This is a therapeutic type of healing used to alter mood and health and well being through scent, smell and aroma. Plant extracts are distilled creating oils with aromas that penetrate the olfactory or limbic systems. Aromatherapy can reduce anxiety, enhance energy, increase short term memory and provide relaxation. For example sage can boost short term memory, lavender is used for anti stress and relaxation, and lemon oil is a good anti depressant. Aromatherapy is often used during massage, energy healing and spa treatments.
