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. Laetrile™, an alternative cancer drug marketed in Mexico and other countries outside of the United States, is derived from amygdalin. Laetrile™ 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 Laetrile™ 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).
There is currently a lack of available scientific evidence to recommend any medicinal dosing for apricot in adults. Apricot kernels (approximately 7-10) taken by mouth may be a lethal dose.
There is currently a lack of available scientific evidence to recommend any medicinal dosing for apricot in children.
Apricot fruit is likely safe when ingested in food amounts. Apricot kernel oil has Generally Recognized as Safe (GRAS) status in the United States. Apricot fruits are possibly unsafe when taken by mouth by diabetics, as apricot contains sugars and may affect blood sugar levels. Apricot kernels may also lower blood pressure. Urticaria ("hives") and rash have also been reported.
Apricot pits are not well tolerated and are toxic at low to moderate dosing levels. Multiple cases of cyanide poisonings, some of which were fatal, have been associated with the use of Laetrile™ and apricot pits. Cyanide poisoning symptoms may include vomiting, diarrhea, abdominal pain, lethargy, rapid or irregular breathing, and skin discoloration. Coma, shock, metabolic acidosis (acidic pH in the blood), dizziness, severe headache, dilated pupils, blindness, drowsiness, decreases in white blood counts, hypothermia (lowering of the core body temperature), mental retardation, paralysis, goiter, thyroid cancer, cretinism (stunted physical and mental growth in infants and children due to a lack of thyroid hormone) have also been reported. Furthermore, generalized convulsions/seizures, ataxia (loss of coordination), muscle weakness, muscle spasms or muscle tension have been noted in the scientific literature.
Apricot kernels may cause decreases in blood pressure, and therefore may interact with blood pressure lowering medications. A qualified healthcare professional, including a pharmacist, should be consulted.
Apricot kernels may cause decreases in blood pressure, and therefore may interact with blood pressure lowering herbs and supplements. A qualified healthcare professional, including a pharmacist, should be consulted.
Laetrile™ and apricot kernels both contain amygdalin, and concomitant use may result in cyanide poisoning. Caution is advised.
