Treats Yin-Yang Yi (Yin-Yang Exchange Disease).
Take the garment near the female's genitalia, cut it into pieces and burn it to ash. Mix with water and administer one Fangcun Bi (a traditional Chinese measure for powder, approx. 1 cubic inch) at a time. Take three times daily. When urination becomes smooth and the glans penis/vulva swells slightly, the patient will recover.
If it is a male suffering from this condition, take the male's garment, burn it, and administer it.
The Song states:
Cut the crotch area of the underwear near the genitals and burn it;
Grind into powder and mix with water.
Seeking resonance in similar Qi to treat the two types of "Yi" exchange;
The formulas of Changsha (referring to Zhang Zhongjing's *Shanghan Zabing Lun*) are unsurpassed in excellence.
Zhang Yinan says:
The crotch area is the precise site where Jing (Essence) is exhaled and injected. It is likely that by taking the residual Qi of the other party, one can seize and eliminate the residual pathogenic factors of the other party. Since the pathogenic toxin originally entered through the Yin region, it is now made to exit through the Yin region. Therefore, it is said that when urination is smooth and the glans swells slightly, recovery is indicated.
It is the primary formula for cases where illness recurs due to overexertion after a major disease has healed. If there is retained food, add Da Huang (Rhubarb Root).
Zhi Shi (Immature Bitter Orange, 3 pieces, processed with heat), Zhi Zi (Gardenia Fruit, 14 pieces), Xiang Chi (Prepared Soybean, 1 Sheng).
Take the above three herbs, boil them in 7 Sheng of Qing Jiang Shui (Clear Fermented Grain Water) until reduced to 4 Sheng. Add Zhi Shi and Zhi Zi, boil until reduced to 2 Sheng. Then add Xiang Chi, boil for five or six more boils.
Strain the dregs. Take warm, divided into two doses. Cover the patient to induce a slight sweat.
The Song states:
One Sheng of Xiang Chi combined with three pieces of Zhi Shi;
Fourteen Zhi Zi can cover the various manifestations of post-illness recurrence. (*Shanghan Lun* only uses the six characters "recurrence after major illness due to labor" to summarize, without specifying the clinical presentation.)
Decoct with Jiang Shui to induce slight sweating; if food stagnation exists, rely on Da Huang to open the blockage.
Zhang Yinan says:
After a major illness heals, the Yin and Yang, Water and Fire begin to interact. Overexertion of the body leads to internal deficiency of Qi and Blood, causing the disease to recur. The symptoms vary, so the specific clinical presentation is not detailed; instead, this formula is used to govern all such cases. In the formula, Zhi Zi clears the irritant heat of the Upper Jiao (Upper Burner); Xiang Chi opens the fluid metabolism of the Lower Jiao (Lower Burner); roasted Zhi Shi promotes the Qi circulation of the Middle Jiao (Middle Burner). Once the Three Jiaos are harmonized, three hundred and ninety-seven treatment methods arise immediately. Methods are executed through formulas, and formulas are established through methods. This opens the medical perspective for thousands of years; it cannot be regarded merely as a single formula. After Zhang Zhongjing, this Dao gradually became obscure. It was not until the Tang Dynasty that Sun Simiao rose to clarify it, writing the *Qianjin Fang*. All its formulas were derived from the patterns of *Shanghan Lun*, which he recorded completely without omission. Unfortunately, his text had additions and omissions, and chapters were rearranged. He failed to elucidate the profound mysteries, being merely eager to imitate and transform the formulas in *Shanghan Lun* to seek novelty. Furthermore, in his sequel *Qianjin Yifang*, he established separate sections for nourishing nature and tonification. This led later physicians to cater to the wealthy by promoting formulas for tonifying Spleen and Kidney, dual tonification of Qi and Blood, warm and cool tonifications, and neutral tonifications. This vulgar practice gradually opened up. Ultimately, this is not the fault of *Qianjin Fang*, but the fault of those who do not know how to read it properly. If later students take its strengths and discard its weaknesses, then *Qianjin Fang* is indeed the wing of Zhang Zhongjing's works. Sun Simiao privately revered Zhongjing, often feeling as if he could see him face-to-face. His formulas claimed to be secret prescriptions from the Dragon Palace, likely because Zhongjing resided at Wolong Gang, making his *Shanghan Jin Gui Fang* synonymous with the Dragon Palace Prescriptions. Old sayings suggest that when the spirit is exhausted, spirits and ghosts reveal secrets; is it truly divine revelation?
My father lost his father early in life and lived in poverty. Half his time was spent on civil service examinations, and half on medicine. He saw daily how physicians competed in compiling various formularies from the Tang and Song dynasties, as well as the works of the Four Great Masters of Jin and Yuan (Liu, Zhang, Zhu, Li), and later figures like Wang Yutai, Xue Lizhai, Zhang Jingyue, and Li Shicai, indiscriminately collecting formulas into books. Consequently, books containing formulas circulated widely, while fundamental classics without formulas—such as *Shennong Bencao Jing*, *Huangdi Neijing*, *Nanjing*, and Zhongjing's works based on Yi Yin's *Tangye Jingfa*—were neglected. He pitied this situation greatly. He often wished to burn his family's collection of formula books, yet devoted decades to studying the classics and Zhongjing's texts without tiring. He found little to criticize in works below *Qianjin Fang*.
In the Renzi year, after passing the provincial examination, I resided in the capital. At that time, Mr. Yi Yunlin suffered from stroke, losing consciousness, with hemiplegia, unable to take soup or rice for over ten days. Famous doctors in the capital all declared it incurable. My father revived him with two large doses, gaining fame overnight. Patients filled the courtyard outside his door. Later, an official forced him to stay as a private physician; he refused, offending the official. In the autumn of the Guichou year, he returned home citing illness. Later, when that official took office in the Ji Fu region, fearing my father's medical fame would repeat the previous incident, my father ceased discussing medicine publicly, though he continued writing privately. He once told me: "Establishing words is one of the three immortals' deeds, excluding eight-legged essays and poetry. If someone can clarify the Dao of Zhongjing, free from heterodox studies, benefiting people from premature death and disease, their merit will extend to the world and future generations." Previous publications like *Gongyu Yilu* were annotated after the Ji Mao year in Baoyang. For over a thousand years, they existed in obscurity, until today when their true essence was realized, differing greatly from popular medical books. The difficulty lies in the precise dosage, order of decoction, and administration methods (divided doses, single dose, warm, cool, etc.), where a slight difference leads to vast discrepancies. Thus, I had to follow common editions and compile them into songs for memorization. I instructed Yu to draft annotations for each song, which my father revised personally. Where Yu offered unique insights, he circled and dotted them repeatedly, intending to awaken physicians from their lethargy. As for the *Jin Gui Fang*, he ordered my brother Yuanxi to rhyme them. I followed the style of Xu's *Neitai Fangyi* from Jian'an, providing commentary for each clause. Given my father's advanced age and limited energy, my brother and I merely performed filial duties, not daring to write lightly. Dated the fifth day after Winter Solstice, Ji Mao year, 24th Year of Jiaqing. Son Yu respectfully records.
Yu adds: The above annotations and notes were personally approved by my father. After printing, I often wished to add unfinished explanations, planning to publish several more items to avoid leaving loose ends. However, upon reading the *Six Medical Books* by the contemporary scholar Xu Lingtai, whose first volume contains six clear and lucid discussions, I felt no need to continue. I append them here to share with fellow enthusiasts.
