Research the type of oil that effectively treats your particular injury, and add 5-7 drops of oil into the bowl. Fold a washcloth and submerse in the water. Gently remove excess water and apply washcloth to affected area. Continue for 5 minutes. This should almost never be done.
Many oils are too strong to be directly inhaled.
Inhalation should be done with diluted oils. The process is much like a facial. Fill a bowl with steaming water, and add 5-7 drops of the desired oil. Placing a towel over the head, lean over the bowl and inhale deeply several times. Remove towel and inhale several breaths of fresh air.
