Grapefruit oil is great for working with adolescent melancholia and acne. It is cold-pressed from the rind of the grapefruit. I can be applied topically to troubled areas of the skin as a cleanser. This allows the person to take it in through the skin as well as the lungs. It disinfects, detoxifies, emotionally uplifts and can have an antidepressant effect. It is a great match for an adolescent with a troubled attitude. It is often used for cellulite on the skin as well.
