occasionally used as a snuff in catarrli 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. Dymoclc 
writes, Muhammadan 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, etc. 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 GO grains. Dakn-el-kandul, 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 0'2S to 0‘27 gram. 
Its formula is C ls H 10 O s . Its points of similarities to, aDd differences from, 
other coloring principles are given in the following table : —
