子和吐武篇云∶凡病在上者，皆宜吐。然自胸以上，大满大实，病如胶漆，微汤微散皆
儿戏也。若非吐法，病安能除？曾见病之在上者，诸医用药尽其技而不效，余以涌剂少少
用之，辄获微效。可见吐法必可用于上，宜乎其效之速也。

以涌泻，复服益元散，加青黛、薄荷末调二三服，前证俱减。戴人诊之曰∶此病常欲痛哭为快，
妇曰∶然，常有此，不知何谓。戴人曰∶少阳相火凌烁肺金，金受火制，屈无所告。肺主悲，
故欲痛哭而为快也。再加归、芍、黄连解毒汤数剂
全瘥。

The "Zihe's Chapter on Vomiting" states: For all diseases located in the upper part of the body, the method of inducing vomiting (Yong Fa) is appropriate. However, from the chest upwards, if the condition presents with severe fullness and excess, where the pathogenic factor adheres like glue or lacquer, mild decoctions or powders are as ineffective as child's play. Without the method of inducing vomiting, how can the disease be eliminated? I have seen cases of diseases in the upper part where various physicians exhausted their skills with medication without effect; when I used emetics in small amounts, slight efficacy was immediately obtained. This shows that the method of inducing vomiting must be applicable to upper disorders, and its rapid effect is indeed reasonable.
I treated a woman who suffered from heavy head, high fever with red face, alternating chills and fever, dry retching and coughing with rebellious Qi, pain in the chest and hypochondrium preventing turning or side-lying, tinnitus, and inability to eat. Initially, I employed purgation/vomiting methods, followed by administering Yi Yuan San (Benefit Prime Powder), mixed with Qing Dai (Indigo Naturalis) and Bo He (Mint) powder, taken for two or three doses, after which all previous symptoms decreased. Dai Ren (Zhang Congzheng) diagnosed and said: "This patient often feels relief only after weeping bitterly." The woman replied: "Yes, this happens often, but I do not know why." Dai Ren said: "This is Shaoyang Ministerial Fire scorching Lung Metal. Lung Metal is constrained by Fire, feeling wronged with nowhere to complain. Since the Lung governs sorrow, she desires to weep bitterly to feel relieved." Subsequently, Gui (Danggui, Radix Angelicae Sinensis), Shao (Baishao, Radix Paeoniae Alba), and Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) were administered for several doses, resulting in complete recovery.
Danxi treated a young woman with an irritable temperament and preference for rich flavors. In summer, due to great anger, she developed coughing with rebellious Qi, whole-body tremors, and unconsciousness. Observing that her physical form and Qi were both substantial, he said: "There is phlegm above the diaphragm, compounded by anger and stagnation. Phlegm and Heat struggle together, preventing Qi from descending. Inducing vomiting is indispensable." He prepared a decoction of Renshen Lu (Ginseng Rhizome Stalk) for drinking, which induced massive vomiting of stubborn phlegm (several bowls). After sleeping for one day, she became stable. Renshen (Ginseng) enters the Hand-Taiyin Lung Meridian, tonifying Yin within Yang; conversely, the stalk (Lu) strongly drains Yang within Taiyin. The woman's sudden anger caused Qi to rebel upward. The Liver governs anger, and the Lung governs Qi. Anger causes Qi rebellion; Liver Wood overacts upon and insults Lung Metal, causing coughing with rebellious Qi and unconsciousness. Now that the phlegm is exhausted, Qi descends, Fire subsides, Metal Qi returns to its proper position, and Stomach Qi harmonizes, leading to resolution.
