Introduction
Senna (Cassia Augustifolia, also known as Tinnevelly Senna or
Senna Alexandrina) is a small semi-desert
shrub that is cultivated in Africa, India and southern
China. A description of the medicinal properties was
first recorded by Arabian physicians in the ninth century. |
|
| Today,
senna is well known around the world and listed in the
national pharmacopeias of countries like China,
England, France, Germany, India, Japan, Russia, and the
United States. Senna is still mainly used as a
natural, gentle laxative. |
