Although poisonous, saponins also have a range of medicinal applications and many saponin-rich plants are used in herbalism (particularly as emetics, expectorants and febrifuges) or as sources of raw materials for the pharmaceutical industry. Saponins are also found in a number of common foods, such as many beans. Saponins have a quite bitter flavour and are in general poorly absorbed by the human body, so most pass through without harm. They can be removed by carefully leaching in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of raw foods that contain saponins. Saponins are much more toxic to many cold-blooded creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish and make them easy to catch[ K Title Plants for a Future Author Ken Fern Description Notes from observations, tasting etc at Plants For A Future and on field trips. ]. Alfalfa sprouts (and especially the seeds) contain canavanine.

Botanical Description
Medicago sativa is a herbaceous perennial plant with erect to ascending, rarely prostrate, much-branched stems growing from a deep taproot; it can grow from 30 - 100cm tall[ 277 Title Plants Database Publication Author Website http://plants.usda.gov/java/factSheet Publisher United States Department of Agriculture Year 0 ISBN Description An online database with an excellent collection of fact sheets about native N. American plants. ]. The plant is harvested from the wild for use as a food and medicine. Alfalfa has long been cultivated for its wide range of uses, including its edible seed, which can be sprouted and eaten in salads. It is also commonly grown as a green manure and soil restorer. The wild subspecies of Medicago sativa are widespread across Eurasia, with no major threats and stable populations. They are also well conserved in ex situ gene bank collections. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[ 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. ].
