The story
- Japanese · derived from艾“mugwort”
- English todaymoxa
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.
