The grapefruit tree was originally from Asia but it is now grown and harvested in the United States, France, Brazil and Israel. The grapefruit tree itself is a large tree about 10 meters (30 feet) tall, with glossy leaves, white flowers and large, pale yellow fruits with pink flesh. The differences between the White and Pink Grapefruits are minor, but more Pink Grapefruit is produced because it is sweeter. The difference in cost is simply from supply and demand.Cautions: This Essential Oil has phototoxic properties and exposure to the sun must be avoided after application to the skin.
