One of the simplest things is an alum tampon. You take a piece of absorbent cotton, about the size of a fist, spread it out, put about a tablespoonful of powdered alum on it, fold it up, tie a string around the center, insert it in the vagina as far as it will go, and leave it in for twenty-four hours. Then pull it gently by the string and syringe yourself with a quart or two quarts of warm water. Such a tampon may be inserted every other day or every third day, and I have known many cases where this simple treatment alone produced a cure. In some cases, however, douches work better and the two best things for douching are: tincture of iodine and lactic acid. Buy, say, four ounces of tincture of iodine, and use two teaspoonfuls in two quarts of hot water in a douche bag. This injection should be used twice a day, morning and night. Of the lactic acid you buy, say, a pint, and use two tablespoonfuls to two quarts of water. The lactic acid has the advantage over the tincture of iodine that it is colorless, while the iodine is dark and stains whatever it comes in contact with. Sometimes I order the use of the tincture of iodine and the lactic acid alternately: for one douche the tincture of iodine, for the next the lactic acid, and so on. When the condition improves, it is sufficient to use one teaspoonful of the tincture of iodine and one tablespoonful of the lactic acid to two quarts of water. These injections are quite efficient and have the advantage of being perfectly harmless. One point about the injections: they should be taken not in the standing or squatting position (in which position the fluid comes right out), but while lying down, over a douche pan. The douche bag should be only about a foot above the bed, so that the irrigating fluid may come out slowly; the patient, after each injection taken in the daytime, should remain at least half an hour in bed (in the night time she stays all night in bed). This gives the injection a better chance to come in contact with all the parts of the vagina, and a portion of it comes in contact with the cervix, where it exerts a healing effect. Avoid the use of patent medicines. CHAPTER TWENTY-ONE THE VENEREAL DISEASES Derivation of Word "Venereal"--Three Venereal Diseases--Innocent Contraction of Syphilis Through Various Objects--The Hygienic Elimination of Common Sources of Venereal Infection--Measures for Prevention After Sexual Relations. The word "venereal" means pertaining to sexual intercourse: venereal excess--excess in sexual intercourse; venereal disease--a disease acquired from sexual intercourse with an infected person. The word is derived from Venus (genitive--veneris), the Roman goddess of spring, flowers and Love. There are three venereal diseases: gonorrhea, syphilis and chancroid. Of these, gonorrhea is the most widespread, syphilis the most serious. Chancroid is of comparatively little importance.
