又用浓煎的甘草服用一剂，服药后肿痛立即消散。这两味药（甘遂与甘草）本性相反，必须让两个人分别购买，各自存放安置，千万不可混合在一起。清流厅官员韩咏深受此病困扰，服用一剂后病症去除了七八成，再服一次便痊愈了。据说这方子是从牛马牙人那里得来的，医者的用意，正是利用药物之间的相反相成之理。因此外用甘遂敷贴，内服甘草引导药力入内，从而取得疗效，其原理如同磁石吸引铁针一样。（均出自《医宗集成》。）
薛立斋治疗余举人第及，当时二十岁，腿部和膝盖肿痛，无法伸展弯曲，服用托里补益的药物反而加重病情。改用加味人参败毒散（加入槟榔、木瓜、柴胡、紫苏、苍术、黄柏），最终治愈。
黄锦芳治疗李某患香港脚（足部肿痛溃烂之症），疼痛剧烈到无法触碰，患处发热异常，且阴囊干燥开裂，瘙痒难忍。左手脉象极弦且数，右手脉象稍弱，饮食正常，只是时常感到空虚饥饿感，夜间烦躁不安，大小便不太通畅。这是体内火邪发动，而外部被风邪郁闭所致。不可使用辛温燥烈、追风逐湿的药物，应当大泻肝胆之火，则脚痛自然平息。使用泻青汤投予，取其方中龙胆草等药清泻厥阴肝经之火，防风祛除外受之风邪，大黄清除肠胃内部闭塞之热，服用一剂后症状减轻，再服后大便通畅而痊愈。随后令其服用六味丸，滋阴以善后调理。
雷作楫体质素来虚寒，加之嗜酒，导致少阴真火借酒性上浮，而脚底反而没有阳气护卫，一旦遇到寒气侵袭，脚就不能着地。乾隆甲申年春天，因脚筋抽搐疼痛，有人让他服用老贯草（一种草药），结果导致脚痛加剧无法活动。黄医生诊视，发现其脚部冷中带暖，必须用热手紧紧按压才能缓解，饮食不进，时常呕吐冷涎。选用姜汁炒制的半夏，并重加肉桂、附子、仙茅、乳香、没药、杜仲、续断等药物，大剂量煎服而愈。
王洪绪治疗鹤膝风（膝关节肿大如鹤膝之症），使用新鲜白芷，用酒煎煮成膏状，每日用陈年老酒送服，再取三钱药膏涂抹患处，直到肿块消退才停止。或者内服阳和汤，外用白芥子研为粉末，用酒酿调匀涂抹，也能自行消退。
Another case involved the decoction of Licorice Root (Gancao, 甘草) in high concentration for one dose; after ingestion, the swelling and pain immediately subsided. These two substances (Kansui Root and Licorice Root) are inherently incompatible. It was necessary for two people to purchase them separately and store them apart; they must never be mixed. Han Yong, an official at the Qingliu Hall, suffered from this condition. After one dose, seven or eight parts of the illness were eliminated, and after a second dose, he was cured. He obtained this method from a cattle and horse broker. The physician's intention was precisely to utilize their antagonistic properties. Thus, Kansui Root (Gansui, 甘遂) was applied externally, while Licorice Root (Gancao, 甘草) was taken internally to guide the therapeutic effect, achieving results akin to the principle of a lodestone attracting iron needles. (Both cases from *Yizong Jicheng*.)
Xue Lizhai treated Yu Ju-ren Dijí, who was twenty years old, suffering from swelling and pain in the legs and knees, unable to extend or flex them. Administration of internal-strengthening (Tuo-li) herbs aggravated the condition. He was cured using Ren Shen Bai Du San (Ginseng Decoction to Overcome Pathogenic Factors) modified with Areca Seed (Binglang, 槟榔), Quince (Mugua, 木瓜), Bupleurum Root (Chaihu, 柴胡), Perilla Leaf (Zisu, 紫苏), Atractylodes Rhizome (Cangzhu, 苍术), and Phellodendron Bark (Huangbai, 黄柏).
Huang Jinfang treated Li Mou for Hongxiangjiao (a condition characterized by foot swelling, pain, and ulceration). The pain was so severe that it could not be touched, and the area was abnormally hot. Additionally, the scrotum was dry and cracked, with unbearable itching. The pulse on the left hand was extremely wiry and rapid, while the right hand's pulse was slightly weaker. Dietary intake remained normal, but there was frequent sensation of hollow hunger. At night, he was irritable and restless, and bowel and bladder movements were not very smooth. This indicated an activation of internal fire, constrained externally by wind pathogens. Pungent, drying, wind-chasing, and damp-expelling herbs should not be used. Instead, the Liver and Gallbladder fire should be severely purged, which would naturally settle the foot pain. Xie Qing Tang (Drain Green Decoction) was administered. Its Gardenia Fruit (Zhizi, 栀子) and Gentian Root (Longdancao, 龙胆草) clear the fire of the Jueyin Liver channel; Fangfeng (Saposhnikovia Root) expels external wind; and Rhubarb (Dahuang, 大黄) removes internal heat obstruction in the stomach and intestines. Symptoms decreased after one dose, and upon the second dose, bowel movement became smooth, leading to recovery. Subsequently, Liu Wei Wan (Six-Ingredient Pill with Rehmannia) was prescribed to nourish Yin as a follow-up treatment.
Lei Zuojí had a constitution that was inherently cold, compounded by alcoholism. This caused the True Fire of Shaoyin to float upward due to alcohol, leaving the soles of the feet unprotected by Yang Qi. Upon exposure to cold, his feet could not touch the ground. In the spring of Jiashen year of Qianlong's reign, due to cramping pain in the leg tendons, someone advised him to consume Laoguancao (Old Vine Herb), which resulted in intensified foot pain and immobility. Physician Huang examined him, noting that the feet felt cold yet warm simultaneously, requiring firm pressing with warm hands to alleviate discomfort. There was no appetite, and cold saliva was frequently vomited. Processed Pinellia Tuber (Banxia, 半夏) fried in ginger juice was selected, heavily supplemented with Cinnamon Twig (Guizhi, 桂枝), Prepared Aconite Root (Fuzi, 附子), Curculigo Rhizome (Xianmao, 仙茅), Frankincense (Ruxiang, 乳香), Myrrh (Moyao, 没药), Eucommia Bark (Duzhong, 杜zhong), and Dipsacus Root (Xuduan, 续断). These were decocted in large doses and administered, resulting in a cure.
Wang Hongxu treated Hexixiang (Crane Knee Wind, characterized by knee joint enlargement resembling a crane's knee) using fresh Angelica Dahurica Root (Baizhi, 白芷). It was decocted in wine into a paste. Each day, it was taken orally with aged wine, and three qian of the paste were applied topically to the affected area until the swelling resolved. Alternatively, Yanghe Tang (Yanghe Decoction) could be taken internally, while white mustard seed powder mixed with fermented rice wine was applied externally, which also led to resolution.
