White sapote (Casimiroa edulis), also known as Cochitzapoti in Nahuatl (meaning 'sweet-tasting fruit which causes sleepiness) is a species of tropical fruiting tree in the family Rutaceae, native to eastern Mexico and Central America south to Costa Rica. Mature trees range from 5-16 m tall and are evergreen. The leaves are alternate, palmately compound with 3-5 leaflets, the leaflets 6-13 cm long and 2.5-5 cm broad with an entire margin, and the leaf petiole 10-15 cm long. The fruit is an ovoid drupe, 5-10 cm in diameter, with a thin, inedible skin turning from green to yellow when ripe, and an edible, somewhat peach-flavoured creamy-white pulp. It contains a single seed that is said to have narcotic properties. Along with their seeds, the leaves of the trees are known to have a sedative effect and are very good agents for lowering arterial blood pressure.
In the past 40 years, extensive experiments have been carried out on the White Zapote's seeds which have yielded the identity of many pharmacologically active compounds, including: n-methylhistamine, n-dimethylhistamine, histidine and histamine.
Unlike the mamey sapote, white sapote is a member of the family Rutaceae, to which citrus belongs. The black sapote is also unrelated and is actually a species of persimmon. This confusion may be due to the fact that "sapote" comes from the Aztec word "tzapotl", used to describe all soft, sweet fruit.
