Hi and thanks for the query, Wound healing in diabetics is generally not as fast as in none diabetics. This should be carefully considered during the monitoring of wound healing issues in these subset of patients. Also, adequate wound healing is very dependent of a good glycemic control. In your case, it might be appropriate to know whether your blood glucose control is effective. If it is, carrying out blood cultures, cultures on samples on the wound and anti biotic sensitivity tests could be advised. And thirdly, after removal for samples, placing patient on broad spectrum adapted injectable anti biotics could be of great help. Considering the very delicate nature of diabetics and possibility of cellulitis causing ostitis if non appropriately treated, I do not think its a good idea at this point in time to turn to herbal medicine. I suggest you meet your diabetologist for a proper follow up and care. thanks and best regards, Luchuo, MD.
