Massage therapy is a very natural form of health care that does not require the ingestion of any medications, drugs, or surgical procedures. Aromatherapy massage therapists aren't allowed to provide a individual's medication to help them with their illness if it's contrary to the express wishes of the individual. Aromatherapy massage therapists are also permitted to use essential oils to help their patients. The use of essential oils throughout massage therapy has been practiced for thousands of years. The key essential oils used are rose, lavender, lemon, peppermint, jasmine, and rose. These essential oils are all natural, safe substances that have no ill side effects.
