How do you use essential oils? Diffuser Essential oils are placed in diffuser, sometimes with water, and sometimes with heat so they evaporate. This is a good way to add the scent of an essential oil to a room. Dry evaporation Several drops of essential oil are placed on a cotton ball or tissue and allowed to evaporate into the air. If a milder, more constant exposure is desired, simply keep the cotton ball in your immediate vicinity. Steam Drops of essential oil are added to a bowl of steaming water, which quickly vaporizes the oil, breathe deeply. Spray Drops of essential oils are placed in a water-based solution, shaken, and sprayed into the air in order to deodorize a room or set a mood. Bath Drops of essential oils are added to bath water in a dispersant immediately before stepping in. This method results in absorption through the skin, as well as inhalation of the volatilized essential oil. Massage Drops of essential oil are added to a natural carrier oil and applied to skin areas with gentle rubbing. Massage blends should not exceed 1 concentration of essential oils (one drop in a teaspoon) for adults. SAFETY WARNING For external use only.
