胆主筋。膀胱主骨是也。或中风。或伤寒。得病之日。便着床枕。非扶不起。筋骨为之疼痛。不能
动摇。乃形质之伤。经云。寒伤形。又云。寒则筋挛骨痛。此之谓也。

Li Gao stated: In diseases of internal injury, the Qi of the Heart and Lung has already failed externally. There must be lethargy and a desire to sleep, with the four limbs sinking and feeling heavy, unable to be held or moved. This is due to heat damaging the Yuan Qi (Original Qi). The Spleen governs the four limbs; once attacked by heat, there is no Qi to move. The Classics state: "Heat damages Qi," and also: "Heat causes bones to waste and tendons to relax." This refers to such cases. If it is an external contraction of Wind-Cold, the Qi of the Kidney and Liver has already failed internally. The Kidney governs the bones and corresponds to Cold; the Liver governs the tendons and corresponds to Wind. Since ancient times, diseases of the Kidney and Liver have been treated similarly because they maintain each other. Thus, the Classics state that the Gallbladder governs the tendons and the Bladder governs the bones. Whether contracting Wind-Stroke or Cold Damage, on the day of illness, one lies in bed, unable to rise without support, with pain in the sinews and bones, unable to move. This is an injury to the physical form. The Classics state: "Cold damages the form," and also: "Cold causes sinew spasm and bone pain." This refers to such cases.
[Gang] Zhang Zhongjing said: In Taiyang Wind-Strike syndrome, accompanied by diarrhea and vomiting/retching, only after the exterior syndrome is resolved can one attack the interior. If the patient sweats, with episodes occurring at specific times, headache, epigastric fullness and obstruction, hardness and distension pulling into the hypochondrium, dry retching, shortness of breath, sweating without aversion to cold, this indicates the exterior is resolved but the interior is not harmonized. Shizao Tang (Ten Jujube Decoction) should be administered.
[Mu] Zhu Gong said: Cool body with sweating, pain in both hypochondria, or dry retching, are symptoms of Shizao Tang syndrome. Generally, pain in the hypochondrium indicates the presence of fluid retention (Yin), requiring differentiation between exterior and interior. If there is dry retching, slight diarrhea, fever, and thirst, it is water-fluid in the exterior, treated with Xiao Qinglong Tang plus Yuanhua (Kansui Root). If the body is cool, the exterior syndrome has ceased, with dry retching and hypochondriac pain, it is water-fluid in the interior, treated with Shizao Tang. Shizao Tang is not comparable to Xiao Qinglong Tang; one must assess the patient's deficiency and excess before administering, and it should not be given recklessly.
Ke Qin said: When pathogenic water-fluid acts as a disease, here it moves outward to the skin and hair causing sweating, upward to the throat causing vomiting and retching, medially to the hypochondrium causing pulling pain, and downward to the intestines and stomach causing diarrhea. It is vast and uncontrollable; unless a harsh purgative for draining water-fluid is used to directly subdue it, the Middle Qi will collapse. This differs significantly from methods such as Wuling San (Five-Ingredient Powder with Poria), Xiao Qinglong Tang, and Xiexin Tang.
[Gang] Zhang Zhongjing said: In Taiyang disease, if ten days have passed, and the pulse is floating and fine with a desire to sleep, the exterior has been resolved. If chest fullness and hypochondriac pain appear, administer Xiaochaihu Tang (Minor Bupleurum Decoction). If the pulse is merely floating, administer Mahuang Tang (Ephedra Decoction).
[Mu] Lou Quanshan said: A faint, fine pulse with drowsiness is Shaoyin syndrome. A floating, fine pulse with a desire to sleep, without Shaoyin symptoms, even after ten days, still belongs to Taiyang. This refers to the state where the exterior is resolved but the condition is not yet completely clear. If chest fullness and drowsiness appear, it is also residual pathogen of Taiyang not yet dispersed. With added hypochondriac pain, it is a combined disease of Taiyang and Shaoyang. This is because the Shaoyang pulse is wiry and fine. Shaoyang serves as the pivot; when the pivot mechanism is unfavorable, the Qi of One Yang cannot ascend, resulting in chest fullness, hypochondriac pain, and drowsiness. Treat with Xiaochaihu Tang to harmonize. If the pulse is floating but not fine, it is floating and forceful; without chest and hypochondriac pain, it does not belong to Shaoyang. If floating but not large, it does not involve Yangming, remaining in Taiyang. Taiyang serves as the opening; use Mahuang Tang to open it. However, this differs from using Mahuang Tang to induce sweating in the initial stage of Taiyang disease. The dosage should be reduced and administered in small amounts.
Shen Jin'ao commented: This discusses the correlation between Taiyang and Shaoyang pulses and symptoms. Hypochondriac pain is originally a Shaoyang symptom.
[Gang] Zhang Zhongjing said: After Cold Damage was treated with emesis and purgation, followed by repeated sweating, leading to vexatious restlessness, with a very faint pulse. By the eighth or ninth day, epigastric hardness and obstruction, hypochondriac pain, Qi rushing up to the throat, vertigo and dizziness, and twitching/trembling of the meridians, if prolonged, will develop into Wei Syndrome (Flaccidity Syndrome).
[Mu] Shen Jin'ao commented: In this clause, hypochondriac pain accompanied by twitching/trembling of the meridians belongs to deficient Qi. The Qi rushing to the throat and vertigo/dizziness are manifestations of the aforementioned vexatious restlessness.
