In terms of physical healing during convalescence, what sign points towards the use of Carbo vegetabilis?

Answer

A noted tendency for sores or wounds to heal very slowly or progress toward gangrene

Carbo vegetabilis is often considered when recovery from previous illnesses is proving incomplete or unduly slow, extending into the convalescent phase. This remedy matches the state where restorative processes are severely impaired, which is visible in the slow healing of physical tissues. Specifically, a tendency for sores or wounds to exhibit delayed repair or, in severe instances, even develop gangrenous conditions reflects the deep struggle of the low vital force to initiate and sustain necessary regenerative actions.
