You can treat nausea and vomiting quickly and effectively by putting 1-2 drops of Sweet Basil on a tissue for inhalation. Peppermint is another great option!
Inhaling essential oils gives the oil contact with your nasal passages, sinuses, and lungs. Essential oils are able to cross into your bloodstream quickly because your respiratory system is lined with a very thin mucous membrane, which has a wealth of capillaries waiting to snatch up and deliver chemical constituents as they pass through.
You can also consider adding a few drops of peppermint or sweet basil essential oil to a bowl of steaming water. Simply place your face close to the bowl, cover your head with a towel and inhale. Other options include using a humidifier, a diffuser, or an immune-boosting spray.
For young children, diffusion is an excellent option because only small amounts of the essential oils reach the body. To treat an illness diffuse 4-5 times per day for approximately seven minutes at a time. After seven minutes the central nervous system adapts to the smell and you can discontinue until your next session.
