MERCUROUS CHLORIDE – CALOMEL – Hg2 Cl2.
Most of the pathogenetic symptoms were obtained from toxic doses, and perhaps on that account there are but few conditions to which we need call your especial attention to the remedy.
In the eyes we must remember Mercurius dulcis in scrofulous ophthalmia (76) and ulcerations of the cornea (77).
It is a valuable remedy for catarrhal conditions of the Eustachian tube and middle ear (63), with stoppage of the Eustachian tube and deafness. So frequently is it used in this condition and so much relief does if afford, that it has been called the Eustachian catheter.
In the bowels Mercurius dulcis has the excoriating green stools, green as grass (59), associated with the enlarged glands, ulcerated mouth, offensive ptyalism (163), etc., of mercury, but differing in one important particular, there being little or no tenesmus. it is frequently called for in the diarrhoea of infants.
I use Mercurius dulcis 3d.
