It is normal for the local skin to appear slightly red and burning after moxibustion. Some people have red spots on the abdomen after moxibustion, this is due to the normal phenomenon that occurs during the process of moxibustion, which indicates a so-called transmoxibustion theory, this transmoxibustion theory is the process of moxibustion requires a longer moxibustion time, and the amount of moxibustion needs to be larger, the appearance of red spots on some difficult diseases better. When the red spot appears, must stop further moxibustion to prevent the appearance of burns, so in the process of operation must pay attention to the time and moxibustion heat.
