occasionally used as a snuff in catarrh with headache. (U. C. 

 Dutt.) It is also used by Hindus at the present day, mixed 

 with, ginger, as a rubefacient application in cholera, &c, and 

 according to Irvine, kaiphal and ginger mixed, is the best 

 substance that can be employed for this purpose. Dymock 

 writes, " Muhamtnadan writers tell us that the bark is resol- 

 vent, astringent, carminative and tonic ; that it cures catarrh 

 and headaches; with cinnamon they prescribe it for chronic 

 cough, fever, piles, &c. Compounded with vinegar, it strength- 

 ens the gums and cures toothache ; an oil prepared from it 

 is dropped into the ears in earache. A decoction is a valuable 

 remedy in asthma, diarrhoea, and diuresis ; powdered or in the 

 form of lotion, the bark is applied to putrid sores : pessaries 

 made of it promote uterine action. The usual dose for internal 

 administration is about CO grains. Dahn-el-handul, an oil pre- 

 pared from the flowers, is said to have much the same properties 



as the bark." 



The ground bark yields a coloring principle, named Myricetin. The yield 

 of coloring matter from 100 grams of bark averaged from 0*23 to 0'27 gram. 

 Its formula is C 1S H 10 8 . Its points of similarities to, and differences from, 

 other coloring principles are given in the following table :—
