论曰∶贼风偏枯者，是体偏虚受风，风客于半身也。人有劳伤血气，半身偏虚者，风乘
虚入，客于半体，名为偏风也。其风邪入深，真气去，邪气留，发为偏枯。此由血气衰损，
为风所客，令血气不相周荣于肌，故令偏枯也。
论曰∶夫偏枯者，其状半身不遂，肌肉枯瘦，骨间疼痛，神智如常，名曰偏枯。仆原疾
之由，皆由阴阳偏亏，脏腑怯弱，经络空虚，血气不足，当风冲坐，风邪乘虚而入，疾从斯
作。《内经》云∶汗出偏沮，使人偏枯。详其义理，如树木或有一边津液不荫注而先枯槁，
然后被风所害。人之身体，或有一边血气不能荣养而先枯槁，然后被风所苦，其理显然。王

It is stated: "Zei wind" (thieving wind) causing hemiplegia occurs when one side of the body is deficient and susceptible to wind pathogen, which lodges in half of the body. If a person suffers from labor-induced injury to blood and qi, resulting in deficiency on one side, the wind pathogen enters through this deficiency and lodges in half of the body; this is called "Pian feng" (hemiplegic wind). If the wind pathogen penetrates deeply, depleting the true qi while the evil qi remains, it develops into "Pian ku" (hemiplegic emaciation). This arises from the depletion of blood and qi, invaded by wind pathogen, preventing blood and qi from circulating and nourishing the muscles and skin, thus causing hemiplegic emaciation.
It is stated: The manifestation of Pian ku includes hemiplegia, emaciated muscles, pain in the bones and joints, while mental clarity remains intact; this condition is named Pian ku. Investigating its etiology, it stems from an imbalance and deficiency of Yin and Yang, weakness of the Zang-Fu organs, emptiness of the meridians, and insufficiency of blood and qi. Sitting exposed to drafts allows wind pathogen to enter via deficiency, initiating the disease. The *Neijing* states: "Sweating on only one side leads to Pian ku." Analyzing its principle, it is like a tree where, if fluids fail to irrigate one side, that side dries up first and then suffers wind damage. Similarly, if blood and qi fail to nourish one side of the human body, that side becomes dry and vulnerable to wind pathogen; the logic is clear. Wang Ziheng said: "Boats travel on water, humans exist in wind. Water can float or capsize a boat; wind can nourish or harm the body." This implies that just as a leaking boat lets water in, a body with "leaks" allows wind injury. As the ancients said: "To treat wind, first treat the blood; when blood flows, wind extinguishes itself." Treatment should first nourish the blood, then dispel wind, ensuring recovery. Suitable formulas include Da Ba Feng Tang (Great Eight-Wind Decoction), Zeng Sun Yinyu Jiu (Modified Yinyu Wine), and Xuduan Tang (Dipsacus Decoction).
