The use of essential oils (extracted from herbs, flowers, resin, woods, and roots) in body and skin care treatments is known as aromatherapy. Used as a healing technique for thousands of years by the Egyptians, Greeks, and Romans, essential oils aid in relaxation, improve circulation, and help the healing of wounds. Aromatherapy diffusers are utilized to fill the massage room with the scent of the oils. Specific essential oils are blended by the aromatherapist and added to a carrier oil, such as almond oil, to be used during the massage. Each oil has its own unique characteristics and benefits.
