Safety & Hazards
Although no specific information has been seen, the seed and other parts of the plant (but not the fruit) are likely to contain cyanogenic glycosides. 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. Publication Author Bown. D. Publisher Dorling Kindersley, London. Year 1995 ISBN 0-7513-020-31 Description A very well presented and informative book on herbs from around the globe. Plenty in it for both the casual reader and the serious student. Just one main quibble is the silly way of having two separate entries for each plant. ]. It is also claimed by some to be of benefit in the treatment of cancer - though this claim has been largely refuted. In larger concentrations, however, cyanide can cause gasping, weakness, excitement, pupil dilation, spasms, convulsions, coma and respiratory failure leading to death[ 293 Title Poisonous Plants of North Carolina Publication Author Website http://www.ces.ncsu.edu/depts/hort/consumer/poison/poison.htm Publisher Year 0 ISBN Description An excellent concise but comprehensive guide to toxic plants that grow in N. Carolina. It lists even those plants that are of very low toxicity, including several well-known food plants such as carrots and potatoes. ]. The levels of toxin can be detected by the level of bitterness:- sweet almonds, for example, contain only very low levels of it and are safe to eat in quantity, whilst bitter almonds (which are used as a flavouring in foods such as marzipan) contain much higher levels and should only be eaten in very small quantities. Great caution should be employed if the taste 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. ].

It is still widely cultivated in central and northern Yunnan in China, being popular because of its early season of ripening, and is sold in local markets in Korea[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. , 1665 Title Wild Food Plants in South Korea; Market Presence, New Crops, and Exports to the United States Publication Economic Botany, Vol. 50, No. 1 (Jan. - Mar., 1996), pp. 57-70 Author Pemberton R.W. & Nam Sook Lee Website http://www.jstor.org/stable/4255805 Publisher Year 1996 ISBN Description ].
