If the slightest external motion alone produces the following changes in the body, what effects may not be ascribed to the constant use of teas, which we find, as before stated, operate internally? A person in perfect health, having his nostrils only touched with a feather, cannot avoid his body being so convulsed as to produce what is commonly called sneezing. But if the number of muscles agitated, the force and straining of the body by sneezing, are considered; the slightness of the cause must excite no little astonishment; for this action is occasioned by the muscles of the scapula, abdomen, diaphragm, thorax, lungs, &c. and if the sneezing continues, an universal explosion of the liquids ensues: tears, mucus, saliva, and urine, are excreted. Thus, without any moist, cold, hot, dry, sulphur, salt, or any other internal or external application, an involuntary motion of all the solids and fluids is produced by a feather touching, in the slightest manner, the inside of our nostrils. But Boerhaave relates further, "That if sneezing continues a long time, as it will by taking one hundredth part of a grain of euphorbium up the nose, grievous and continued convulsions will arise, head-aches, involuntary excretions of urine, &c., vomitings, febrile heats, and other dreadful symptoms; and, at last, death itself will ensue." It is therefore evident that the slightest bodies produce the greatest changes in the human frame. Such is the power of certain particles upon the nerves, that the stomach will be thrown into convulsions that almost threaten an inversion, by taking only four ounces of a wine in which so small a portion of glass of antimony as one scruple is infused in eight pounds of the former. And what is still more remarkable is, that the glass of antimony remains not only undissolved, but, comparatively speaking, undiminished in its weight. These being a few of the fatal afflictions which experience shews to be frequently the consequence of drinking India teas, its injurious nature is too evident to require any further investigation of either their ascribed or positive qualities. The next subject to be considered, relative to India teas, is their Preparation.
