Does plant ash have an effect on people's wounds? The wound is large, and the scarring wound is 5cm long, 3cm wide and 0.5cm deep.

It depends on the structure of the skin. Human skin is divided into multiple layers. The cells at the bottom layer of epidermis are called mucus layer, which has strong vitality and can grow and reproduce continuously. The superficial wound of epidermal injury is healed by mucus layer, and the nerve is not stimulated. This wound usually doesn't feel itchy when it heals.

However, the wound is large, and the wound deep into the dermis often itches when it heals quickly. This is because the healing of deep wounds is made up of a new tissue called connective tissue. New blood vessels and nerves will grow connective tissue. These new blood vessels and nerves are particularly dense. Everyone is crowded together, and the new nerves are easily stimulated. Because the nerves are very sensitive, they will feel itchy.

The regenerative capacity of human tissues is also different. The regeneration ability of nerve tissue is low, which appears in the late stage of wound healing, usually when the nerve grows well and the wound grows well. At this time, new nerve endings and blood vessels have grown into connective tissue, and local perception has gradually recovered, so the wound will itch at this time. People have the urge to scratch. A word of advice: Rub a little moisturizing lotion around the wound to avoid itching.

In the process of skin wound healing, platelets will promote wound healing, and the wound will gradually turn from wet to dry. At this time, epidermal cells will stimulate itchy nerve receptors, so people will feel itchy skin.

Itchy skin is a normal phenomenon, and the wound will heal. Don't scratch with your hands, lest the wound rupture again. Rub a little moisturizing lotion around the wound to avoid dryness and itching. Don't scratch, it will leave a scar! Remember! ! ! ! !
