Moxa Manufacturing Process in Japan

The following is a brief summary of moxa production process, traditionally used in Yamasho, the authentic Moxa manufacture in Japan.

HARVESTING

Mugwort (Artemisia vulgaris) leaves are harvested from late spring to summer in Japan.  The hand-picked leaves are placed under the sun for drying.

Note: Chinese mugwort (Artemisia argyi Levl. et Vant.) is used internally in Chinese medicine and Japanese Kampo medicine.

PURIFYING

In order to produce a higher grade moxa (refined, smooth texture with golden color), further purifying process is required using the machinery called Tomi. The higher quality moxa is desired, particularly when conducting direct moxibustion.
