Inhaling the aroma of grapefruit essential oil (or absorbing grapefruit essential oil through the skin) is thought to transmit messages to a region of the brain involved in controlling emotions. Known as the limbic system, this region of the brain also influences the nervous system. Aromatherapy proponents suggest that essential oils can affect a number of biological factors, including heart rate, stress levels, blood pressure, respiration, and immune function. Grapefruit essential oil is also used to reduce stress, stimulate circulation, increase energy, improve mood and digestion.
