  • Daikenchuto bioassay method and quality management method using same
    Patent number: 9121846
    Abstract: The invention intends to provide a bioassay method using a simple in-vitro test for Daikinchuto, and further to provide a more highly accurate method for quality control of Daikenchuto using the same.
