In general, Wu Ling San can be used by people with phlegm-damp body, but it should meet the indications and follow the doctor’s instructions. Wu Ling San has the effect of inducing dampness and promoting water circulation (the method of inducing dampness and dispelling dampness), warming yang and transforming qi (warming yang qi), and is effective in treating edema, bloating, vomiting, diarrhea, and dysuria triggered by water-dampness (water-dampness staying in the body) and yang non-transformation of qi (the body’s qi is blocked). People with phlegm-dampness constitutions who have these symptoms are also eligible for medication under the guidance of a doctor. In addition, the formation of phlegm-dampness is also related to the internal stoppage of water-dampness, because the internal stoppage of water-dampness implies that there is an abnormality in the distribution and excretion of fluid in the patient’s body, and the long-time stoppage of water fluid in the body may form phlegm-dampness, and from this point of view, people with phlegm-dampness taking Wu Ling San is helpful for the improvement of their condition. Although the side effects of Wu Ling San are not very clear, but the patient should not use the drug privately, if you need to take this drug, you must strictly follow the doctor’s instructions.
