Essential oils stimulate the nerves and the olfactory system. Aromatherapists believe that the oils are picked up by the nerve endings and passed on until they eventually reach the pituitary gland. This, in turn, affects the adrenals, thereby reducing stress. Certain oils are known to be calming and relaxing, while others are said to lift one's spirit. Essential oils can be compounded into massage creams, lotions, vaporizers, bath oils.
