Edible Uses

Edible Parts: Fruit Seed Edible Uses: Fruit - raw or cooked[105, 161, 177]. Considered to be a great delicacy[257]. Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.

Medicinal Uses

Antirheumatic Astringent Pectoral A decoction of the stems, leaves or roots has been used in the treatment of diarrhoea[257]. A weak decoction of the bark has been used in the treatment of rheumatism[257]. A hot infusion of the branches or the leaves has been used in the treatment of colds[257]. A decoction of the dried bark strips has been used as a winter tonic to ward off influenza[257]. All members of the genus contain 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.
