Grapefruit is an oil that helps you feel good inside and out. I think everyone should drink grapefruit oil as often as they can, even daily. dōTERRA grapefruit oil smells sharp and clean just like fresh grapefruit should. The essential oil is from the rinds (peel)--not the fleshy fruit. The rind has a completely different chemical makeup, so those people who have been 'advised' not to eat grapefruit or oranges can now rest assured in using the essential oil without incident. Grapefruit is an ingredient in the following blends: dōTERRA Slim & Sassy Metabolic Blend, AromaTouch massage Blend, and Citrus Bliss Invigorating Blend.
