former species (the only one grown in India) is fairly extensively pro- 
duced in Tinneveily, and recently its cultivation has been extended to 
Madura and Trichinopoly, districts of South India, and to Poona in 
Bombay. 
(t Indian senna is either exported coastwise to Bombay and thence to 
foreign countries, or is consigned direct from Tuticorin. The drug is 
also imported from Arabia, where it is collected from the wild plant and 
accordingly often much adulterated. It would appear that about 5,00U 
cwt. are usually taken by India and again re-exported under the name 
of East Indian Senna or Moka or Aden Senna, and is thus no doubt the 
true sanna (sona) — kokki (maki) or sanna hajazi. For many years past,, 
however, the imports from Arabia have been declining and the exports of 
Tinneveily senna improving. The purity, high quality and low price of 
the Indian article place it in the front rank.” (Watt, Commercial Pro- 
ducts of India, London, 1908, p. 288).
