Aromatherapy means "treatment using scents". It is a holistic treatment of caring for the body with pleasant smelling botanical oils such as rose, lemon, lavender and peppermint. The essential oils are added to the bath or massaged into the skin, inhaled directly or diffused to scent an entire room. Aromatherapy is used for the relief of pain, care for the skin, alleviate tension and fatigue and invigorate the entire body. Essential oils can affect the mood, alleviate fatigue, reduce anxiety and promote relaxation. When inhaled, they work on the brain and nervous system through stimulation of the olfactory nerves.
