ABSTRACT
The authors investigated the activity of Kikyo-to on the intestinal hormones, cholecystokinin (CCK) and secretin, released in healthy humans. The clinical efficacy of Kikyo-to on the abdominal symptoms associated with chronic pancreatitis was also investigated. In healthy volunteers, Kikyo-to (5g) significantly increased plasma CCK and secretin concentrations 30 minutes after treatment. In chronic pancreatitis patients, abdominal pain, abdominal tenderness, nausea and diarrhea were decreased by treatment with Kikyo-to (7.5g/day; divided into three doses). In conclusion, Kikyo-to improved the complaints of chronic pancreatitis, especially abdominal pain. The presumed mechanism was that Kikyo-to stimulated pancreatic exocrine secretion by the release of intestinal hormones, CCK and secretin.
