orrosive humours of disease or acrimonious
medicines; the ureters from sharp, choleric, or acid urine, and
lubricate the passage for the stony gravel. Their crude parts cool the
heat of scorbutic blood, lessen its violent motion, and sheathe its
acrid saline particles.

By their different mucilaginous principles they produce the following
various salutary effects:

The earthy repel and cool outward inflammations.

The watery, which is thick and gummose, stop fluxes and correct sharp
humours.

Those of an oily odour alleviate pains.

Those of a pungent acrid dissolve tartareous concretions in the
kidnies.

From these and a variety of other salutary properties, it is evident
the general nature of Dr. Solander's tea is such as to correct acrid
humours, promote the secretions, restore the equilibrium between the
fluids and solids, and finally to brace every part of the relaxed
nervous system. The body being thus relieved from obstructions, its
circulations restored, the digestive faculties invigorated, and the
spirits re-animated, the debilitated constitution is reinstated in all
its enjoyments of health and hilarity. It may be therefore observed,
that the principle of this tea is to nourish as a general aliment,
while it renovates the human constitution, without having recourse to
the nauseous portions of galenical preparation, or the hazardous trial
of chalybeate waters. As this tea is particularly salutary in all cases
where mineral waters are generally recommended, it is very proper the
Public should be cautioned against the danger which too frequently
attends the constant drinking of them.

Chalybeate waters, it must be acknowledged, have effected very
extraordinary cures in certain cases. But when so great an author as
Helmont says, that such waters are fatal to all those who are afflicted
with peripneumonic complaints, it is surely necessary they should be
resorted to with the greatest caution; and even in complaints where
they may be serviceable, it is necessary to observe whether they really
possess those chalybeate qualities for which they are commended. Those
who have written upon their virtues assert, and with seeming propriety,
that where they deposit an ochreous sediment, they are certainly
dispossessed of their steely virtues; for ochre being no other than the
calx of iron, such a residue evinces the evaporation of the more
eminent properties of the chalybeate, by the phlogiston of the mineral
