirin or other salicylate compounds, or have asthma or nasal polyps. Use wintergreen with caution if you have one of these conditions.
