五脏更相平也，一脏不平，以所胜平之。故曰，安谷则昌，绝谷则亡，水去则荣散，谷
清则卫荣，荣散则亡，神无所居。仲景云，水入于经，其血乃成，谷入于胃，脉道乃行。故
血不可不养，卫不可不温，血温卫和，荣卫将行，常有天年。又曰，人之一身，外为阳、内
为阴。背为阳，腹为阴。腑为阳，脏为阴。阳中之阳，心也。阳中之阴，肺也。阴中之阴，
肾也。阴中之阳，肝也。阴中之至阴，脾也。

火，条芩泻大肠火，黄柏泻膀胱火，滑石泻六经火，栀子泻屈曲火。

火也。余治例此。

五脏之间相互保持平衡，如果某一脏失去平衡，就用它所克制的脏来调节它。所以说，能够进食则生命力旺盛，不能进食则生命力衰竭；津液流失则营血散失，谷物消化正常则卫气和营血调和，营血散失则会死亡，神志也就无处安身。张仲景说，水进入经脉，血液才能生成；谷物进入胃中，脉道才能通畅运行。所以血液不可不滋养，卫气不可不温煦，血液温暖、卫气调和，营卫之气就能正常运行，人便能享有自然的寿命。又说，人的全身，外部属阳，内部属阴；背部属阳，腹部属阴；六腑属阳，五脏属阴。阳中之阳是心，阳中之阴是肺，阴中之阴是肾，阴中之阳是肝，阴中之至阴是脾。
黄连能清泻心火，黄芩（枯芩）能清泻肺火，白芍能清泻肝火，柴胡配黄连能清泻肝胆之火，木通能清泻小肠之火，知母能清泻肾火，黄芩（条芩）能清泻大肠之火，黄柏能清泻膀胱之火，滑石能清泻六经之火，栀子能清泻曲折难解之火。
寒证用热药治疗，热证用寒药治疗。病情轻微的采用逆其病性治疗的正治法，病情严重的采用顺从病性治疗的反治法。坚积者予以消削，外邪入侵者予以祛除。劳损者予以温补，郁结者予以疏散，停滞者予以行导，干燥者予以滋润。虚损者予以补益，惊悸者予以平定，安逸过度者予以运动疏导，气机上逆者予以降逆。逆病势而治称为正治，顺病势而治称为反治。

假如风邪侵袭体内，就是肝木失常，火随之炽盛，治疗用辛凉药物，这是利用辛金克制肝木，利用凉水浇灭炎火。其余的治疗原则都依此类推。

The Five Viscera (Zang organs) maintain mutual balance. If one viscera becomes unbalanced, it is regulated by the organ that controls it. Thus it is said: Ability to digest food leads to prosperity; inability to digest food leads to demise. Loss of fluids leads to dispersion of Ying Blood (Nutritive Blood); proper digestion of grain harmonizes Wei Qi (Defensive Qi) and Ying Blood. Dispersion of Ying Blood leads to death, and Shen (Spirit) has no place to reside. Zhang Zhongjing said: When water enters the meridians, blood is formed; when grain enters the stomach, the vessel pathways begin to flow. Therefore, blood must not fail to be nourished, and Wei Qi must not fail to be warmed. When blood is warm and Wei Qi is harmonious, Ying and Wei Qi will circulate properly, allowing one to enjoy a natural lifespan. It is also said: In the human body, the exterior is Yang and the interior is Yin; the back is Yang and the abdomen is Yin; the Fu Organs (Hollow Organs) are Yang and the Zang Organs (Solid Organs) are Yin. The Yang within Yang is the Heart; the Yin within Yang is the Lung; the Yin within Yin is the Kidney; the Yang within Yin is the Liver; the Ultimate Yin within Yin is the Spleen.
Coptis Rhizoma (Huanglian) drains Heart Fire; dried Scutellaria Root (Kuhuangqin) drains Lung Fire; White Peony Root (Baishao) drains Liver Fire; Bupleurum Root (Chaihu) combined with Coptis Rhizoma drains Liver-Gallbladder Fire; Akebia Caulis (Mutong) drains Small Intestine Fire; Anemarrhena Rhizoma (Zhimu) drains Kidney Fire; Scutellaria Root (Tiaohuangqin) drains Large Intestine Fire; Phellodendron Bark (Huangbai) drains Bladder Fire; Talcum (Huashi) drains Fire in all six meridians; Gardenia Fruit (Zhizi) drains Fire in convoluted pathways.
Cold conditions are treated with Heat methods; Heat conditions are treated with Cold methods. Mild cases are treated by opposing the pathogenic factor (Direct Treatment); severe cases are treated by following the pathogenic factor (Reverse Treatment). Indurations are reduced; exogenous pathogens are eliminated. Debility is warmed; stagnation is dispersed; retention is moved; dryness is moistened. Deficiency is supplemented; palpitations are calmed; lethargy is activated; upward rebellion is directed downward. Opposing the disease nature is called Direct Treatment (Zheng Zhi); following the disease nature is called Reverse Treatment (Fan Zhi).
The Liver corresponds to Spring Wood and Sour flavor, governing the principle of generation. If this function is失常 (abnormal), disease occurs.
When Wind invades internally, treat with Pungent-Cold herbs, assist with Sweet-Pungent herbs, use Sweet herbs to relax/tension, and use Pungent herbs to disperse.
The Heart corresponds to Summer Fire and Bitter flavor, governing the principle of growth. If this function is abnormal, disease occurs.
When Heat invades internally, treat with Salty-Cold herbs, assist with Sweet-Bitter herbs, use Salty-Sweet herbs to astringe/collect, and use Bitter herbs to vent/disperse.
The Spleen corresponds to Central Earth and Sweet flavor, governing the principle of transformation. If this function is abnormal, disease occurs.
When Dampness invades internally, treat with Acid-Hot herbs, assist with Salty-Cold herbs, use Bitter herbs to dry dampness, and use Acrid/Light herbs to drain/diurese.
The Lung corresponds to Autumn Metal and Pungent flavor, governing the principle of gathering/restraining. If this function is abnormal, disease occurs.
When Dryness invades internally, treat with Bitter-Warm herbs, assist with Sweet-Pungent herbs, use Pungent herbs to moisten, and use Bitter herbs to purge/downbear.
The Kidney corresponds to Winter Water and Salty flavor, governing the principle of storage. If this function is abnormal, disease occurs.
When Cold invades internally, treat with Sweet-Hot herbs, assist with Bitter-Pungent herbs, use Pungent herbs to vent/dispatch, and use Bitter herbs to consolidate/firm.
For example, if Wind invades internally, it indicates Liver Wood dysfunction, causing Fire to blaze subsequently. Treatment uses Pungent-Cold herbs: this utilizes Pungent Metal to control Liver Wood, and Cool Water to extinguish blazing Fire. The remaining treatment examples follow this logic.
