Liu Wei Di Huang Wan was first published in Qian Yi’s “The Straight Guide to Pediatric Medicine”, and was composed on the basis of the Kidney Qi Pill in the “Jin Kui Yao”, minus the cinnamon branch and the sophora. In the original text, it was used to treat the deficiency of liver and kidney yin in children, but nowadays it is mostly used to treat the deficiency of liver and kidney yin. The medicine is a very good Chinese medicine for nourishing Yin, with three tonics and three diarrhea inside, and rarely has side effects when taken normally. However, in Chinese medicine, kidney deficiency often includes kidney yin deficiency, kidney yang deficiency, kidney essence deficiency, kidney qi deficiency, etc. As the saying goes, there is no tonic for the deficiency, after all, it is a tonic, long-term use, for Yang deficiency physique, may appear greasy, phlegm and damp, leading to disease. The most important thing is to make sure that you have a good understanding of the liver and kidney yin deficiency, so can you take it for a long time? In fact, it may not be. Because the overall dosage of “three diarrhea” is less than that of “three tonic”, after all, it is a tonic formula, so people with poor spleen and stomach function should not take it continuously for a long period of time, otherwise it will easily hinder the normal digestive function. Even healthy people, long-term use may also appear full abdomen, loose stools, loss of appetite and other symptoms, so taking the drug, the right amount at the right time is the best choice. If taken for a long time, it is best to perform under medical advice, otherwise it is likely to be counterproductive.
