| Origin: | |
| Peach kernel is the ripe seed of the fruit tree Prunus persica (L.) Batsch, or Prunus davidiana (Carr.), of the Rose family (Rosaceae), grown throughout the warmer temperate regions of both the Northern and Southern hemispheres. The peach probably originated in China, then spread westward through Asia to the Mediterranean countries and later to other parts of Europe. The Spanish explorers brought the peach to the New World, and as early as 1600 the fruit was found in Mexico. Small to medium-sized, the tree seldom reaches 6.5 m in height. Under cultivation, however, it is usually kept between 3 and 4 m by pruning. Leaves are glossy green, lance-shaped, and long pointed; they usually have glands at their bases that secrete a fluid to attract ants and other insects. The flowers, borne in the leaf axils, are arranged singly or in groups of two or three at nodes along the shoots of the previous season's growth. Worldwide, the peach is the third most important of the deciduous-tree fruits, ranking after the apple and the pear. The United States, where the peach ranks second to the apple, produces about a fifth of the world's supply. Italy is second, with about one-sixth the world supply. France, China, Spain, Greece, Argentina, Japan, Turkey, Mexico, South Africa, and Australia also produce substantial crops. In China, peach is distributed in most areas and mainly produced in central and south China. Reaped when the fruit ripens, the Kernels are collected, removed of the seeds, skinned and dried in the sun for use when raw or after being parched. |

| Cautions on Use: | |
| The seed can contain high levels of hydrogen cyanide, a poison that gives almonds their characteristic flavor. This toxin is readily detected by its bitter taste. Usually present in too small a quantity to do any harm, any very bitter seed or fruit, however, should not be eaten. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause headache, blurred vision, palpitations or even death from respiratory failure. Peach kernel should be avoided by pregnant women and used carefully by anyone with loose stools. |
