Patchouli Zhengqi Shui has the efficacy of relieving the surface and resolving dampness (relieving the externally-induced evils and getting rid of the dampness in the body), regulating qi and zhong (regulating the qi of the spleen and stomach to make the functions of the spleen and stomach smooth), and it is mainly used to treat the symptoms of vomiting, diarrhea, fever, head and body pains caused by the externally-induced wind and cold mixed with the dampness within the body.
