Colonic Vascular Conductance Increased by Daikenchuto via Calcitonin Gene-Related Peptide and Receptor-Activity Modifying Protein 1

Background Daikencyuto (DKT) is a traditional Japanese medicine (Kampo) and is a mixture of extract powders from dried Japanese pepper, processed ginger, ginseng radix, and maltose powder and has been used as the treatment of paralytic ileus. DKT may increase gastrointestinal motility by an up-regulation of the calcitonin gene-related peptide (CGRP). CGRP is also the most powerful vasoactive substance.
