 Aconite. — (Aconitum, U. S.) 



Leaves and root of the Aconitum napellus^ or monkshood, a pe-

 emit a faint narcotic odour. 2\isteo^ the leaves and root, at first bit- 

 terish and acrid, and followed by a peculiar tingling sensation, often 

 amounting to numbness, which extends to the soft palate. 



Effects. — Those of a sedative narcotic, or rather of a benumber^ 

 since it diminishes sensation, causes a feeling of numbness and 

 tincrlinor alono; the extremities, muscular debility, contraction of the 

 pupil, but no delirium or stupor. Poisonous doses cause excessive

 violent vomiting, prostration, great loss of sensibility, but neither 

 coma nor convulsions. It differs from tobacco and digitalis in not 

 producing stupor or giddiness, as a general rule. It yields its virtues
