576 MUSTARD 



ACTIONS AND USES. Quassia is a bitter stomachic and 

 tonic. It resembles gentian and calumba. It is prescribed 

 for the several domestic animals in dyspepsia, loss of 

 appetite, and convalescence from debilitating disorders. 

 Although it has no appreciable vermicide effect when given 

 by the mouth, when used as an enema it destroys both 

 ascarides and lumbrici. Large doses are irritant. The 

 infusion is a narcotic poison for flies and other insects, and 

 is used as a parasiticide in skin diseases. 



DOSES, etc. The B.P. infusion, prepared by macerating 

 one part of chips for fifteen minutes with one hundred parts 

 cold water, is administered alone, or with salines, acids, or 

 iron salts, with which, unlike most vegetable bitters, it 

 mixes without decomposition or discoloration. Of the 

 infusion, horses and cattle take fij. to fiv. ; sheep and 

 pigs, f3iv. ; dogs, f3J. The tincture is not used by 

 veterinarians.

The mustard plants are annuals, one to two feet high, 

 with yellow cruciform flowers, and pods containing several 

 brown seeds. They are indigenous in most parts of Europe 

 and extensively cultivated in Durham, Yorkshire, and Lin- 

 colnshire. An abundant wild variety, familiarly known as 

 charlock and kellocks, is sometimes used for adulterating 

 the better sorts. The black mustard seeds are red or 

 greyish-brown, about the size of millet ; the greenish-yellow 

 powder has a pungent oily taste, and when triturated with 

 water yields a pungent odour. The white mustard seeds 

 are double the size of the black, and lighter in colour. 

 Inodorous when entire or powdered, and almost inodorous 

 when triturated. 



Black and white mustard seeds contain about 25 per cent, 

 of a yellow, tasteless, non-drying fixed oil, similar to that of 

 rape, and consisting of olein, stearin, and glyceride of erucic 

 or brassic acid ; 20 per cent, of mucilage, chiefly found in
