The general principle for treating Cold Damage in spring is to use emesis. (Zhang Zhongjing states: The general principle is that emesis is suitable in spring.) When retained food fails to digest, causing chest fullness and Zhu disease (a condition characterized by wandering pain or infectious symptoms), [the patient] should be treated with emesis. (The *Jin Gui Yu Han Jing* states: If retained food is located below the epigastrium, emesis should be used.) There is a sense of oppression in the chest accompanied by saliva and phlegm.
The cause can be known from the Cun (inch) position of the pulse being slightly rapid. (The *Jin Gui Yu Han Jing* states: If there is solidity above the chest, oppression and pain in the chest, inability to eat, and pressing on the area elicits saliva and phlegm, along with frequent diarrhea more than ten times a day, a slow pulse generally but a slightly slippery pulse at the Cun position, this is a case where emesis is indicated. The above are all indications for emesis.) However, if the pulse is faint, emesis is contraindicated as it would be a major deviation. (Zhang Zhongjing states: A faint pulse indicates emesis is contraindicated; a deficient and fine pulse indicates purgation is contraindicated.) In Shaoyin cold-fluid retention syndromes, if the condition does not worsen, emesis is not appropriate. (Zhang Zhongjing states: In Shaoyin disease, if the patient vomits immediately after eating, feels a warm sensation of wanting to vomit but cannot, starts with cold hands and feet, and has a string-tight and slow pulse, this indicates excess in the chest which should be treated with purgation. If there is cold fluid above the diaphragm causing dry retching, emesis is contraindicated, and warming treatment should be used instead.) For patients with Sini syndrome (Cold Extremities) or those who are constitutionally deficient, only warming methods are permissible. Mistakenly using emesis leads to internal irritability; who will bear the responsibility? (The *Jin Gui Yu Han Jing* and *Jin Gui Yao Lue* state: Sini syndrome with cold extremities is contraindicated for emesis, as is the case for constitutionally deficient individuals. It also states: For Taiyang disease, forcing emesis leads to internal irritability. These discussions all indicate cases where emesis is contraindicated.)
In Wind Strike, sudden exposure to fire therapy (fire劫) causes throat ulceration, jaundice, and exhaustion of body fluids. (Zhang Zhongjing states: In Taiyang Wind Strike, using fire therapy to force sweating causes the pathogenic wind to be constrained by fire, leading to stagnant blood and qi flow, resulting in jaundice and eventually throat ulceration.) With deficient Ying Qi (Nutritive Qi) and weak blood, combined with burning needle therapy, irritability, coma, and fever may occur simultaneously. (Zhang Zhongjing states: A deep pulse indicates deficient Ying Qi. Adding burning needle therapy causes blood stagnation, leading to increased fever and irritability.) Yangming disease subjected to fire therapy inevitably leads to fear and apprehension. (The *Jin Gui Yu Han Jing* states: In Yangming disease with a floating and tight pulse, adding burning needle therapy inevitably causes fear and apprehension.) Taiyang disease subjected to fire therapy inevitably leads to defecation of blood. (Zhang Zhongjing states: If Taiyang disease is fumigated with fire without inducing sweat, the patient becomes restless. If the condition persists beyond the expected course, defecation of blood will occur.) Fire therapy on Shaoyin disease makes urination difficult; forcibly demanding sweat creates further calamity. (Zhang Zhongjing states: In Shaoyin disease, coughing with diarrhea and delirium are caused by fire therapy. Urination will necessarily be difficult because forcibly demanding sweat from Shaoyin disease was attempted.) This may result in deficiency irritability and insomnia, or jaundice with central chest oppression, or defecation of blood resembling pig liver, or delirious speech without restraint. (Zhang Zhongjing states: Adding warm needle therapy to Yangming disease causes irritability and insomnia. Fire therapy on Yangming disease causes sweat on the forehead and inevitably leads to jaundice. Stagnant heat in the Bladder accumulates into masses, leading to defecation of blood resembling pig liver. Fire therapy on Taiyang or Yangming disease inevitably causes delirium.) All these are diseases caused by mistaken fire therapy; careful differentiation is essential. Zhang Miao sought to induce sweating by welcoming it from the exterior, yet he chose to heat the ground and spread peach leaves for steaming. (Chen Linqiu asked Zhang Miao: What if sweating cannot be induced despite repeated attempts? Zhang Miao replied: One can also heat the ground, spread peach leaves, and use the moist steam to welcome sweat from the exterior, thereby inducing sweating.)
