Safety & Hazards
Consumption of the seeds can lead to liver cancer[ 398 Title Edible Wild Plants of Tanzania Publication Author Ruffo, C.K.: Birnie, A. & Tengnas, B. Publisher Regional Land Management Unit; Nairobi. Year 2002 ISBN 9966-896-60-0 Description A very well presented, simple guide to growing and utilizing wild food plants in Tanzania, with line drawings of each plant, a description, habitat and range, non-food as well as food uses, plus basic information on growing the plants. ]. We have no further 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.

The plant can reach up to 6 metres tall, though it is often much shorter. The dark green, arching, pinnate, leaves can be 3 metres long, the leaf stalk bearing about 80 pairs of stiff, tough and leathery leaflets, 15 - 35 cm long[ 398 Title Edible Wild Plants of Tanzania Publication Author Ruffo, C.K.: Birnie, A. & Tengnas, B.

The plant is harvested from the wild for use as an emergency food in times of shortage. It is often grown as an ornamental. Habitat destruction as a result of urban expansion, coastal resort development, and agricultural expansion is having a direct impact on this species. Former large subpopulations of the species have been lost as result. The plant is classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2011)[ 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. ].
