This massage activates the molecules of essential oils, already blended with a carrier oil, which penetrates the blood stream and soothes the central nervous system. The medicinal properties of essential oils act on the internal organs and treat ailments. Although the oil only remains in the body for three to four hours before they are excreted from the body, they have already triggered a healing process. The massage therapist can select oils that are relaxing, energizing, stress-reducing, balancing, etc. One of the most common essential oils used in aromatherapy massage is lavender. Aromatherapy massage is particularly suited to stress-related conditions or conditions with an emotional component.
