Using oils for congestion is something I do regularly in our household. Whether its allergies or seasonal threats I have oils to the rescue. A congestion blend is a natural blend of Laurel Leaf, Eucalyptus, Peppermint, Melaleuca, Lemon, Cardamom, Ravintsara Leaf, and Ravensara Leaf essential oils.
I replaced the other toxic chest rubs with oils noted above. I rub on my families chest, feet, back when congested or coughing. I also diffuse such blends for these reasons too. It helps maintain the feeling of clear airways and easy breathing.
