'''''Senna''''' is a large genus of about 250–260 species of [[flowering plant]]s in the family [[Fabaceae]], subfamily [[Caesalpinioideae]]. This [[biodiversity|diverse]] genus is native throughout the [[tropics]], with a small number of species reaching into [[temperate|temperate region]]s.

Typically ''Senna'' species have yellow flowers. Some species of ''Senna'' are notable for being host to particular butterfly species — for instance [[Cloudless Sulphur]] butterflies.

''Senna alexandrina'' is a small [[shrub]], about 0.5-1 m high, with a pale green smooth erect [[Plant stem|stem]], long spreading [[branch]]es, bearing four or five pairs of [[leaves]]. The [[flower]]s are small and yellow, the [[pod]]s broadly oblong and containing about six [[seed]]s.

Senna is an [[Arab]]ian name, and the plant is grown mostly in [[Nubia]]. Twice a year the plants are cut down, dried in the sun, stripped and packed in [[Arecaceae|palm]]-leaf bags and sent on [[camel]]s to [[Essouan]] and [[Darao]] then up the [[Nile]] to [[Cairo]] or else to [[Red Sea]] ports.

It is a [[purgative]], similar to [[aloe]] and [[rhubarb]] in having as active ingredients [[anthraquinone]] derivatives and their [[glucoside]]s. Its action is on the lower [[bowel]], and is especially useful in alleviating [[constipation]]. It increases the [[peristalsis|peristaltic]] movements of the colon.

Another species of senna, ''[[Cassia obovata]]'', is used as a [[hair]] treatment with effects similar to [[henna]], but without the red color. The active component is an anthraquinone derivative called ''chrysophanic acid'', which is also found in higher concentrations in rhubarb root. It adds a slight yellow color. ''Cassia obovata'' is often called "neutral henna".

==Uses==
===Medicinal Use===

Because of the presence of [[anthraquinone]]s, senna species are used as the primary ingredient in certain commercial [[stimulant]] [[laxative]]s. It is also the primary ingredient found in most "dieter's tea." The combination of acting as a [[stimulant]] which reduces a dieter's appetite, and the [[laxative]] properties that cause food to move through their system before as many calories can be absorbed is a combination that can lead to rapid and even dangerous weight loss.

The [[stimulant]] action of [[Sennosides]], the active ingredient in teas and tablets, should be taken into account for those who suffer from any conditions where [[stimulant | stimulants]] are [[contraindicated]], such as past [[heart disease]], [[high blood pressure]], [[Anxiety_attack|anxiety attacks]], etc.

===Culinary use===
In some [[Southeast Asia]]n cuisines (particularly those of [[Thai cuisine|Thailand]] and [[Lao cuisine|Laos]]), the leaves and flowers of Siamese Cassia (''[[Senna siamea]]'', called ''khi-lek'' in [[Thai language|Thai]]), either fresh or pickled in brine, are used in cooking, particularly in ''gaeng khi-lek'' (''khi-lek'' curry).[http://www.thai4uk.com/acatalog/shop.html?http%3A//www.thai4uk.com/acatalog/Vegetables_Herbs.html&CatalogBody][http://eatingasia.typepad.com/eatingasia/2005/09/gaeng_ki_lek_on.html]
