to Roxburgh) Flor. Ind., vol. i. 141', the juice of the leaves, 
conjoined with petroleum, is used in India as a local applica- 
tion in rheumatism. Whatever benefit is derived from this 
formula is dobutless due to the petroleum (Ph. Ind.). 
A teaspoonful of the juice of the leaves given to. infants 
suffering from catarrh or severe bronchitis gives relief by 
causing vomiting and purging. <Dr. U. C. Dutt, in Watt’s 
Dictionary). 
In Pondicherry It is considered to be aphrodisiac, and in 
Ceylon, under the name of Loonoowela, it is prescribed in fevers. 
For tlie analysis the wholo plant was used, dried at a low temperature 
and exhausted with 80 per cent, alcohol. The alcohol (reed extractive was 
then agitated with petroleum ether ; ether from an acid solution, and again 
with ether from an alkaline solution, and finally with chloroform from 
an alkaline solution. Operating in this manner, a trace of oily matter 
was obtained, soluble In alcohol with acid reaction ; two resins, one easily 
soluble in ether, the other soluble with difficulty, but both soluble in 
alkaline solutions and reprecipitated by acids; an organic acid, and a 
tannin affording a green coloration with ferric chloride. An alkaloidal prin- 
ciple was also isolated, soluble in ether and in chloroform, and affording a 
cherry red coloration in the cold with Frehde's reagent. No other reactions 
were noted. (Pharmacographia Indica, III. 9).

Use . — It is used as a febrifuge. 
The bitter febrifuge Curangin, C 43 H 77 O 20 , may be extracted by means 
of ethylacetate. This glucoside is easily soluble in ethyl or methylalcohol, 
or in acetone or ethylacetate containing water ; 100 parts of water dissolve 
0-18 part. The solutions are neutral. When heated at 100°, curangin loses 
7-10 per cent of water, but the residue regains this amount on exposure to 
air. By the action of benzoyl chloride and sodium hydroxide solution, it forms
