古方有用曲、 者，化水谷也、用 砂、阿魏者，去肉食也、用陈皮、紫苏、生姜者，
化鱼蟹也。用丁香、桂心者，腐果菜也。用牵牛、芫花者，攻水饮者。用三棱、鳖甲者，去
症瘕也。用附子、硫黄者，除痼冷也、用水蛭、虻虫者，攻血块也。用木香、槟榔者，攻滞
气也。用雄黄、腻粉者，攻涎积也。用礞石、巴豆者，攻痰食也。甘遂、甘草并用者，假其
相战以去积也。但立方之人，未入神妙，鲜有不类聚群毒以为丸者，此之谓猎不知兔，广络
原野，冀一人获之，术亦疏矣。今考古人神异数事于下，以广见闻。
《史记》曰∶临 女子薄吾病甚，众医以为寒热笃，当死。臣意诊其脉，曰蛲瘕，为病
腹大，上肤黄粗，循之戚戚然。臣意欲以芫花一撮，即出蛲可数升，病已，三十日如故。病
蛲得之于寒湿，寒湿气郁笃不发，化为虫。所以知薄吾病者，切其脉，循其尺，索刺粗而毛
美奉发，是虫气也。其色泽者，中脏无邪气及重病。昆谓仓公以病蛲得之寒湿者，谓寒水湿
土之气也。寒水湿土之气，郁极而不能宣发，则化为虫，所谓湿热生虫是也。芫花气身寒而
味苦辛，有毒，能下十二经之水而攻积聚，故能下水土生化之蛲。
北齐褚澄，善医术，建元中为吴郡太守，民有李道念者，以公事至郡。澄遥见谓曰∶汝
有奇疾。道念曰∶果得冷疾五年矣。澄诊其脉曰∶非冷也，由多食鸡子所致。令取蒜一升，
服之即吐物如升许，涎裹之动，抉涎出视，乃一鸡雏，翅距已具而能走。澄曰∶未也，盍服
其余？从之，又吐十三枚，疾乃瘳。昆谓蒜性辛热，可以壮气，正气壮，则病邪不能容，故
上涌而出，乃君子道长，小人道消之象。经曰∶壮者气行则愈，怯者着而成病。此之谓也。
古代医方中有使用神曲、麦芽的，是为了消化水谷积滞；有使用砂仁、阿魏的，是为了消除肉食积滞；有使用陈皮、紫苏、生姜的，是为了化解鱼蟹引起的不适；有使用丁香、桂心的，是为了腐熟果菜积滞；有使用牵牛子、芫花的，是为了攻逐水饮停聚；有使用三棱、鳖甲的，是为了消散症瘕积聚；有使用附子、硫黄的，是为了祛除顽固性寒邪；有用水蛭、虻虫的，是为了攻逐瘀血块；有使用木香、槟榔的，是为了行气导滞；有使用雄黄、腻粉（轻粉）的，是为了攻逐痰涎积滞；有使用礞石、巴豆的，是为了攻逐痰食互结。将甘遂与甘草并用的，是假借二者相互对抗的药性来消除积滞。但是制定这些方剂的人，尚未达到神妙境界，很少有不聚集多种有毒药物制成丸剂的，这叫做“猎不知兔，广络原野”，希望在其中捕获一只兔子，这种策略也太疏漏了。现在列举古代人神奇异事数则于下，以开阔见闻。
《史记》记载：临淄女子薄吾病重，众医生认为她是严重的寒热病，应当死亡。仓公（淳于意）诊察她的脉象，说是蛲瘕（一种因寄生虫或积滞导致的腹部肿块病），病症表现为腹部胀大，皮肤发黄粗糙，触摸时感觉坚硬拘急。仓公打算用一撮芫花，随即排出蛲虫可达数升，病愈后，三十天后身体恢复如常。患蛲瘕是因为感受寒湿之邪，寒湿气郁结深重不能发散，化为虫。之所以知道薄吾患的是蛲瘕，是因为切按她的脉象，循按尺肤，发现脉象索刺粗而毛发美盛奉起，这是虫气的表现。其面色光泽，说明内脏无邪气及重病。吴昆认为仓公说患蛲瘕得之于寒湿，是指寒水湿土之气。寒水湿土之气，郁结至极而不能宣发，则化为虫，这就是所谓的湿热生虫。芫花药性寒，味苦辛，有毒，能下行十二经之水而攻逐积聚，所以能排除由水土生化出的蛲虫。
北齐褚澄，擅长医术，建元年间担任吴郡太守。百姓中有个叫李道念的人，因公事到郡府。褚澄远远看见他说：“你有奇疾。”李道念说：“确实患有冷疾五年了。”褚澄诊察他的脉象说：“不是冷疾，是由多吃鸡蛋引起的。”让取蒜一升，服用后立即吐出约一升多的东西，涎液包裹着它在动，挑开涎液观看，竟是一只小鸡雏，翅膀和脚距都已长成且能行走。褚澄说：“还没完，何不把剩下的也服下？”听从了他的话，又吐出了十三枚，疾病才痊愈。吴昆认为蒜性辛热，可以壮大气机，正气壮盛，则病邪无法容留，所以上涌而出，这是君子道长、小人道消的象征。经文说：“壮者气行则愈，怯者着而成病。”说的就是这个道理。
Ancient medical formulas included the use of Shenqu and Maiya (Fermented Rice and Sprouted Millet) to digest food stagnation; Sharen and Awei (Amomum Fruit and Ferula Resin) to eliminate meat stagnation; Chenpi, Zisu, and Shengjiang (Tangerine Peel, Perilla Leaf, and Fresh Ginger) to resolve fish and crab-related discomfort; Dingxiang and Guixin (Clove and Cinnamon Heart) to rot fruit and vegetable stagnation; Qianniu and Yuanhua (Pharbitis Seed and Genkwa Flower) to attack water retention; Sanleng and Biejia (Burreed Tuber and Turtle Shell) to dissipate zhengjia (masses); Fuzi and Liuhuang (Prepared Aconite Root and Sulfur) to remove chronic cold; Shuizhi and Mengchong (Leech and Blue Bottle Fly) to attack blood stasis masses; Muxiang and Binglang (Aucklandia Root and Areca Nut) to attack qi stagnation; Xionghuang and Nifen (Realgar and Calomel) to attack phlegm accumulation; Mengshi and Badou (Lapis Lanati and Croton Seed) to attack phlegm-food binding. Using Gansui and Gancao (Kansui Root and Licorice Root) together relies on their mutual antagonism to eliminate accumulation. However, the formulators had not yet reached a state of divine subtlety; few did not gather various toxic substances to make pills. This is likened to "hunting without knowing where the rabbit is, spreading nets over vast fields," hoping to catch one rabbit by chance—a strategy that was indeed too crude. Now, several miraculous events from ancient times are listed below to broaden knowledge.
The *Records of the Grand Historian* states: Bo Wu, a woman from Linzi, was severely ill. Most physicians believed she suffered from severe chills and fever and would die. Chunyu Yi (the Earl of Cang) diagnosed her pulse as showing *Naojia* (a condition characterized by abdominal distension due to parasites or accumulation). The symptoms were an enlarged abdomen with yellowish, rough skin that felt hard and tense upon palpation. Chunyu Yi intended to administer a pinch of Yuanhua (Genkwa Flower), after which several sheng (a unit of volume) of nematodes were expelled, curing the disease. Thirty days later, she recovered fully. The *Naojia* was contracted from cold-dampness. When cold-damp qi stagnates deeply and fails to disperse, it transforms into worms. Chunyu Yi knew this was *Naojia* because palpating the radial artery and the skin at the cubital fossa revealed a coarse, prickly pulse texture with erect hair, indicative of worm qi. Her lustrous complexion indicated no pathogenic factors in the zang-fu organs or critical illness. Wu Kun interprets Chunyu Yi’s attribution of *Naojia* to cold-dampness as referring to the qi of Cold-Water and Damp-Earth. When these qis stagnate excessively and cannot be vented, they transform into worms, which aligns with the concept that damp-heat generates worms. Yuanhua has a cold nature and bitter-pungent taste; it is toxic but can descend water in the twelve meridians and attack accumulations, thus expelling nematodes generated from water and earth.
Chu Cheng of Northern Qi was skilled in medicine and served as the Prefect of Wu Commandery during the Jianyuan era. A commoner named Li Daonian came to the commandery for official business. Chu Cheng saw him from afar and said, "You have a strange disease." Daonian replied, "Indeed, I have suffered from a cold ailment for five years." Chu Cheng diagnosed his pulse and said, "It is not a cold ailment; it is caused by excessive consumption of chicken eggs." He ordered a sheng (unit of volume) of garlic to be taken. Upon ingestion, Daonian vomited approximately a sheng of material wrapped in saliva, moving within it. Upon examining the saliva, it was found to be a chick, complete with wings and spurs, capable of walking. Chu Cheng said, "Not yet. Why not take the remainder?" Daonian complied and vomited thirteen more eggs, after which the disease was cured. Wu Kun notes that garlic is pungent and hot, capable of strengthening qi. When righteous qi is strong, pathogenic factors cannot reside, leading to upward expulsion. This reflects the principle of "the way of the gentleman grows, while the way of the petty man declines." The Classic states: "Those who are robust recover as qi moves; those who are weak develop disease as pathogens adhere." This illustrates that principle.
