Properties and Uses. This plant is rarely used internally; but is a diaphoretic stimulant quite similar to monarda. The principal use made of it is as an external stimulant and rubefacient, for which purposes its oil is one of the most desirable of all the essential oils. It is much more stimulating than spearmint, more so than hemlock, but not so much so as cloves or cajeput. The Stimulating Liniment and Opodeldoc contain it as an important ingredient; and it is similarly combined with other volatile oils in liniments of all grades of stimulation.

Action, Medical Uses, and Dosage. Oil of origanum is stimulant and rubefacient, and is chiefly employed in the form of liniment as an application to various parts suffering from painful affections. As with many other essential oils, it affords relief in toothache upon being applied to the decayed tooth by means of lint or cotton. It is very seldom administered internally.
