Remarks

Ammoniac as an external application has long been credited with power of discussing certain indolent and scrofulous tumors. It it usually employed in the form of the officinal Emplastrum Amnoniaci or in conjunction with mercury in the Emplastrum Ammoniaci cum Ilydrar-gyro. The latter is generally supposed to be more efficient than the former, but if applied to an extensive surface may induce ptyalism and other symptoms of mercurial intoxication.
