Is it beneficial for moxibustion smoke to enter the uterus?
Under normal circumstances, there is no clear benefit to allowing moxibustion smoke to enter the uterus; on the contrary, it may pose health risks, and deliberate exposure is not recommended. If you have concerns, it is advisable to consult a healthcare professional in advance. The detailed explanation is as follows:

The primary effect of moxibustion lies in regulating the body through thermal stimulation of acupoints. Its active components work via skin absorption or meridian conduction, rather than through direct entry of smoke into the uterus. Moxibustion smoke mainly consists of particulate matter and volatile oils produced by burning mugwort, which do not directly nourish the uterus or treat gynecological conditions. In fact, entering the uterus, such smoke may disrupt the internal environment's stability.
If large amounts of moxibustion smoke enter the body, discomfort may occur. Particles in the smoke can irritate the respiratory mucosa, causing coughing or chest tightness, and sensitive individuals may even experience allergic reactions. Regarding the uterus, foreign smoke irritation may disturb the local microbial balance and potentially worsen pelvic congestion. Women with gynecological inflammation, in particular, may experience aggravated symptoms—such situations must be strictly avoided.
During moxibustion, ensure adequate ventilation to prevent smoke accumulation, and never deliberately expose private areas to the smoke. Gynecological issues should be managed under the guidance of qualified medical professionals, using standardized acupoint moxibustion techniques. If respiratory or abdominal discomfort occurs after moxibustion, discontinue use immediately and seek medical advice.
