コタロー大建中湯エキス細粒
Daikenchuto (Kampo for bowel function)
Daikenchuto (Kampo extract)
Daikenchuto (ginger, ginseng, Japanese pepper and maltose) is the Kampo formula most studied in modern clinical trials; Japanese surgeons prescribe it routinely to restore bowel movement after abdominal surgery and for bloating. It is a good example of how Kampo is integrated into Japanese hospital medicine.
