Herbal Baths and Foot Soaks zhōng yào yào yù yǔ zú yù · 中药药浴与足浴

Soaking in water infused with herbs is an old external method, recorded in classical texts on external treatment. Foot soaking in particular became a routine household practice rather than a clinical procedure.

The usual classical reasoning is that warmth opens the pores and moves the surface, and that the feet are where several channels begin or end. What the practice is not is a way to treat internal disease through the skin.

Real risks are simple and worth stating plainly: water hot enough to burn, especially where sensation in the feet is reduced; skin that is broken, infected or freshly injured; and allergic reaction to a herb you have not used before. Diabetes with reduced foot sensation is the clearest case where this is not a casual activity.
