1371. Mercury Has Long Held A High Repute In The Treatment Of Acute Inflammations

These are often found to yield in a remarkable manner when the system is brought under the influence of the remedy. The effect of Mercury in acute inflammations may be partly ascribed to its power of increasing the secretions and influencing the capillary circulation, partly to its influence in promoting the absorption of morbid products, and partly to its effect on the constitution of the blood. It is of most value in sthenic inflammations accompanied by the effusion of lymph. In low asthenic inflammations, and in those of a scrofulous and erythematous type, it is generally positively injurious. It has more effect in controlling inflammation of serous than of mucous membranes, and in that of the parenchyma of the liver than of the lungs. $ Its value in rheumatic inflammation is differently estimated by different observers, but the balance of evidence is in its favour in rheumatic inflammations of the heart, In Chronic Inflammation it is of service in removing fibrinous and other morbid products.
