ON LOBELIA INPLATA.

the acetic acid has been added, for forty eight hours, and then 
throw the whole on a displacement filter, and after the liquid 
has ceased to pass, add sufficient diluted alcohol, that four 
pints of tincture shall be obtained. Evaporate this by means 
of a water bath, until it attains the consistence of an extract. 
The product thus obtained is about one-eighth of the seed em- 
ployed. In this form (as a pill) Lobelia can be administered 
without that peculiar disagreeable effect upon the fauces, so 
characteristic of its exhibition in the form of tincture. 
Vinegar of Lobelia inflata. 
Take of Lobelia, in powder, four ounces. 
Diluted Acetic Acid or distilled Vinegar, a pint and a half. 
Macerate the Lobelia in the dilute acid, for twelve hours, 
and subject it to displacement on a proper filter, until twenty- 
four fluid ounces are obtained. 
Syrup of Lobelia in flat a. 
Take of Vinegar of Lobelia, six fluid ounces. 
Sugar, twelve ounces* 
Dissolve the sugar in the vinegar, by the aid of heat, remove 
the scum which rises, and strain. 
The oxymel may be prepared from the vinegar in the same 
manner as oxymel of squills ; and a combination of the two 
has been highly spoken of by a physician of_ this city, in ca- 
tarrhal affections. 
In making an infusion of Lobelia, some acid — vinegar, for 
instance — should always be added.
