The action of phosphorus in this affection can only be considered palliative; but it can, at least, moderate some troublesome and irritating symptoms. I have used it in various doses in upwards of eight hundred cases of which I have record, and am satisfied that it does not cure advanced tuberculosis, but appears in many cases to arrest its progress, at least for a time; also to improve the condition of the throat and the voice, and to relieve the dry, harassing cough, the pain after food, and even the colliquative diarrhoea and night-sweats. It has also removed pleuritic stitches, and seemed to strengthen the general condition; on the other hand, its use is not free from danger, and requires caution, since it may induce obstinate haemoptysis where there is a tendency to hemorrhage.
Chronic Diarrhoea, in children, with frequent watery evacuations, abdominal pains, depression, and emaciation, or the colliquative form, occurring, e.g., in phthisical adults, has often in my hands yielded quickly to phosphorus. Sometimes it is well to give a few doses of Fowler's solution of arsenic in conjunction with phosphorus.
