In some languid habits, the fluor albus returns periodically, instead of the proper menstrual evacuation, until the patient’s constitution is duly invigorated. _Causes._ It may be produced by any cause which either weakens or irritates the womb and its appendages. It may arise from general debility of the constitution, but it is especially caused by circumstances impairing the power of the womb itself, as, for instance, a severe labour, a miscarriage, or profuse menstruation. In some instances it appears to depend on a full and irritable habit of body, and, in other cases, of local irritation, such as disorders of the womb, or of the urinary organs, or a collection in the gut, of the small thready worms called ascarides. Upon the high authority of Dr. Hamilton, this disease is most frequently first brought on by some imprudence in respect to diet and clothing, or exposure to cold or fatigue, or neglect of the bowels about the time when menstruation begins. _Treatment._ In the treatment of this complaint regard must be had to the apparent cause, and to the state of the patient. The discharge is too often considered by the sex as the effects of general weakness in their habit, and, therefore, they are led to the indiscriminate use of heating medicines, as port wine, balsam copaibæ, &c., without paying attention to the habit of the body, or cause of the disease. A milk diet, change of air, and the partial cold bath, as sponging the loins and thighs with cold water every morning, with attention to cleanliness and proper exercise, are often sufficient to arrest the disease, if early adopted. In addition to this plan of treatment, if the patient be of a full habit, a disposition to fever from slight causes, attended with a sense of heat about the passage to the womb, it will be necessary to have recourse to the lancet, cooling cathartics, and febrifuge medicines, and to inject, several times a day, flax-seed tea or milk and water, into the passage of the womb. In the great majority of cases, the complaint arises from general debility or laxity of the vessels of the parts, and in such cases the indications of cure are to increase the vital heat, promote the digestion, and restrain the preternatural discharge. In order to which, recourse must be had to such of the tonic medicines as will be found to agree best with the patient. Of these, the bark and elixir vitriol, the tonic powders or pills, the rust or tincture of steel, and lime-water have usually been employed, and often with good effects. In some instances, however, I have known these medicines to fail, when the nitric acid, diluted, in doses of a wineglassful, three or four times a day, wonderfully succeeded.
