The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: Difficulty in defecation arises from the disharmony of the Zang-Fu organs, with Yin and Yang being biased towards excess or deficiency, and the San Jiao (Triple Burner) failing to function harmoniously, resulting in the binding of cold and heat pathogens.
