Scrofulous children are often disfigured by a chronic swelling of the upper lip and alae nasi, which may be connected with a crack or fissure on the inner surface of the mucous membrane. Accompanying this condition, there often exists a tendency to dyspepsia and indolent swelling of the mesenteric, cervical, and other glands.
Although we cannot wholly cure the constitutional tendency in such cases by sulphide of calcium, yet I have seen their general condition greatly improved by small doses (1/4 gr.) given night and morning for a few weeks; the fissure has healed and the lip-swelling subsided, and the glands have grown less.
In cases where pus has actually formed in some of the glands, the effects of this remedy may readily be traced in the subsidence and disappearance of some of the swellings, while others progress quickly, maturate and discharge, and others that have been open and discharging unhealthily for some time take on healthy action, and ultimately contract and heal. For permanent good results this treatment should be followed up by cod-liver oil and generous diet, and, if possible, change to the seaside. As a rule, frequent doses of the sulphide are not desirable, as they are apt to derange the stomach and cause troublesome eructation of sulphuretted hydrogen.
