Mondo shtuff from around the internet, all about ESCHAR!
My botty best at summarizing from Wikipedia: an eschar (; Greek: eschara) is a slough or piece of dead tissue cast off from the surface of the skin . it is also seen in gangrene, ulcer, fungal Eschar may be allowed to slough off naturally or it may require surgical removal . if eschar is on a limb, it is important to assess peripheral pulses to make sure blood and lymphatic circulation escharotics have long been used in medicine . in conventional modern practice some still are useful for topical treatment of growths such as warts . escharotic salves now strictly regulated in most western countries, and available on prescription only . some prosecutions have been pursued over unlicensed sales of products such as Cansema.
