Generally speaking, pregnant women can smell moxibustion, and there is no harm in smelling moxibustion in small amounts, as it can play a role in calming the fetus. However, it is important not to smell a lot of moxibustion to avoid smoke irritation. Some pregnant women are allergic and may have allergies after smelling moxibustion, so they are advised not to smell moxibustion. In addition, pregnant women in early pregnancy have severe early pregnancy reactions, so if they smell moxibustion, they should not smell moxibustion if they experience nausea or vomiting. If the smell of moxibustion is heavy, it may stimulate the respiratory tract and cause coughing and breathing difficulties. There are not many opportunities for pregnant women to apply moxibustion, because moxibustion works by stimulating certain acupuncture points in the body with moxa heat, and some of them may move the fetal energy, especially in early and late pregnancy. If a pregnant woman needs moxibustion treatment during pregnancy, it is recommended to go to a regular hospital and undergo a forensic analysis by a Chinese medicine practitioner to determine whether moxibustion can be performed.
