American Tulip bearing poplar.
_Cortex._
[This is a native tree of America, and one of the most magnificent to be
found in our forests—distinguished no less by its great altitude than by
its beautiful foliage. It grows in almost every part of the United
States. The part used in medicine is the Bark. This has a rough, fibrous
appearance and is of a whitish colour. Its taste is bitter, astringent,
and somewhat acrid and aromatic. By analysis, it yields gum, resin,
muriatic acid, iron, mucus, &c. In its action on the system, it is
decidedly tonic, exhibiting at the same time, to a certain extent,
stimulant properties. If given in considerable quantities it acts also
on the skin and kidneys. It has been used with advantage and success in
intermittent fever, chronic rheumatism, gout, hysteria, and in
debilitated states of the stomach. It may be given in substance, which
is the most efficacious form of using it, in doses of from ʒss to ʒij.]
