The glands and hairs from the capsules of Mallotus 

 ■ philippinensis (Lamarck) Mueller Arg. (nat. ord. Euphor- 

 biacese). 



Habitat. — India, China and the Philippine Islands. 



Properties. — A granular, mobile, brick-red or brownish- 

 Ted powder, inodorous and nearly tasteless ; imparting a 

 •deep red color to alkaline liquids, alcohol, ether or chloro- 

 form, and a pale yellow tinge to boiling water. Under the 

 microscope it is seen to consist of stellately arranged, color- 

 less hairs, mixed with depressed-globular glands, containing 

 numerous red, club-shaped vesicles. 



Constituents. -^ The chief principle is (1) rottlerin, 

 '(CjjH^jOs), occurring in yellow acicular crystals, soluble in hot 

 alcohol, ether, benzol, and carbon disulphide. There are 

 also (2) resins, 80 per cent. 



Dose.— D., 3ss.-ii. (2.-8.); H. & C, §i. (30.). 



Action and Uses. — Kamala is an anthelmintic. It is 

 employed more frequently as a tseniacide, but will also kill 

 ascarides and oxyurides. Large doses may give rise to 

 nausea and vomiting in dogs and cats. Kamala is also a 

 purgative, so that it is rarely necessary to employ one after 

 its administration. It should be given in syrup to the fast- 

 ing animal, and repeated in eight hours if the first dose is 

 not operative by that time.
