Aromatherapy is the practice of using scent to stimulate a healing response for curing physical, emotional, and mental health issues. Essential oils, formed from the aromatic compounds found in flowers, seeds, stems, roots, leaves, and fruits, can be used in the bath, in skin care products, and in diffusers for application in the air. Aromatherapy covers how to use essential oils safely and effectively and provides recipes for combinations of scents for specific health needs.
