effect however, though a considerable objection to the employment of 
Toxicodendron, is not peculiar to it, as all the other vegetable poisons are 
liable to the same inconvenience. The dried leaves have been given in 
powder, beginning with half a grain for a dose, repeated three titmes a day, 
or every four hours, gradually increasing the dose to six, or even more 
grains, according to the effects produced. We are told by Dr. Alderson, 
that in some instances the leaves of Toaicodendron have lost five-sixths of - 
their weight in drying, in others, four-fifths : hence, the active properties of 
the powder must vary very considerably. It has also been given in the 
form of tincture* and extract. 
* In the Medical and Surgical Journal for July 1825, p. 82, a case is related, of the 
good effects of the tincture in palsy; a drop night and morning, increasing the dose to 
“ten drops.
