OIs are significant cause of morbidity and mortality among AIDS patients. Professor LI Xiuhui believes that the pathogenesis of OIs lies in turbid toxins entering the blood, infecting the Sanjiao, damaging the nutrient Qi and defensive Qi, consuming Qi and essence, and impairing the primordial Qi. As a result, the five organs are weakened, pathogenic toxins overflow, leading to the occurrence of some related opportunistic infectious diseases in various systems throughout the body. Therefore, in treatment, the “penetrating and supporting method” and the “tonifying and supporting method” are used to consolidate and support the healthy Qi, allowing the pathogenic toxins to be expelled smoothly,so that the opportunistic infectious diseases can be cured or controlled.展开更多
