Aromatherapy is the inhalation of plant oils, called essential oils, for improved physical, mental, and emotional well-being. Essential oils are the pure essence of the plant—often referred to as nature's living energy—and can provide both psychological and physical benefits when used correctly. Essential oils can be used on their own for aromatherapy or with complementary natural ingredients, such as vegetable or carrier oils.
There are two ways to use essential oils for aromatherapy: inhalation and topical application.
