These oils are blends carefully selected, each for a specific purpose. Aromatherapy works on two levels: 1) essential oils penetrate the skin or are inhaled and then interact chemically with the body and 2) the scents act on the brain, stimulating memories and/or emotional responses. Sugarhill Oils may be massaged directly into the skin, used as a perfume, or several drops may be placed in a diffuser such as a light bulb ring, candle diffuser, or even a small pot of boiling water.
