Of The Tulip-Tree
And The Quassia, It Is The Bark Of The Roots That Is Used.
Eminent
febrifuge virtues have also been found in the cortical part of the
roots of the Cinchona condaminea at Loxa; but it is fortunate, for
the preservation of the species, that the roots of the real
cinchona are not employed in pharmacy.
Chemical researches are yet
wanting upon the very powerful bitters contained in the roots of
the Zanthoriza apiifolia, and the Actaea racemosa: the latter have
sometimes been employed with success as a remedy against the
epidemic yellow fever in New York.) Some of these barks so much
resemble each other, that it is not easy to distinguish them at
first sight. But before we examine the question, whether we shall
one day discover, in the real cinchona, in the cuspa of Cumana, the
Cortex Angosturae, the Indian swietenia, the willows of Europe, the
berries of the coffee-tree and uvaria, a matter uniformly diffused,
and exhibiting (like starch, caoutchouc, and camphor) the same
chemical properties in different plants, we may ask whether, in the
present state of physiology and medicine, a febrifuge principle
ought to be admitted. Is it not probable, that the particular
derangement in the organization, known under the vague name of the
febrile state, and in which both the vascular and the nervous
systems are at the same time attacked, yields to remedies which do
not operate by the same principle, by the same mode of action on
the same organs, by the same play of chemical and electrical
attractions?
