From Japanese 艾 (mogusa, “mugwort”). The u is not strongly pronounced in Japanese, leading to its disappearance and the devoicing of the plosive. First used by Hermann Buschoff, a Dutch minister in Batavia, who wrote the first book about this remedy in 1674.
- Dried leaves of an Asian species of mugwort, Artemisia argyi as used in moxibustion.
- Any other plant used in moxibustion.
