Core Tip

Core Tip: This study investigated the effects of a Japanese herbal medicine, namely rikkunshito (TJ-43), on patients who underwent pancreatic surgery. TJ-43 may promote oral food intake in patients in the early phase after pancreatic surgery because TJ-43 increases appetite by enhancing gastrointestinal and incretin hormone levels.
