Emplastrum Galbani Compositum. L.D. Emplast: Gummos. E. More powerful than the preceding plaster. In indolent glandular enlargements of a strumous character, in fixed and long continued pains in the neighbourhood of the joints, or in anomalous or arthritic pains of the ligaments, this plaster is said to be frequently beneficial.
Emplastrum Hydrargyri. L.E. The mercury in this plaster is in the state of oxidation ad minimum; each drachm containing about fifteen grains of mercury, (sixteen grains, Edinb.) It is alterative, discutient, and sometimes sialogogue; but it is inferior to the Emplast: Ammoniac: cum Hydrargyro.
Emplastrum Opii. L.E. This plaster is supposed to be anodyne, but it is very doubtful whether the opium can, in such a state, produce any specific effect. See Form: 5.
Emplastrum Picis Compositum. L. Emplast: Picis burgundicæ, P.L. 1787. It is stimulant and rubefacient, and is often employed as an application to the chest, in pulmonary complaints; the serous exudation however which it produces, frequently occasions so much irritation that we are compelled to remove it.
Emplastrum Plumbi. L. Emplast: Oxydi Plumbi semi-vitrei. E. Emplast: Lythargyri. P.L. 1787. Emplast: commune, 1745. Diachylon[[496]] Simplex, P.L. 1720. This is a very important plaster, since it forms the basis of a great many others; under the name of Diachylon it has long been known, and employed as a common application to excoriations, and for retaining the edges of fresh cut wounds in a state of apposition, and at the same time for defending them from the action of the air; when long kept it changes its colour, and loses its adhesive properties, and by high temperature the oxyd of lead is revived.[[497]]
Emplastrum Resinæ. L. Olim, Emplast: commune adhæsivum, P.L. 1745. Emplast: Resinosum. E. Emplast: Lithargyri cum Resina. D. It is defensive, adhesive, and stimulant.[[498]]
