Physical Characteristics

Prunus sibirica is a deciduous Shrub growing to 3 m (9ft 10in). See above for USDA hardiness. It is hardy to UK zone 5. It is in flower in March, and the seeds ripen from July to August. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Distribution

E. Asia - China, Korea, Mongolia and eastern Siberia.

Edible Uses

Edible Parts: Fruit Oil Seed Edible Uses: Condiment Oil Fruit - raw or cooked[2, 105]. A good size, it is about 25mm x 25mm and contains one large seed[200]. Sour and scarcely edible[11, 266]. The fruit is occasionally eaten. Seed - raw or cooked. A bitter taste[11], they are normally used as an almond flavouring[74, 105]. Do not eat the seed if it is too bitter - see the notes above on toxicity. An edible oil is obtained from the seed[183] - it is used as an almond flavouring[74]. The oil resembles olive oil[183].

Medicinal Uses

Analgesic Antiasthmatic Antiseptic Antitussive Digestive Emollient Laxative Tonic The seed is analgesic, antiasthmatic, antiseptic, antitussive and emollient[176]. It is used in the treatment of coughs, asthma, acute or chronic bronchitis and constipation[176]. The seed contains amygdalin and prunasin, substances which break down in water to form hydrocyanic acid (cyanide or prussic acid). In small amounts this exceedingly poisonous compound stimulates respiration, improves digestion and gives a sense of well-being[238].

Known Hazards

Although no specific mention has been seen for this species, it belongs to a genus where most, if not all members of the genus produce hydrogen cyanide, a poison that gives almonds their characteristic flavour. This toxin is found mainly in the leaves and seed and is readily detected by its bitter taste. It is usually present in too small a quantity to do any harm but any very bitter seed or fruit 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 respiratory failure and even death.
