White flesh inside a wound is usually rotting flesh. If there is an open wound on the body, there will be granulation tissue formation during the wound healing process. Normally, the granulation tissue is bright red in color, and when touched, it is fragile and bleeds easily, indicating that it is fresh tissue, which suggests that the wound is healing well. If the tissue is white, there is no blood supply to the tissue, suggesting that it is inactive tissue, commonly known as rotten flesh, which is not conducive to wound healing. The presence of rotting flesh in the wound is detrimental to wound healing, so it needs to be removed promptly. After the rotting flesh is removed, fresh tissue will grow inside the wound, thus promoting wound healing.
