Mugwort. It's a weed that grows wild in many parts of the world. Here in Korea, people use mugwort for many different reasons and in many different ways. The first time I was exposed to mugwort was in a sauna where they had a mugwort hot tub. There was a sign on the wall that tried to explain the medical benefits of soaking in this tub, but of couse the translation was really terrible and I couldn't get much out of it. The only thing I learned from that tub was that mugwort is good for "gynelogical diseases"...Sometimes the translations aren't the best, but the idea of soaking in a hot tub that people with gynelogical disorders seek out was especially troubling. I jumped in anyway.
