Materia Medica

Tonics

employ'd it with advantage in intermittants = it is not verry bitter.

Cornus Sericea or Red
Dogwood. It grows in our medows and promises to be one of
our most valuable articles in medicine, the bark is more bitter
than the other dogwood. It was used during the american
revolution as a substitute for Cinchona and was found to
answer extremely well. I have now finished the vegitable
tonics, and shall proceed to mention those derived from
the mineral kingdom = They form the most important
articles in the class of tonics.

Iron. I shall pass over
the natural history of Iron and confine myself to those
preparations used in medicine. Those most used in medicine
are first Limatura ferri, Croacus Martis and Rubeg ferri
and oxyde, this Rubeg ferri is the most important preparation
of Iron that we have, 2d in form of a salt as the sulphate
of Iron, Flores Martiales is made by subliming one pound
of the muriate of Ammonia and ℥i [1 ounce] of steel filings, the
dose of this preparation is from 4 grs [4 grains] to ℈i [1 scruple]. It is best given in
the form of a bolus, otherwise it will be apt to produce nausea
