Grapefruit🍊

A small evergreen tree in the rue family, a hybrid that arose in 18th-century Barbados from natural crossing of pomelo (C. maxima) and sweet orange (C. sinensis). The name 'grapefruit' comes from the grape-like clusters of fruit. Florida and Texas (USA), Israel, and South Africa are major production areas; Japan relies mostly on imports. The flesh is white, pink, or red, with characteristic bitterness from naringin. Known to interact with many medications (via CYP3A4 inhibition) — caution is needed during drug therapy.
