Diarrhea is a watery stool occurring more than three times in one day followed by changing in feces form from solid to liquid. In general, diarrhea is a light disease, but it can be more serious especially to infant. Because of that, this research was done to know whether the infusion of salak gading (Salacca edulis Reinw.varr) fruit, which contains tannin as an active substance, with and without its epidermis has an obstipancia effect.
