In aromatherapy, inhaling the aroma of Grapefruit Essential Oil (or absorbing grapefruit essential oil through the skin) is thought to transmit messages to a brain region involved in controlling emotions. Known as the limbic system, this brain region also influences the nervous system. Aromatherapy proponents suggest that essential oils may affect a number of biological factors, including:
- Heart rate
- Stress levels
- Blood pressure
- Immune function
Grapefruit is well-known for its ability to support a healthy metabolism. Another recent study showed that the scent of grapefruit essential oil increased activity in the gastric vagal nerve in rodents, resulting in lower appetite. This nerve plays an important role in stimulating the production of stomach juices needed for digestion. Support your metabolism at home or on-thego by adding one to two drops of Grapefruit oil to your water. This essential oil addition to your drinks will also give your water a flavor-filled and vitalizing boost.
