Aromatherapy is a type of alternative medicine that uses essential oils and other aromatic plant compounds which are aimed at improving a person's health or mood.
Aromatherapy is a widely used term for a range of traditional therapies that use essential oils. These may include massaging oils, or any topical application that uses pure, essential oils - the essential oils are either absorbed through the skin or inhaled.
It is believed that the inhalation of essential oils stimulates the part of the brain connected to smell - the olfactory system; a signal is sent to the limbic system of the brain that controls emotions and retrieves learned memories. This causes chemicals to be released which make the person feel relaxed, calm, or even stimulated. If the aromatherapy includes massage the effect is to further relax the person.
