From My Spa Treatment:
Massage is perhaps the most popular way to use essential oils. It combines the healing art of aromatherapy with the healing art of touch.
Self-massage is just as effective as being massaged by another person, and lack of a partner is no excuse for not trying these relaxing recipes. Always use essential oils diluted in a carrier oil. Never place them directly onto the skin. As a general rule, do not exceed ten drops of total essential oils per mixture, and try to keep it around five for maximum effectiveness. Aromatherapy massage is particularly suited to conditions involving stress or improving emotionally-related conditions.
