them up and cut off the roots, beginning at one end of a See also:row
.
From See also:October to See also:March the seeds. should be sown thickly in shallow boxes and placed in a warm See also:house or See also:frame, with a temperature not below 650
.
Brassica See also:nigra occurs as a See also:weed in See also:waste and cultivated ground throughout See also:England and the See also:south of See also:Scotland, but is a doubtful native
.
It is a large branching See also:annual 2 to 3 ft. high with stiff, rather rough, See also:stem and branches, dark See also:green leaves ranging from lyrate below to lanceolate above, See also:short racemes of small See also:bright yellow See also:flowers one-third of an See also:inch in See also:diameter and narrow smooth pods
.
B. See also:alba is more restricted to cultivated ground and has still less claim to be considered a native of See also:Great See also:Britain; it is distinguished from See also:black See also:mustard by its smaller See also:size, larger flowers and seeds, and spreading rough hairy pods with a See also:long curved See also:beak
.
The See also:peculiar pungency and odour to which mustard owes much of its value are due to an essential oil See also:developed by the See also:action of See also:water on two peculiar chemical substances contained in the black See also:seed
.
These bodies are a See also:glucoside termed by its discoverers myronate of See also:potassium, but since called sinigrin, C1oH18KNS2010, and an albuminoid See also:body, myrosin
.
The latter substance in presence of water acts as a ferment on sinigrin, splitting it up into the essential oil of mustard, a potassium See also:salt, and See also:sugar
.
It is worthy of remark that this reaction does not take See also:place in presence of boiling water, and therefore it is not proper to use very hot water (above 120° F.) in the preparation of mustard
.
The explanation is that myrosin is decomposed by water above this temperature
.
Essential oil of mustard is in chemical constitution an isothiocyanate of allyl C3H,NCS
.
It is prepared artificially by a See also:process, discovered by Zinzin, which consists in treating bromide of allyl with thiocyanate of ammonium and distilling the resultant thiocyanate of allyl

white mustard contains in place of sinigrin a peculiar glucoside called sinalbin, CnH44N2S2Oi8, in several aspects analogous to sinigrin
.
In presence of water it is acted upon by myrosin, See also:present also in white mustard, splitting it up into acrinyl isothiocyanate, sulphate of sinapin and See also:glucose
.
The first of these is a powerful rubefacient, whence white mustard, although yielding no volatile oil, forms a valuable material for plasters
.
The seeds of Brassica juncea have the same constitution and properties as black mustard, as a substitute for which they are extensively cultivated in See also:southern See also:Russia; the plant is also cultivated abundantly in See also:India
.
Both as a table condiment and as a medicinal substance, mustard has been known from a very remote See also:period
.
Under the name of ran; it was used by See also:Hippocrates in See also:medicine
.
The See also:form in which table mustard is now sold in the See also:United See also:Kingdom See also:dates from 1720, about which See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O.

mill and sifting the See also:flour from the husk
.
The bright yellow See also:farina thereby produced under the name of " Durham mustard " pleased the See also:taste of See also:George I., and rapidly attained wide popularity
.
As it is now prepared mustard consists essentially of a mixture of black and white farina in certain proportions
.
Several grades of pure mustard are made containing nothing but the farina of mustard-seed, the See also:lower qualities having larger amounts of the white cheaper mustard; and corresponding grades of a mixed preparation of equal See also:price, but containing certain proportions of wheaten or See also:starch flour, are also prepared and sold as " mustard condiment." The mixture is See also:free from the unmitigated bitterness and sharpness of flavour of pure mustard, and it keeps much better
.
The volatile oil distilled from black mustard seeds after maceration with water is See also:official in the See also:British Pharmacopeia under the See also:title Oleum sinapis volatile
.
It is a yellowish or colourless pungent liquid, soluble only in about fifty parts of water, but readily so in See also:ether and in See also:alcohol
.
From it is prepared, with camphor, See also:castor oil and alcohol, the linimenturn sinapis
.
The official sinapis consists of black and white mustard seeds powdered and mixed
.
The See also:advantage of mixture depends upon the fact that the white mustard seeds have an excess of the ferment myrosin, and the black, whilst some-what deficient in myrosin, yield a volatile body as compared with the fixed product of the white mustard seeds
.
From this mixture is prepared the charta sinapis, which consists of See also:cartridge See also:paper covered with a mixture of the See also:powder and the liquor caoutchouc, the fixed oil having first been removed by benzol, thus rendering the glucoside capable of being more easily decomposed by the ferment
.
Used internally as a condiment, mustard stimulates the salivary but not the gastric secretions
.
It increases the peristaltic movements of the See also:stomach very markedly
.
One drachm to See also:half an See also:ounce of mustard in a tumblerful of warm water is an efficient emetic, acting directly upon the gastric sensory nerves, long before any of the See also:drug could be absorbed so as to reach the emetic centre in the medulla oblongata
.
The See also:heart and respiration are reflexly stimulated, mustard being thus the only stimulant emetic
.
Some few other See also:emetics See also:act without any appreciable depression, but in cases of poisoning with See also:respiratory or cardiac failure mustard should never be forgotten
.
In contrast to this may be mentioned, amongst the See also:external therapeutic applications of mustard, its frequent See also:power of relieving vomiting when locally applied to the epigastrium
.
The uses of mustard leaves in the treatment of See also:local pains are well known
.
When a marked See also:counter-irritant action is needed, mustard is often preferable to See also:cantharides in being more manageable and in causing a less degree of vesication; but the cutaneous damage done by mustard usually takes longer to heal
.
A mustard sitz See also:bath will often hasten and alleviate the initial See also:stage of menstruation, and is sometimes used to expedite the See also:appearance of the eruption in See also:measles and scarlatina
.
The domestic remedy of hot water and mustard for See also:children's feet in cases of See also:cold or threatened cold may be of some use in See also:drawing the See also:blood to the See also:surface and thus tending to prevent an excessive vascular See also:dilatation in the See also:nose or bronchi
.
The proportion of an ounce of mustard to a See also:gallon of water is a See also:fair one and easily remembered
.
But by far the most important therapeutic application of mustard is as a unique emetic
