Shanghan (Cold Damage) is difficult to treat; one must understand its adverse syndromes (prognostically unfavorable conditions). Yang-type diseases are feared when accompanied by Yin-type pulses. Delirium (incoherent speech due to mental confusion) in a Yin syndrome is inappropriate. A pulse that alternates between slow and rapid is a major taboo; an open mouth, sunken eyes, and a tongue black as coal indicate critical severity. Dry retching with weak breath, bone joint pain, and unceasing hiccups; appearance of macules/rash and jaundice, with free stool but color changing from red to grayish-black. Huoluan (acute vomiting and diarrhea) with restlessness, epigastric fullness, wheezing, and distension; abdominal bloating with hiccups, severe diarrhea, and difficulty urinating. Cold extremities (cold hands and feet), fixed gaze, and abdominal pain hard as stone; internal and external blockage (obstruction of Qi and Blood between interior and exterior), head sweating indicating Yang collapse, and delayed urination. Headache extending to the chest, cold limbs, hoarse voice, ulcers on lips, and sorrowful demeanor resembling Huhuo disease. High fever returning after seven days, wheezing with rebellious Qi, and a scattered pulse indicate danger. Yi Chang (transmission of pathogen via intercourse during recovery) presents with pulse deviating from normal, swelling of external genitals, spasms of hands and feet, and aggravated abdominal pain. Yin Yang Jiao (exhaustion of healthy Qi by pathogenic heat) presents with intense heat after profuse sweating, extreme restlessness, delirium, and loss of appetite. Jue Li (cold limbs and diarrhea) without a pulse, where moxibustion fails to restore the pulse, indicates impending Kidney failure; blue lips, curled tongue, deafness, and retraction of the testicles indicate Liver disintegration. Red macules and black macules: only one in ten can be saved; picking at empty air and clothes (signs of terminal coma): if it is Liang Gan (simultaneous involvement of exterior and interior meridians), doubt about prognosis is unnecessary. Regarding various sweating syndromes, they should be stated in detail: sweating confined to the head and face without covering the whole body, or continuous nosebleed (epistaxis); locked jaw, muscle tremors, and frequent wheezing, or oily sweat forming round beads that do not flow (terminal sweat). When sweating should occur but does not, and several doses of Mahuang Tang (Ephedra Decoction) fail to induce sweat, especially if the pulse is restless; after sweating, vomiting occurs, fluids and medicine cannot be retained, symptoms worsen, with confused speech and dizziness. Profuse sweating in patients with dampness inevitably leads to Jing Bing (spasm disorder). Rheumatism and jaundice treated incorrectly will both cause delirium. Contracting Shi Wen (damp-warmth) results in bluish body, altered facial complexion, deafness, and muteness, indicating severe illness. Developing into Shaoyin syndrome involves bleeding from nine orifices; lower Jiao coldness with upper Jiao exhaustion of fluids and blood is incurable. Any pulsation around the umbilicus (Dong Qi) with a slow and weak pulse contraindicates purgation; rheumatism and dampness in the middle Jiao cannot withstand harsh treatment. Regarding various dysenteries, careful analysis is required: heat-Jue with diarrhea and uncontrollable sweating; cold-Jue with diarrhea, restlessness, and insomnia; combined Shaoyang and Yangming disease with a wiry pulse indicates a negative outcome; Shaoyin disease with vomiting, diarrhea, absent pulse, cold limbs, and restlessness. Delirium, fixed gaze, wheezing, and chest fullness; frequent dysentery with a firm pulse. Zang Jie (organ knotting) presents with umbilical pain radiating to the genitals, white-coated tongue, and diarrhea. Chu Zhong (return of appetite before death, sign of stomach Qi exhaustion) presents with cold limbs, diarrhea, and sudden ability to eat. Incorrect purgation in dampness patients causes head sweating, difficult urination, free stool, and aggravated wheezing. Body yellow like smoked meat, shaking head, and fixed gaze indicate destruction of Heart Spirit; blue lips and excessive sweating on limbs indicate incomplete Liver Qi. Kidney exhaustion manifests as fixed gaze, delirium, enuresis, and upward-rolling eyes; Lung exhaustion manifests as ceaseless wheezing and moist, inverted hair. Deficient sweating, jaundice, and blackness around the mouth are auspicious signs for the Spleen channel? No, they are not auspicious signs. Lone Yang prevailing with a suddenly bursting pulse indicates Yin exhaustion occurring first. These are the adverse signs of Shanghan; do not rely on luck to seek survival.
