The grapefruit was first described in the 1750s as the "forbidden fruit" of Barbados. It was introduced to Florida in the 1820s. Most grapefruit in the United States is still grown in Florida. Grapefruit juice has been used in folk medicine for the treatment of diabetes as well as to strengthen the immune system. Grapefruit is also added to cosmetics and hair care products as a fragrance.
Grapefruit has been suggested as a treatment for several conditions, but there is currently insufficient scientific evidence to support the use of grapefruit for any medical disorder. The use of supplemental grapefruit pectin in the prevention of cardiovascular disease and the use of grapefruit seed extract in atopic eczema warrants further scientific investigation before a strong recommendation can be made. There is conflicting research regarding the use of grapefruit for kidney stones.
Grapefruit juice alters the way some drugs are broken down in the liver. Grapefruit may increase the effects of calcium channel blockers, benzodiazepines, immunosuppressants, and HMG-CoA reductase inhibitors.

Endocrine disorders (metabolic syndrome):
Early studies suggest grapefruit may have some benefit in the management of metabolic syndrome. More studies are needed to understand this relationship.
Grapefruit pectin supplementation may inhibit high cholesterol. There is promising but inconclusive human evidence to support the use of grapefruit pectin in the prevention of heart disease. Additional study is needed in this area.
There is limited and mixed research regarding the use of grapefruit for kidney stones. Further research is needed to clarify these results.
