Safety & Hazards
The bark, bruised leaves and fruits smell strongly of bitter almonds, suggesting the presence of hydrogen cyanide. They are reputed to be poisonous and are used in witchcraft[ 418 Title Ecocrop Publication Author Website http://ecocrop.fao.org/ecocrop/srv/en/home Publisher Year 0 ISBN Description Basic information on a wide range of useful plants, plus details of environmental needs where available. ]. The plant (especially the seed and young shoots) contains cyanogenic glycosides, especially amygdalin and prunasin. When injested, these compounds break down in the digestive tract to release cyanide. Used in small quantities in both traditional and conventional medicine, this exceedingly poisonous compound has been shown to stimulate respiration, improve digestion, and promote a sense of well-being[ 238 Title Encyclopaedia of Herbs and their Uses.

It is also claimed by some to be of benefit in the treatment of cancer - though this claim has been largely refuted.

Carolina. It lists even those plants that are of very low toxicity, including several well-known food plants such as carrots and potatoes. ]. The fruits and flowers of most members of this genus generally have low or very low concentrations of this toxin, though the seeds and young shoots can contain much higher levels. The levels of toxin can be detected by the level of bitterness:- for example sweet tasting almond seeds are a major food crop and are often eaten in quantity, whilst bitter tasting almond seeds are used as a flavouring (in marzipan for example) but are not usually eaten on their own. In general, it can be considered safe to eat any fruit or seed from species in this genus that either have a sweet flavour or are slightly bitter. Great caution should be taken, however, if the flavour is moderately to very bitter[ K Title Plants for a Future Author Ken Fern Description Notes from observations, tasting etc at Plants For A Future and on field trips. ].
