A great video for those who want to enhance their face mask using essential oils. Oils I would recommend which support the respiratory system and breathing would be Eucalyptus oils (Citradora, Smithii, Globulus) for a camphor like aroma. Also, citrus oils such as Lemon (Citrus limon) or Grapefruit (Citrus paradisi) for a fresh sharp aroma. Or try Lavender (Lavendula angustifolia) or Geranium (Pelargonium graveolens) for a floral aroma. Do not use in pregnancy, keep away from eyes, do not use on children.
