Encephalartos sclavoi
Safety & Hazards
We have no specific information for this species, but most if not all members of this genus are believed to contain toxins. The two main toxic compounds that have been identified are cycasin and macrozamin. When ingested in sufficient quantities, these compounds are extremely poisonous to humans and many other animals, and have been shown to cause liver damage and cancer. Cycasin and macrozamin have a cumulative effect upon the body and are suspected of causing neurological disorders when ingested in small amounts over long periods of time. There is a long history of human use of this genus as a starch-rich food, but it should be noted that the plants needed to be treated in various ways in order to remove any toxic principles. Caution should be exercised even with properly prepared foods, since even then regular consumption may lead to severe health problems and death. Since many of these species are becoming increasingly rare in the wild, this is probably a food best left to times of food shortage when other, better foods, are not available[ 1935 Title The Cycads Publication Author Whitelock L.M.

Encephalartos sclavoi has a very small area of occupancy, is known from a single location where the population size is less than 50 mature individuals, and there is continuing decline due to loss in the extent and quality of habitat and decline in the population due to collection by traditional healers and by cycad collectors. The plant is classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2010)[ 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. ].
