 ternally for dysentery, and in India for the same purpose and 

 as a vermifuge. It is given as a tonic in gastro-intestinal 

 diseases, and General Hardwick has reported good results with 

 it in cholera ; as he reported only two cases, his testimony is 

 not of much value. 



The Chinese use the dry or roasted root, especially in inflam- 

 mation of the viscera and uterine diseases. They also attribute 

 to it diuretic, emmenagogue and anthelmintic properties. In 

 Java and India they use it for gonorrhoea, and in Mauritius as 

 a diaphoretic and astringent. In the Philippines the bruised 

 root is applied to the face for toothache.
