- Apricot generally refers to the fruit of the Prunus armeniaca tree. The tree is moderately sized with reddish bark. The fleshy fruit encloses a hard nut surrounding a droplet-shaped, reddish-brown seed or pit. Cultivation of apricot in China dates back 3,000 years and spread to Armenia, and then to Europe. The Romans introduced apricots to Europe around 70-60 B.C. through Greece and Italy.
- The most commonly used part of the apricot in alternative medicine may be the pit, which is also known as the kernel or seed. Apricot pit contains amygdalin, a plant compound that contains sugar and produces cyanide. Laetrileâ„¢, an alternative cancer drug marketed in Mexico and other countries outside of the United States, is derived from amygdalin. Laetrileâ„¢ remains unapproved by the U.S. Food and Drug Administration (FDA) and does not appear to be effective for treating cancer. Apricot pits and/or Laetrileâ„¢ may cause cyanide poisoning.
- Apricot kernels and oils have been historically used to treat tumors. The Japanese folk remedy bainiku-ekisu (concentrated Japanese apricot juice) has been used for the treatment of gastritis (stomach inflammation) and enteritis (bowel inflammation) since ancient times, and has recently been studied as a bacteriostatic (stops the growth/reproduction of bacteria) agent. Amygdalin may also be useful for AIDS patients, psoriasis, and hyperoxia (excess of oxygen).
