Study links mentholated rubs to infant respiratory distress

A newly published study further backs previous research that found mentholated rubs may cause airway inflammation that can restrict breathing in infants and toddlers.

Doctors at North Carolina's Wake Forest University initiated the study after treating an 18-month-old child that was experiencing breathing problems after Vicks VapoRub was applied under her nose to treat a cold.

To confirm their suspicions that the mentholated rub caused the child's respiratory distress, lead researcher Dr. Bruce K. Rubin and his team performed experiments on ferrets, which have airways similar to human airways.

The research found that mentholated rubs increased mucus production by up to 59% and reduced the ability to clear mucus by 36%.
