Does the Burning of Moxa ( <i>Artemisia vulgaris</i> ) in traditional Chinese medicine constitute a health hazard?

There are no immediate concerns arising from the continued use of moxa as a therapeutic modality in traditional Chinese medicine. Further testing may be required to establish whether current recommendations for ventilation and cleansing of treatment room surfaces may need to be revised. Stronger recommendations may also be necessary on the inadvisability of using moxa on broken skin.
