There are several different formulas by the name of Jian Pi Wan (‘Strengthen the Spleen Pill’), all of which have the same clinical actions. It was originally recorded in texts on Chinese medicine in 17th century China. Although the original formula contained thirteen ingredients, modern formulations typically contain only six, and this formula is strongly focused on its specific treatment principles, allowing a broad range of clinical applications. Furthermore, because of the economy of ingredients, it is compatible with a wide variety of other formulas in the treatment of patients with multiple TCM syndrome-patterns.
