518 VEGETABLE DRUGS 



to keep up constant counter-irritation, the drug should be 

 •washed off in 20 or 30 minutes, and the process repeated 

 once in 2 hours. It is unwise to induce much vesication over 

 an extensive surface with mustard, as the result is painful 

 and resolution is slow. Mustard is also serviceable in pain- 

 ful abdominal diseases, as colic, tympanites, enteritis and 

 peritonitis, but oil of turpentine appears here to be more 

 efficient. 



A sinapism (mustard application) over the loins is useful 

 in acute ^nephritis, and will not lead to irritation of the 

 kidneys from absorption which may ensue after cantharidal 

 blistering. Cantharides has, however, a more active, per- 

 manent and revulsant effect in most local inflammatory con- 

 ditions, and is more potent in acute laryngitis. The action 

 of mustard is rapid and fleeting, unless applied continually 

 in considerable strength. For this reason it is indicated to 

 impress the nervous system instantaneously, in opium, 

 alcohol and other narcotic poisoning ; in respiratory failure, 

 in collapse and extreme depression in the course of acute 

 diseases (pneumonia and parturient apoplexy), applied all 

 over the body, or over the cardiac region in syncope. 

 Mustard is of utility in muscular or articular rheumatism, 

 and is employed on swollen glands (strangles), inflamed 

 joints and tendons ; but is usually less efficacious than 

 a good cantharidal -blister in these three latter condi- 

 tions. 



Uses /nferwaZ.— Mustard is an efficient emetic for dogs, 

 in tablespoonful doses, given in a cup of tepid water. It is 

 usually at hand, and not only emptier the stomach in poison- 

 ing, but reflexly stimulates the heart and respiration. If 

 administered for its carminative or stomachic effect, mustard 

 must be given in pill or ball.
