If a Gangrene ensueth, Sudorificks must be taken inwardly; such are camphirated Spirit of Treacle, the Essence and Spirit of Elder-Berries, the Spirit of Hart's-Horn with its own proper Salt, Treacle impregnated with the Spirit of camphirated Wine, Scorpion-Water, Hart's-Horn, Citron with Camphire, &c.
As for external Remedies in the beginning of the Gangrene, the Spirit of Wine apply'd hot is excellent; and yet better if Aloes, Frankincense, and Myrrh be intermixt therein. It ought also to be observ'd, that Camphire must always be mingled in the topical Medicines for the Cure of the Gangrene.
A Decoction of unslack'd lime, in which Brimstone hath been boil'd, with Mercurius Dulcis, and the Spirit of Wine, is a very efficacious Remedy.
In a considerable Gangrene, after having made deep Scarifications, let Horse-Dung be boil'd in Wine, and laid upon the Part in form of a Cataplasm. This is an approved Remedy.
If a Sphacelus be begun, scarifie the Part, and apply thereto abundance of Unguentum Ægyptiacum over and above the Ointments and Cataplasms already describ'd; remembring
always, that when the Gangrene degenerates into a Sphacelus, all the mortify'd Parts must be incontinently separated or cut off from the sound.
