Prunus armeniaca L.
Common Name Apricot
Family Rosaceae
Synonyms Armeniaca vulgaris.
Known Hazards
This species produceshydrogen cyanide, a poison thatgives almonds their characteristicflavour. This toxin is found mainlyin the leaves and seed and isreadily detected by its bitter taste.Usually present in too small aquantity to do any harm, any verybitter seed or fruit should not beeaten[65]. In small quantities,hydrogen cyanide has beenshown to stimulate respirationand improve digestion, it is alsoclaimed to be of benefit in thetreatment of cancer. In excess,however, it can cause respiratoryfailure and even death. Oraldoses of 50g of hydrogencyanide can be fatal (= 30g ofkernels or 5060 kernels at 2 mgHCN/g kernel) [301].

Fruit raw, cooked or dried for later use[1, 2, 3, 34]. The best forms are soft and juicy with a delicious rich flavour[K]. Wild trees in the Himalayas yield about 47.5kg offruit per year[194].The fruit of the wild form contains about 6.3% sugars, 0.7% protein, 2.5% ash, 2.5% pectin. There is about 10mg vitamin C per 100g of pulp[194].The fruit is about 5cm in diameter and contains one large seed[200]. Seed raw or cooked[183]. Bitter seeds should be eaten in strict moderation, but sweet ones canbe eaten freely[132]. The bitter seeds can be used as a substitute for bitter almonds in making marzipan etc[4]. An edible gum is obtained from the trunk[64]. The seedcontains up to 50% of an edible semidrying oil[4, 57, 61, 183].
Medicinal Uses
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plantmedicinally.
Analgesic; Anthelmintic; Antiasthmatic; Antidote; Antipyretic; Antiseptic; Antispasmodic; Antitussive; Demulcent; Emetic; Emollient; Expectorant; Laxative; Ophthalmic; Pectoral; Sedative; Tonic; Vulnerary.
Apricot fruits contain citric and tartaric acid, carotenoids and flavonoids[283]. They are nutritious, cleansing and mildly laxative[254. They are a valuable addition to thediet working gently to improve overall health. The salted fruit is antiinflammatory and antiseptic[283]. It is used medicinally in Vietnam in the treatment of respiratoryand digestive diseases[283]. Antipyretic, antiseptic, emetic, ophthalmic[194]. The flowers are tonic, promoting fecundity in women[218]. The bark is astringent[254]. Theinner bark and/or the root are used for treating poisoning caused by eating bitter almond and apricot seeds (which contain hydrogen cyanide)[218]. Another reportsays that a decoction of the outer bark is used to neutralize the effects of hydrogen cyanide[238]. The decoction is also used to soothe inflamed and irritated skinconditions[254]. The seed is analgesic, anthelmintic, antiasthmatic, antispasmodic, antitussive, demulcent, emollient, expectorant, pectoral, sedative andvulnerary[176, 218]. It is used in the treatment of asthma, coughs, acute or chronic bronchitis and constipation[176, 279]. The seed contains 'laetrile', a substance thathas also been called vitamin B17[218]. This has been claimed to have a positive effect in the treatment of cancer, but there does not at present seem to be muchevidence to support this[K]. The pure substance is almost harmless, but on hydrolysis it yields hydrocyanic acid, a very rapidly acting poison it should thus be treatedwith caution[218]. In small amounts this exceedingly poisonous compound stimulates respiration, improves digestion and gives a sense of wellbeing[238].
Other UsesAdhesive; Dye; Gum; Oil; Oil; Wood.
An edible semidrying oil is obtained from the seed[57]. Used for lighting[194]. The oil has a softening effect on the skin and so it is used in perfumery and cosmetics,and also in pharmaceuticals[4, 61]. A green dye can be obtained from the leaves[168]. A dark grey to green dye can be obtained from the fruit[168]. Wood handsome,hard, durable. Agricultural implements etc[146, 194].
