Did you know that the grapefruit is thought to be a hybrid between pomelo (citrus maximus) and the sweet orange (Citrus sinensis)? Captain Shaddock cultivated the pomelo and sweet orange seeds in Jamaica (18th century) which soon led to its hybridization! Grapefruit oil may help with cancer, eating disorders, fatigue, jet lag, liver disorders, migraine headaches, and premenstrual tension. Its fragrance is mood elevating and has been used to help with depression. It may also have the ability to cleanse the kidneys, the lymphatic system, and the vascular system.
