The following is a brief summary of moxa production process, traditionally used in Yamasho, the authentic Moxa manufacture in Japan.
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.
Dried Mugwort Leaves
In the beginning of winter (dry season in Japan), the sun-dried leaves are placed in heated drying Compartments in order to complete the drying process.

The dried leaves are grinded in the stone mills (rough and fine grinding mills).

The ground leaves undergo sifting process in order to remove presence of impurities (mesophyll, stems etc.).
Sifting in the machinery called Nagadoshi
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.

The moxa products undergo quality inspection procedures prior to packaging.
