All ancient cultures have used plants as medicine and many moderns drugs started life as plant extracts. Aromatherapy combines the therapeutic properties of plants with massage. 
After a consultation, I blend oils specifically for the client and the body absorbs the oils through the skin during the massage. I would probably blend something totally different for say a muscle injury than a stress problem, and may vary the massage techniques.
Wherever possible I use organic essential oils and cold pressed base oils for all products and treatments.
