Korean cherry ("Prunus japonica" or "Cerasus japonica"), also called flowering almond or oriental bush cherry, is a shrub species in the genus Prunus. It is mainly cultivated for ornamental use.

Description

The shrub reaches 1.5 m by 1.5 m. Its flowers are hermaphrodite and are pollinated by insects. The plant blossoms in May. Its fruit reaches about 14 mm and has an agreeably sweet flavor, therefore it is used in making pies, but its taste is quite sour, reminiscent of that of cherry.

Every fruit has one seed. The plant usually grows from seed but can also be multiplied by cutting for layering.

Habitat

The plant thrives best on well-drained and moist loamy soil and prefers little shade or no shade at all. The plant prefers some lime in the soil but not too much. It is mostly found at woodlands or sunny places.

Medical interest

Although this is not yet scientifically established, the species is thought to contain amygdalin and prunasin, as is the case at all the other members of the genus "Prunus". These chemical compounds break down in water to form hydrocyanic acid, an extremely poisonous substance that when taken in very small amount can stimulate respiration and improve digestion.

The kernel of "Prunus japonica" is highly versatile: it is deobstruent, aperient, demulcent, carminative, diuretic, laxative, hypotensive, ophthalmic and lenitive. It can also be prescribed for internal use in treating dry constipation, oedema or post-traumatic insomnia. Other part of the plant is also used, but more rarely. For instance, the root acts against constipation, child fever, pinworms and teeth problems.

Other uses

The leaves of this plant procure a green dye, while the fruit procures a greenish to grayish dye.
