In the astringent, the acid fixing upon the more earthly parts, the nutritious oil is more easily separated, which renders them also pectoral, cleaning, and diuretic. This part of the tea is in its nature particularly serviceable in all cases where vulnerary medicines are requisite. They particularly amend the acid in the nervous juice, and thus restore the equal motion of the spirits, which were obstructed or retarded by spasms or convulsions. By the volatile oil and volatile pungent salt, obstructions are opened, and the motions of the languid blood increased to a healthy degree of circulation. They resolve coagulated phlegm in the stomach, preserve the fluidity of the juices, and promote digestion, by assisting the bile in its operation. And with regard to their balsamic and aromatic nature, these qualities warm the stomach and expel wind, by rarefying the flatuous exhalations from chyle in the prima viae. These, by their sweetness, allay the sharpness of rheums, and lenify their acrimony. Being filled with an oily salt, they open the passage of the lungs and kidnies. By opening the pores, they extraordinarily discuss outward tumours, and attenuate the internal coagulation. All these virtues may be said to be derived from the union of their balsamic oil and volatile salt. By a second class of aromatics, with which Dr. Solander composed this sanative tea, is such as have a bitter astringency joined to their volatile oil and salt. These united qualities correct acids in the stomach, cleanse the lungs, and open obstructions in the glands caused by coagulated serum; and the saline pungent oil altering the acids in the glands of the brain, by correcting and attenuating its lympha and succus nervosus, produces the same effect; for the lympha and nervous juice are, like other glandulous humours, liable to acidity and stagnation; therefore these aromatics, by exciting their motion and correcting their acidities, render the liquids of the nerves more volatile, and are therefore justly termed cephalics. And as it is the property of volatiles to ascend, the reason is evident of the brain being assisted by their salutary qualities. These aromatics likewise evacuate serum from the blood, promote its circulation, and attenuate the coagulations of chyle, lympha, and succus nervosus. And here, it is proper to add, that all aromatics, by rarefying the blood, are cordial. There being aromatic astringents in this tea, its infusion strengthens the fibres and membranes of the stomach, and all the nervous system, in such a manner as not to destroy their tensity by that too great contraction caused by the foreign teas; and, having no acid in their astringency, the blood is preserved from too great a rarefaction, which would otherwise happen from the pungency of their oily qualities. These also excite the appetite, by stimulating the natural progress of the chyle, and thus prevent its too rapid fermentation of its spirituous parts into windy flatulencies.
