About

Senna didymobotrya is a species of flowering plant in the legume family known by the common names African senna, popcorn senna, candelabra tree, and peanut butter cassia. It is native to Africa, where it can be found across the continent in several types of habitats.

It has been introduced to many other parts of the world for use as an ornamental plant, a cover crop, and a leguminous green manure. In some places it is now naturalized in the wild, for example, in parts of Indonesia, Australia, Mexico, and the United States in California, Florida, and Hawaii.

Uses

In Kenya, some cultures, particularly Kalenjins, use the plant to prepare a special type of sour milk (mursik) which is used mainly during festivities. A sizeable tree is cut and its branches pruned. The bark is mostly removed, then dried. Once the bark is dry, and the specially made calabash gourd, or Sotet, has been cleaned and dried, the senna bark is put in a fire, and removed when charred. The process emits fragrant smoke. The charred bark is used to coat the inside of the gourd, which is subsequently used for the storage of fermented or fresh milk.
