How long do essential oils last in the body?
Essential oils will last 12 – 24 hours in the body depending on several factors: viscosity, concentration, application method (massage or diffuser), skin type and to which body part the oils were applied. After entering the blood stream, essential oils are circulated to the tissues and organs. They will eventually pass into the lymphatic system and will then be eliminated through sweat and normal bodily functions. Combined with massage, the effect of essential oils can last for days. Also, due to the link with the emotional centers of the brain, the effect of a subtle scent can leave an impression for a lifetime. .
