GENERAL ANALYSIS.

The general action of Merc. cor. is essentially the same as of other Mercurial preparations, yet it offers peculiarities of its own, which are found in no other. It is, as the name indicates, a highly corrosive, irritating poison, acting pre-eminently upon mucous membranes with destructive energy, producing an intensely acute inflammation, rapidly tending to softening and gangrenous disorganization. Its irritant influence also extends to the serous membranes, especially to the peritoneum. The most essential feature of Merc. cor. is the phagedenic tendency of all inflammatory conditions.
