> You Zaijing (fl. 1749), styled Zaijing, styled Zhuowu, alias Feiheshanren, was a physician from Changzhou (now Wuxian, Jiangsu) during the Qing Dynasty. This book compiles and annotates five of You Zaijing's medical works, including Shanghan Guizhu Ji (8 volumes), Jin Gui Yao Lue Xin Dian (3 volumes), Jin Gui Yi (8 volumes), Yixue Du Shu Ji (3 volumes with Xu Ji as an appendix), and Jing Xiang Lou Yi An (2 volumes). Among them, Shanghan Guizhu Ji provides line-by-line annotations and elaborations on Zhang Zhongjing's Shanghan Lun, and rearranges and categorizes some of the original content of Shanghan Lun. Jin Gui Yao Lue Xin Dian offers line-by-line annotations and elaborations on Zhang Zhongjing's Jin Gui Yao Lue. Both Guizhu Ji and Xin Dian provide extensive insights and guidance on Zhang Zhongjing's original works, serving as important reference materials for later scholars studying Shanghan Lun and Jin Gui Yao Lue. Jin Gui Yi primarily focuses on the etiology, diagnosis, treatment, and prescriptions for internal medicine diseases, selecting relevant content from medical works of past generations and categorizing them. It also includes You Zaijing's own medical views and treatment methods, making it highly practical for clinical use. Yixue Du Shu Ji is a collection of personal insights and clinical experiences from You Zaijing's studies and practice, containing many profound and concise arguments. Jing Xiang Lou Yi An records 32 categories of disease cases and their diagnostic analyses, treatment methods, and prescriptions, providing evidence for studying You Zaijing's treatment and prescription methods.
Excerpt:
p; Sunwind strikes, yang floats while yin is weak. Yang floats indicates heat spontaneously arises, while yin is weak indicates sweat spontaneously escapes. Shivering chills, gentle wind aversion, flushed fever, snoring dry heaving—Guaizhi Decoction is the remedy. Sunwind strikes means yang is affected by wind but not yet by yin, hence the pulse shows yang floats while yin is weak. Yang floats means heat arises without obstruction, while yin is weak means sweat escapes without stimulation. This is because wind is yang and ascends, while Wei Qi is yang and governs the exterior. Aligning with yang, its qi must float, hence heat arises. Yang strengthens with wind while yin weakens without pathogen, aligning with weakness, its qi must be frail, hence sweat escapes. Shivering chills and gentle wind aversion indicate loose skin and harmonious Wei Qi imbalance—though no cold exists, it feels unbearable, and though no wind exists, it feels perpetually damp. Flushed means heat is active and intense, unlike Shanghan where heat reaches its peak. Snoring dry heaving not only indicates wind obstructing the exterior but also sudden pathogen increase, with interior qi struggling upward. Thus, Guaizhi Decoction aids the body to expel pathogens, defending the exterior to calm the interior.
Guaizhi Decoction:
3 liang cinnamon bark (),
2 liang ginger (),
3 liang white peony root (),
3 liang fresh ginger (),
12 jujubes (),
Grind the five ingredients into coarse powder. Boil with 7 liters of water in a low flame to reduce to 3 liters. Strain and adjust to body temperature. Take 1 liter. After taking it, drink 1 liter of warm thin porridge to enhance efficacy. Cover and rest for about an hour until the body feels warm and slightly sweaty—this is ideal. Avoid excessive sweating like water flowing. If one dose induces sweating and symptoms improve, stop further doses. If no sweating occurs, take another dose following the same method. If still no sweating, take a third dose after half a day to complete the course. For severe cases, take it for a day and night, observing for a full cycle. If symptoms persist after one course, take another. If no sweating occurs after two courses, continue until effective. Avoid raw, greasy, meat, five pungent flavors, wine, curd, and foul-smelling foods.
Note: Wind as qi can activate yang and drain fluids, causing fever and spontaneous sweating—different from Shanghan's fever without sweat. This formula uses cinnamon to dispel pathogens while white peony root nourishes fluids. Acong ginger balances cinnamon's pungency, enough to defend the exterior and calm the interior. Fresh ginger and jujubes combine sweet and pungent flavors to replenish Ying and Wei, aiding the body to expel pathogens. Since sweating occurs without pathogen exiting, it avoids Ma Huang's exterior-dredging effect, using cinnamon to support exterior function. Since exterior disease exists without interior heat, it avoids Gypsum's interior-clearing effect, using white peony root to consolidate yin. This distinguishes Guaizhi Decoction from Ma Huang and Daqinglong Decoction.
Drink warm thin porridge after taking it to aid stomach qi, which in turn enhances efficacy—since medicinal efficacy relies on stomach qi to function. Cover to induce slight sweating, avoiding excessive flow like water, as sweating in moderation is self-healing while excessive sweating is overcorrection. If symptoms improve after one dose, stop further doses to avoid overcorrecting and harming the body. If no sweating occurs, take subsequent doses more frequently, or up to two or three courses, aiming for success through sweating as the sign of healing. Zhang Zhongjing teaches this method within methods.
For Sunwind disease with headache, fever, sweating, and aversion to wind—Guaizhi Decoction is the remedy. Since Sunwind is affected by pathogens, whether wind or cold, it causes headache and fever. But cold injury leads to exterior excess without sweat, while wind injury leads to loose exterior with spontaneous sweating. Thus, headache and fever are shared by both, while sweating and aversion to wind are unique to wind. Wind must be treated with wind formulas—mentioning Guaizhi Decoction as the remedy implies it cannot be replaced by other drugs.
For Sunwind disease with unresolved exterior symptoms and a floating-weak pulse—treatment should focus on sweating, using Guaizhi Decoction.
