know that even codeine often fails. It has impressed 

 me, after trial in a number of cases, that drosera is 

 worthy of use in these cases. It often fails; so do 

 other remedies recommended for irritable cough in 

 which examination reveals no lesion capable of ac- 

 counting for the persistent "barking" cough. 



DUBOISINE 



This alkaloid is almost identical with hyoscy- 

 amine, the dose of its sulphate being 1-100 to 1-60 

 grain. It is also a mild mydriatic in 0.2 to 0.8% 

 solution. 



DULCAMARA 



BITTERSWEET, Solanum dulcamara. Official in 

 Austria, France, Mexico, and Spain. Solanine, a 

 narcotic, exists in small quantities in dulcamara. 



The drug produces a certain amount of cerebral 

 disturbance, with dryness of the throat, and some 

 erythema at times. It is irregularly diuretic. The 

 drug possesses the common influences of the night- 

 shades, though only to a slight degree. Hence it 

 resembles belladonna therapeutically. It may be 

 used in rhinitis and other conditions associated with 

 "colds" due to exposure, and in acute tracheo-bron- 

 chitis and mild pulmonary affections. It may be 

 given in fairly full dosage in myalgia, with, of course, 

 eliminants. It has some reputation in the treatment 

 of psoriasis and pityriasis. Dose: fl. 10 minims to 

 one fluidrachm. 



This drug was formerly official in the U. S., but 

 it dropped out of use. Really it has never been 

 accurately determined just what place it should 

 occupy in therapeutics.
