This is a very serious illness. In the case of recovery, the patient ought to abstain from taking any heating aliment for one hundred days. 7. _Tsee-kin-tong_ or _tsee-ly-tong_. Gums swollen; slight but continuous pain, aggravated by the effort of the wind; the gums become ulcerated little by little, with discharge of purulent and sanguine mucus; and the root of the tooth is afterward seen to be uncovered. This malady is to be treated by means of draughts, pills, mouth washes, and frictions of various kinds. After the treatise on the maladies referred to above, we find in Dabry’s book a long series of “general remedies for every kind of toothache.” There are about forty of these, and decoctions and powders predominate among them, the latter to be rubbed on the painful spot. Decoctions are the form of medicament most in use among the Chinese. In this list of about forty anti-odontalgic remedies we find as many as eighteen decoctions, seven for internal use, and the others to be employed as mouth washes. Some of the latter are compounded with vinegar instead of with water. Four remedies of the above list are to be made into a paste and formed into pills, to be applied upon the aching tooth. Another medicament is also to be formed into pills and applied inside the ear. The following remedy is particularly worthy of note: “One roasts a bit of garlic, crushes it between the teeth, and afterward mixes it with chopped horseradish seeds, reducing the whole to a paste with human milk; one then forms it into pills; these are to be introduced into the nose on the side opposed to that where the pain is situated.” Two other remedies, in powder, are to be snuffed up through the nose. A powder to prevent the progress of caries is prescribed, with which the tooth should be rubbed every day, or it may be applied on the decayed spot. Finally, two powders are also prescribed for whitening the teeth. One of these is compounded of seven ingredients, among which is musk; the other has only three substances in its composition: salt (gram 25), musk (gram 1.8), _tsang-eul-tsee_ (gram 36). A therapeutic method much in vogue among the Chinese is acupuncture, which is used in the treatment of the greatest variety of affections, including those of the dental system. The doctors of the Celestial Empire have the greatest faith in this operation, which they hold capable of removing obstacles to the free circulation of humors and vital spirits, thus reëstablishing that equilibrium of the organic forces which constitutes health, and the absence of which causes disease. The Chinese doctors prefer to use gold or silver needles for puncturing; but they also frequently use needles of the best steel. These instruments vary very much in length, in thickness, and in form, and there are not less than nine distinct kinds of puncturing needles.
