"The origin of Grapefruit is a mystery. Most likely the grapefruit is a genetic blend of the pumelo fruit and the sweet orange; giving it a wonderfully sharp, citrus aroma unlike any other. Grapefruit essential oil is extracted from tiny pockets of oil in the skin of the fruit. The peel is pressed, releasing a burst of sharp citrus oil with an underlying sweetness. This detoxifying oil is often used in cleansing and clarifying aromatherapy treatments. When used in massage, Grapefruit can help stimulate kidney function and rid the body of excess fluid. Used in a diffuser or aromatherapy roll on, Grapefruit can sharpen concentration, improve mental clarity and help to boost self-confidence. "
