curved, usually softly pubescent, membranous, hairs of mouth 

 as long as the teeth ; teeth very short, subulate scabrid. Flowers 

 lin. long, says Collett from Simla. Calyx hairy near the top, 

 otherwise glabrous. 



Uses : — The plant is officinal, being considered stimulant 

 and diaphoretic (Stewart). The seeds yield an oil which is 

 used medicinally by the Santals (Revd. A. Campbell). The 

 fresh juice is used in certain localities as an external application 

 in scabies. The flowers are administered in the form of a syrup 

 as a domestic remedy for coughs and colds. 



It is also used as a vegetable rennet.

An erect annual, pubescent or hispidly hairy herb. Stem 

 l-3ft., branched above. Hairs spreading, deflexed or adpressed. 

 Leaves 2-3in., sometimes lin. diam., linear or elliptic-lanceolate, 

 obtuse, sub-serrate, shortly petioled. Whorls small, J-f in. diam., 

 sub-terminal many-fid, rarely axillary. Bracts few, ciliate. 

 Calyx very constant in size and shape, i-fin., obliquely turbinate 

 glabrous, scabrid or sparsely hispid ; teeth minute, erect or 

 spreading horizontally. Mouth broad pubescent within. 



Uses :— The Cinghalese attribute miraculous powers to 

 this plant The leaves are bruised and a teaspoonful of the 

 juice given, which is snuffed up by the natives as a remedy 

 in snake-bites. The fresh juice is also employed in headache 

 and colds (Long, Ind. Plants of Bengal). In Reunion, it is con- 

 sidered to be stimulant and antirheumatic. 



Chemi. com.— The herb of L. zeylanica on distillation afforded a very 

 small quantity of essential oil. By boiling a decoction of the herb with 

 soda solution a strong odour was given off, and on condensing the vapour, 

 ammonia and a volatile alkaloid were detected in the distillate. The alkaloid 

 was combined in the plant with an acid giving a green colour with ferric 

 salts. The air-dried plant afforded 7 3 per cent, of ash (Pharmacog. Ind. Ill 

 124.).
