Senna alexandrina (Alexandrian Senna, and see below) is an ornamental plant in the genus Senna. It is also used in herbalism. It grows natively in upper Egypt, especially in the Nubian region, and near Khartoum (Sudan), where it is cultivated commercially. It is also grown elsewhere, notably in India and Somalia.

Alexandrian Senna is a shrubby plant that reaches 0.5-1, rarely two meters in height with branched pale green erect stem, long spreading branches, bearing four or five pairs of leaves. These are complex feathery mutual pairs. The leaflets are varying from 4 to 6 pairs, fully edged, with a sharp top. The midribs are equally divided at the base of the leaflets. The flowers are in a raceme interior blossoms, big in size, coloured yellow that tends to brown. Its legume fruit are horned, broadly oblong, compressed and flat and contain about six seeds.

When cultured, twice a year the plants are cut down, dried in the sun, stripped and packed in palm-leaf bags. They are then sent on camels to Essouan and Darao, then up the Nile to Cairo or else to Red Sea ports. For the nomadic Ababda, for example, trade in senna provides a significant source of income.

Names and taxonomy

S. alexandrina is also known under the names Egyptian Senna, Tinnevelly Senna, East Indian Senna or the French sene de la palthe

It received the names "Alexandrian Senna" and "Egyptian Senna" because Alexandria in Egypt was the main trade port in past times. The fruits and leaves were transported from Nubia and Sudan and other places to Alexandria then from it and across the Mediterranean sea to Europe and adjacent Asia.

Though it might look like a scientific name, Cassia Officinalis is actually the apothecary term for this plant, and hence Officinalis - the Latin adjective denoting tools, utensils and medical compounds - is written with a large "o", unlike in specific names which are always written small today.

Uses

Medicinal

Modern medicine has since at least the 1950s[2] used S. alexandrina as a laxative.[3][4] If accidentally ingested by infants, it can cause side effects such as severe diaper rash.[5] The active ingredients are several senna glycosides[6] which interact with immune cells in the colon.[7]
