It can be grown even in waste lands, there is no need for frequent irrigation and maintenance. It is one of the major medicinal plants exported from India.
But, it is not used much by Indians and it’s consumption is less in India.

About 180 tonnes of Calcium sennosides is produced in India per annum. Out of 180, 140 tonne is exported.

Generally leaf extract is used for laxative preparation. Leaf has higher sennoside content. The young leaves are found to have high sennoside quantity than the matured ones.

Dosage as laxative: 0.5 to 2 grams.

Researches are going on for increasing the sennoside content of senna by applying stress (Plant tissue culture)
