Possible reactions to moxibustion include soreness, numbness, pain, swelling, itchiness, dizziness and cold.
A simple analogy can help clarify this: when a pipe is blocked it will face some resistance, or expand when we want to clear it. Body vessels and channels are similar. When Yang chi encounters Yin negative chi there will be a struggle that might manifest in some of the sensations described above. If we have toxins or an area of inflammation, we will likely feel discomfort. Itchiness is typically due to heavy moisture and heat; it’s a reaction to the release of damp heat. Women with a gynecological complaint may feel soreness in the abdomen. A gastritis patient will often have stomach pain. A person with damp cold in the intestines will feel the abdomen rumbling when the therapy is done on the navel. All these are positive responses showing that Yang chi has entered the body. Continue the moxibustion and these reactions will subside and the improvements to your body will start to become much clearer.
