It is generally best to take a medicated bath once every 2~3 days, which can play a very good role in conditioning the body. However, if you soak your feet for a short time, it will cause the loss of nutrients and affect the curative effect of Artemisia argyi. If the body has asthenic cold, a medicated bath once a day can relieve it for 7~ 10 days. The medicated bath has the effects of warming meridians, dispelling cold, promoting blood circulation, removing blood stasis, warming kidney and warming uterus, and has a good therapeutic effect on abdominal cold pain caused by deficiency cold.
