You can dab a drop of oil on the inside of your mask to help open airways and breathe easier within your mask. doTERRA has an oil blend called Breathe Respiratory Blend that includes Laurel Leaf, Eucalyptus Leaf, Peppermint Plant, Melaleuca Leaf, Lemon Peel, Cardamom Seed, Ravintsara Leaf, Ravensara Leaf essential oils. I was also stunned to find a PubMed Study showing Geranium and Lemon together may block the ACE-2 Receptors from binding with the COVID virus should you be exposed. https://pubmed.ncbi.nlm.nih.gov/32575476/ You could use each oil separate but I like the Align Centering Blend as it has Bergamot, Coriander, Marjoram, Peppermint, Geranium, Basil, Jasmine absolute, and Rose essential oils in a base of Fractionated Coconut Oil. So I dab a drop of Breathe on the inside and a dab of Align on the outside of my mask. What about you? Add these to your arsenal now.
