疮疡痈肿都是由热毒引起的，区分其阴阳属性是正确的。但又何必再分别虚实呢？不知道在阴阳之中，各自都包含虚证和实证。如果分辨不清楚，无论是用补法还是泻法，都是徒劳无功的。因此，必须辨别阴证中的虚与实、阳证中的虚与实，这才是妙法。
什么是阴证中的虚证？疮口平坦而不高起，且血色变得黯黑，这就是阴证中的虚证。什么是阴证中的实证？疮口起初平坦，后来变得坚实，血色红润，这就是阴证中的实证。虽然阴证都属于虚证范畴，但使用补法时也要分轻重程度。我现在设立一个方子，可以治疗这种情况：如果见到血色黯黑的，这是虚到了极点、寒到了极致的表现，方中加附子一钱、肉桂三钱，连续服用几剂，黑色必然转为红色。去掉附子后继续服用，自然疮口会长出肌肉而痊愈。如果起初就见到疮色红的，不必加附子和肉桂，连续照前方服用，必定完全痊愈。倘若不知道阴证的虚实而乱用附子和肉桂，恰恰足以导致失败。
什么是阳证中的虚证？疮口虽然高起，忽然颜色改变而不红，这是阳证将要转变为阴证的征兆，急宜使用金银花三两、当归身一两、附子一片（重二分）、生甘草三钱，煎汤饮用，颜色就会变红。这个方子名叫“转阳化毒丹”。此症是因为病患原本就不十分健旺，或者又加上房事过度或恼怒，一时之间发生变症，一刻也不能拖延。一见颜色改变就用此方，可以转危为安。
什么是阳证中的实证？疮口既高突巍然，而且颜色鲜红有光泽，这就是阳证中的实证。方用“泻阳祛毒丹”。此方治疗阳证的毒邪最佳，一剂就能排出毒邪，两剂毒邪就净，三剂就完全痊愈。如果是初起时高突的，一剂立刻消退，真是神方啊！这也是不可不知道的。

Carbuncles and sores are all caused by heat-toxin; distinguishing their Yin and Yang is correct. But why is it necessary to further distinguish between deficiency (Xu) and excess (Shi)? One must not fail to realize that within both Yin and Yang, there are respectively deficiency and excess conditions. If these are not clearly distinguished, whether using tonification or purgation methods will be in vain. Therefore, it is essential to discern deficiency within Yin and excess within Yin, as well as deficiency within Yang and excess within Yang; this is the subtle approach.
What constitutes deficiency within Yin? It is when the sore mouth is flat and not elevated, and the blood color becomes dark and blackish. This is deficiency within Yin. What constitutes excess within Yin? It is when the sore mouth is initially flat but later becomes solid, with ruddy red blood color. This is excess within Yin. Although Yin syndromes generally belong to deficiency categories, the application of tonification requires differentiation of severity. I now establish a formula that can treat such cases: if dark blackish blood color is observed, this indicates extreme deficiency and extreme cold. Add one qian of Fuzi (Aconiti Lateralis Radix Preparata) and three qian of Rougui (Cinnamomi Cortex) to the formula. After taking several doses continuously, the black color will inevitably turn red. Then remove Fuzi and continue taking the remaining prescription; naturally, flesh will grow over the sore, leading to recovery. If the sore color is red from the beginning, there is no need to add Fuzi and Rougui. Taking the original prescription continuously will lead to complete recovery. However, if one does not understand the deficiency and excess of Yin syndromes and indiscriminately uses Fuzi and Rougui, it will only lead to failure.
What constitutes deficiency within Yang? It is when the sore mouth is high and elevated, but suddenly changes color and loses its redness. This is a sign that a Yang syndrome is transforming into a Yin syndrome. Urgently use Sanliang (3 liang) of Jinyinhua (Lonicerae Japonicae Flos), Yiliang (1 liang) of Guishen (Angelicae Sinensis Radix), one pian (slice, weighing two fen) of Fuzi (Aconiti Lateralis Radix Preparata), and Sanqian (3 qian) of Sheng Gancao (Glycyrrhizae Radix et Rhizoma). Decoct and drink the soup; the color will immediately turn red. This formula is named Zhuan Yang Hua Du Dan (Yang-Transforming Toxin-Dissolving Pill). This condition arises because the patient was originally not very robust, or due to excessive sexual activity or anger, causing an sudden transformation of symptoms. Delay is not permissible. Upon observing the color change, use this formula immediately to turn danger into safety.
What constitutes excess within Yang? It is when the sore mouth is highly protruding and towering, with bright red and lustrous color. This is excess within Yang. Use the formula Xie Yang Qu Du Dan (Yang-Purging Toxin-Expelling Pill). This formula is best for treating toxins in Yang syndromes. One dose expels the toxin; two doses clear the toxin completely; three doses result in full recovery. If the sore is protruding at the initial stage, one dose causes immediate subsidence. It is truly a miraculous formula! This knowledge is also indispensable.
