After moxibustion, local skin appears redness and burning sensation, which is a normal phenomenon and does not need treatment. If local blisters appear due to excessive moxibustion for a long time, as long as you are careful not to scratch them, you can let them absorb naturally; If the blisters are large, you can use sterilized needles to break the blisters and drain water, or use injection needles to draw water and apply moxa powder to keep the wound dry.
