“ way that it is ready to be carried to the greatest excess, and to 
“ show all the effects of the frequent and large use of narcotics. 
“As it commonly produces a considerable evacuation from the 
“mouth and fauces, so it is the most powerful in relieving the 
“rheumatic affection of toothach. This practice is also the occa- 
“sion of the greatest waste of saliva; and the effects of this in 
“weakening digestion, and perhaps from thence especially, its 
“ noted effect of producing emaciation may appear. 
“ These are the effects of the different modes of employing to- 
** bacco, when it comes to be of habitual use and an article of living. 
* These effects depend especially upon its narcotic power, and cer- 
“tain circumstances accidentally attending its application to the 
“nose and mouth: but as we have observed before, that beside its 
“narcotic, it possesses also a stimulant power, particularly with 
“ respect to the alimentary-canal: by this it is frequent ly employ- 
«ed as a medicine for exciting either vomiting or purging, which 
“it does as it happens to tie more immediately applied to the 
** stomach or to the intestines. 
** An infusion of from half a dram to a dram of the dried leaves, 
“or of these as they are commonly prepared for chewing, for an 
“hour or two, in four ounces of boiling water, affords an emetic 
** which has been employed by some practitioners, but more com- 
“monly by the vulgar only. As it has no peculiar qualities as an 
“ emetic, and its operation is commonly attended with severe sick- 
“ ness, it has not been, nor is it likely ever to come into common 
“ practice with physicians, 
“It is more commonly employed as a purgative in glysters; and, | 
“ as generally very effectual, it is employed in all cases of more 
“ obstinate costiveness; and its powers have been celebrated by 
“© many authors. I have known it to be in frequent use with some 
“ practitioners; and it is indeed a very effectual medicine, but at- 
“ tended with this inconvenience, that when the dose happens to be 
“in any excess, it occasions severe sickness at stomach; and I have 
“known it frequently occasion vomiting.
