For little blocked noses For those little blocked noses that find traditional Olbas Oil just a bit too powerful, there's Olbas for Children, a gentle decongestant formulation to relieve congestion in even the smallest noses of the family – from as young as 3 months old. Just add a few drops of Olbas for Children to a tissue or hanky (placed out of child's reach) for soothing but effective blocked nose relief – even at night. *Always read the label
