posed that daturine is a mixture of atropine and hyoscyamine. 

 The seed contains about 0.3%, the leaves 0.2% of alkaloids. 



Antagonists, Incompatibles and Synergists, are the same as 

 for Belladonna. Morphine or opium in full doses are the best 

 physiological antidotes. Pilocarpine hypodermatically is also 

 very good. Tannic acid may also be used. 



Physiological Actions. — It is like belladonna in almost every 

 particular, but stramonium is more powerful and acts chiefly on 

 the sympathetic system, not affecting the motor or sensory nerves ; 

 in large doses it causes a greater degree of cardiac irregularity 

 and a more furious delirium ; it has a special affinity for the gen- 

 erative organs, quieting the sexual passion ; it dilates the bronchii 

 in asthma, much more than does belladonna. 



Uses. — To relieve pain, spasmodic affections, asthma or asth- 

 matic heaves, spasmodic colic, nymphomania (unsatisfied or ex- 

 cessive sexual desire in the female). In asthma in dogs or heaves 

 in horses, combine it with gelsemium and lobelia and follow 

 up with Fowler's Solution of arsenic ; for irritable ulcers and piles, 

 combine the official ointment of tannic acid with ointment of 

 stramonium and cerate of subacetate of lead. Stramonium is 

 useful in spasms of the sphincter vesica.
