As with any medical treatment, moxibustion can have adverse effects, although they are usually
mild and rare. The most common adverse effect is an allergic reaction, while other rare adverse
effects include xerophthalmia, xeroderma, hyperpigmented macules, ptosis, and eversion of the
eyelids. It is important to exercise caution when using moxibustion, and to stop using it if any
adverse effects occur. If any adverse effects persist, it is recommended to seek help from
medical professionals. To minimize the risk of adverse effects, it is suggested to start with a
short duration of moxibustion (e.g., 5 minutes) for the first time, and gradually increase the
duration to allow the body to adjust to the effects.
