经言诸痿皆起于肺。说者谓肺气空虚，金不伐木，肝火郁结，大筋短缩，小筋弛长，故成痿症
，此特可为筋痿言之耳。至于脉痿、肉痿、骨痿，岂得谓之金不伐火、金不伐土、金不伐水乎？是
必不然矣。解经者不必过事高深，但求谛当。经又曰∶治痿独取阳明。只此一节，便可知肺胃相关，
诸痿起于肺，治痿重阳明之故。盖胃为水谷之腑，一身之精神气血，从此而生。其糟粕则下归小肠
；其精华则上输于肺，肺受精气，然后泽及诸脏。兹以所求不得，躁急热中，肺受熏蒸，叶焦成痿
，不能散精于他脏，故痿起于肺也。其独取阳明者，因胃为五脏六腑之海，所以滋养一身，又主润
宗筋，宗筋主束骨而利关节也。从此悟彻，则五脏之痿，可以次第区别矣。
经曰∶肺热叶焦，则皮毛虚弱急薄，着则生痿 也。其下又曰∶所求不得，则发肺鸣，鸣则肺
热叶焦。则此症全因肺阴耗散，肺气空虚所致。盖肺为主气之脏，肺伤则元气薄弱而不能下行，故
足膝无力而不能任地，是肺痿即气痿也，玉华煎主之。

古籍记载说，各种痿证都起源于肺。解释的人认为，这是因为肺气空虚，金（肺）不能克制木（肝），导致肝火郁结，大筋短缩，小筋松弛延长，从而形成痿症。但这仅适用于筋痿而言。至于脉痿、肉痿、骨痿，怎么能说是金不克火、金不克土、金不克水呢？这显然是不对的。解释经文的人不必刻意追求高深，只求恰当准确。经文又说：“治疗痿证，唯独取法于阳明经。”仅这一条，就可以知道肺与胃的关系，以及诸痿起于肺、治疗痿证重视阳明的原因。因为胃是水谷之腑，一身的精神气血，由此而生。其糟粕则向下归入小肠；其精华则向上输送到肺，肺接受精气后，然后滋润各脏腑。现在因为所求不得（指欲望未遂或生理需求受阻），导致躁急热中，肺受到熏蒸，叶焦而成痿，不能将精气散布到其他脏腑，所以痿证起于肺。之所以唯独取法阳明，是因为胃是五脏六腑的海，用来滋养全身，又主管润泽宗筋，宗筋主束骨而利关节。从此领悟透彻，那么五脏的痿证，就可以依次区别了。
经文说：“肺热叶焦，则皮毛虚弱急薄，着则生痿躄也。”其下又说：“所求不得，则发肺鸣，鸣则肺热叶焦。”那么这个病症完全是由于肺阴耗散，肺气空虚所致。因为肺是主气的脏，肺受伤则元气薄弱而不能下行，所以足膝无力而不能站立承重，这是肺痿即气痿，用玉华煎主治。

The classics state that all flaccidity syndromes (Wei Syndrome) originate from the Lung. Commentators explain that this is due to emptiness of Lung Qi, where Metal (Lung) fails to control Wood (Liver), leading to stagnation of Liver Fire, shortening of large tendons, and laxity/elongation of small tendons, thus forming a tendon flaccidity syndrome. However, this applies only to tendon flaccidity. What about pulse flaccidity, flesh flaccidity, and bone flaccidity? How can one say that Metal fails to control Fire, Earth, or Water in these cases? This is certainly incorrect. Those interpreting the classics need not seek excessive profundity but should aim for appropriateness. The classics also state: "In treating flaccidity, exclusively select the Yangming." From this single sentence, one can understand the relationship between the Lung and Stomach, and the reasons why flaccidity originates in the Lung and treatment emphasizes the Yangming. The Stomach is the palace of water and grain; the spirit, qi, blood, and fluids of the entire body are generated from it. Its dregs descend to the Small Intestine; its essence ascends to the Lung. After the Lung receives the essence and qi, it then moistens the other zang organs. Now, due to unfulfilled desires causing restlessness and internal heat, the Lung is steamed, leaves become scorched and dry, resulting in flaccidity. It cannot scatter essence to other organs, hence flaccidity originates in the Lung. The reason for exclusively selecting Yangming is that the Stomach is the sea of the five zang and six fu organs, nourishing the whole body, and it governs the moistening of the Zongjin (Major Tendons). The Zongjin binds the bones and facilitates joint movement. Once thoroughly comprehended, the flaccidity of the five zang organs can be distinguished sequentially.
The classics state: "When Lung Heat scorches the leaves, the skin and hair become weak, thin, and tight; if it lingers, Feibi (flaccidity with inability to walk) arises." It further states: "Unfulfilled desires cause Lung Ming (lung sounds/cough); Ming leads to Lung Heat scorching the leaves." Thus, this condition is entirely caused by the consumption of Lung Yin and emptiness of Lung Qi. Since the Lung is the organ governing Qi, injury to the Lung results in weak Yuan Qi that cannot descend, leading to weakness in the feet and knees unable to bear weight. This is Lung Flaccidity, which is essentially Qi Flaccidity, treated with Yuhua Decoction.

The classics state: "Heart Qi Heat causes lower vessels to reverse upward; when they reverse upward, lower vessels become deficient; deficiency generates Pulse Flaccidity. The pivot breaks and cannot be lifted; the shins are relaxed and cannot bear the ground." All vessels converge on the Heart. When Heart Yang rises excessively, the vessels below also reverse upward. The more excess above, the more deficiency below, thus generating Pulse Flaccidity. At the joints, it is like a broken pivot that cannot be lifted. The relaxation of the shins means the vessels are blocked and lax. Treated with Tiaoying Tongmai Decoction.

The classics state: "Liver Qi Heat causes Gallbladder bile to leak, resulting in a bitter taste; the fascia becomes dry. Dry fascia leads to tendon tension and contraction, manifesting as Tendon Flaccidity." The Liver and Gallbladder are connected; Liver Heat causes Gallbladder Heat, boiling the bile internally, hence the bitter taste. Blood is seized by fire and cannot nourish the tendons, leading to tension and contraction, thus becoming Tendon Flaccidity. Treated with Shuimu Huazi Decoction.

The classics state: "Spleen Qi Heat causes the Stomach to become dry and thirsty; muscles become insensible, manifesting as Flesh Flaccidity." The Spleen and Stomach both belong to Earth, differing in dryness and dampness. If damp Earth is hot, dry Earth becomes even hotter, hence the Stomach is dry and thirsty. Heat stagnating internally consumes Spleen Yin, so the muscles become insensible and flaccid. Treated with Kunshun Decoction.

The classics state: "Kidney Qi Heat causes the waist and spine to be immobile; bones become withered and marrow decreases, manifesting as Bone Flaccidity." It also states: "Traveling far and working to exhaustion, encountering great heat and thirst, thirst causes Yang Qi to attack internally; internal attack allows heat to reside in the Kidney. The Kidney is the Water Organ; now Water cannot overcome Fire, so bones become withered and marrow empty, hence the feet cannot support the body, manifesting as Bone Flaccidity." The waist is the mansion of the Kidney, and the spine is penetrated by the Kidney; Kidney injury causes immobility of the waist and spine. Far travel and exhaustion injure the bones. Encountering great heat and thirst, whether external pathogenic heat or internal accumulated heat, both consume Yin and reduce marrow, so bones become withered and flaccid.
