In ordinary tonsillitis, and even in suppuration about the fauces, I have seen much advantage from small doses of hydrarg. c. creta. In early stages of quinsy, in ulcerated sore throat, and even in the "putrid" form (cynanche maligna), 1/2 gr. given every two to four hours has induced rapid improvement. It does not exclude the use of aconite or belladonna if indicated by high temperature or much pain. In parotitis ("mumps"), also in glossitis, "cancrum oris," and cracks and ulcerations about the mouth and lips, the same treatment is very effective. For relaxed congested conditions of the faucial membrane the value of dilute solution of mercurial nitrate has been already indicated.
