Aromatherapy is the therapeutic use of essential oils to promote health and well-being. Essential oils are compounds derived and extracted from plants such as flowers, leaves, bark, roots, fruits, seeds, grasses, and resins. They have versatility in their means of use, including inhalation (through the use of a diffuser), topically through the skin (through massages, ointments, and compresses), and water immersion (through bath). Aromatherapy can be used alongside traditional therapy to treat certain health conditions, such as reducing anxiety and stress and promoting sleep and relaxation.
