i use it on all my children whenever they get sick. and also gift it to family and friends with kids. ive tried different brands but I find this most effective. it is gentle enough to be used even on little babies but can also be used by adults. very helpful especially at night when my kids have trouble sleeping because of terrible cough and colds. clears congested nose and soothes their chests. its is a must have in our medicine kit at home and when travelling. my whole family is very sensitive with any fragrance but this products smells wonderful but mild.
