The key lies in the heart, liver, and spleen. The "Plain Questions: On the Generation of the Five Zang Organs" states: "All blood belongs to the heart." This clarifies the subordinate relationship between the heart and the body's blood. Tang inherited this view, believing that "the heart is the sovereign fire, which generates blood... When the fire rises, the blood rises; when the fire falls, the blood falls. Knowing that blood is generated by fire and that fire resides in the heart, we understand that draining the heart means draining the fire, and draining the fire means stopping the bleeding." He used this theory to guide clinical treatment, thereby elucidating the mechanism by which Dahuang Huanglian Xie Xin Tang treats blood disorders. The liver governs the storage of blood, so it is also an organ crucial for the overall management of blood disorders. Tang believed: "The reason blood circulates throughout the body is due to the Chong, Ren, and Dai meridians, which regulate its flow. The Blood Sea is located in the uterus, serving as the place where blood is transported and stored. The liver controls the Blood Sea, and the Chong, Ren, and Dai meridians are also under the liver's control. Therefore, when tonifying blood, the primary focus should always be on tonifying the liver." This indicates that the normal circulation of blood originates from the Blood Sea in the uterus and is regulated throughout the body by the Chong, Ren, and Dai meridians, a process overseen by the liver. Thus, treating blood disorders requires mastering the important principle of regulating the liver. Formulas such as Siwu Tang and Xiaoyao San have become important prescriptions for treating blood disorders precisely because they are based on this principle. The spleen is the foundation of postnatal life and governs the transformation and transportation of food essence. Based on the "Inner Canon," which states that the Jiao receives qi and extracts juice, transforming it into red blood, Tang particularly emphasized the significance of the spleen and stomach in treating blood disorders, believing that "the principle of blood production lies in the spleen and stomach." Gui Pi Tang, Renshen Yangrong Tang, Buzhong Yiqi Tang, and Zhigancao Tang are widely used to treat blood disorders precisely because they are based on regulating the spleen and stomach. In addition, in the late stages of blood disorders, tonification is appropriate, and tonifying the kidney and lung are both quite necessary.
