肝热病者先左颊赤，肺热病者先右颊赤，心热病者颜先赤，（颜，额也。）肾热病者颐先赤，
（颐，颊也。）脾热病者鼻先赤。（土主中央。）病虽未发，见赤色刺之，名曰治未病。
肝热病者，先小便黄，腹痛多卧身热。热争则狂言及惊，胁满痛，手足躁，不
得安卧，庚辛甚，甲乙大汗，气逆则庚辛死。刺足厥阴、少阳。其逆则头痛 ，脉引冲头也。
心热病者，先不乐，数日乃热。热争则卒心痛，烦闷喜呕，头痛面赤无汗，壬癸甚，丙丁大汗，
气逆则壬癸死。刺手少阴、太阳。
脾热病者，先头重颊痛，心烦颜青，欲呕身热。热争则腰痛，不可俯仰，腹满泄，两颔痛，甲
乙甚，戊己大汗，气逆则甲乙死。刺足太阴、阳明。
肺热病者，先淅然厥，起毫毛，恶风寒，舌上黄身热。热争则喘咳，痛起走胸膺背，不得太息，
头痛不任，汗出而恶寒，丙丁甚，庚辛大汗，气逆则丙丁死。刺手太阴、阳明，出血如豆大，立已。
肾热病者，先腰痛 酸，苦渴数饮水身热。热争则项痛 澹澹然，戊己甚，壬癸大汗，气逆
则戊己死。刺足少阴、太阳。诸汗者，至其所胜日汗出也。
庞曰∶五种热病，肝肾二脏有逆证，心脾肺三脏亡逆证。凡五种热病，二三日逢克未为逆，忌
在五六日也。
The *Suwen* (Basic Questions) records five types of heat diseases: Patients with Liver Heat Disease first exhibit redness on the left cheek; patients with Lung Heat Disease first exhibit redness on the right cheek; patients with Heart Heat Disease first exhibit redness on the forehead (Yan, meaning the forehead); patients with Kidney Heat Disease first exhibit redness on the chin (Yi, meaning the lower part of the cheek/jaw); patients with Spleen Heat Disease first exhibit redness on the nose. (In Five Elements theory, Earth governs the center.) Even if the disease has not yet fully manifested, puncturing upon seeing redness is called "treating before disease arises" (Zhi Wei Bing).
Patients with Liver Heat Disease first present with yellow urine, abdominal pain, lethargy, and body fever. When pathogenic heat contends with healthy Qi (Re Zheng), they may manifest delirious speech and惊厥 (convulsions), distension and pain in the hypochondrium, restlessness of the hands and feet, and inability to lie down comfortably. The condition worsens on Geng-Xin days, resolves with profuse sweating on Jia-Yi days, and death occurs due to Qi reversal on Geng-Xin days. Treatment involves puncturing the Foot-Jueyin (Liver) and Foot-Shaoyang (Gallbladder) meridians. If Qi reverses, it leads to headache, as the meridian Qi rushes upward to the head.
Patients with Heart Heat Disease first present with dissatisfaction or depression, developing fever after several days. When pathogenic heat contends with healthy Qi, they experience sudden heart pain, oppression, a tendency to vomit, headache, facial redness, and absence of sweat. The condition worsens on Ren-Gui days, resolves with profuse sweating on Bing-Ding days, and death occurs due to Qi reversal on Ren-Gui days. Treatment involves puncturing the Hand-Shaoyin (Heart) and Hand-Taiyang (Small Intestine) meridians.
Patients with Spleen Heat Disease first present with heavy head, cheek pain, irritability, bluish-green complexion, nausea, and body fever. When pathogenic heat contends with healthy Qi, they experience lower back pain, inability to bend forward or backward, abdominal fullness, diarrhea, and pain in both mandibles. The condition worsens on Jia-Yi days, resolves with profuse sweating on Wu-Ji days, and death occurs due to Qi reversal on Jia-Yi days. Treatment involves puncturing the Foot-Taiyin (Spleen) and Foot-Yangming (Stomach) meridians.
Patients with Lung Heat Disease first present with chills, erection of fine hairs, aversion to wind and cold, yellow tongue coating, and body fever. When pathogenic heat contends with healthy Qi, they experience wheezing and coughing, pain wandering across the chest, epigastrium, and back, difficulty taking deep breaths, unbearable headache, sweating, and aversion to cold. The condition worsens on Bing-Ding days, resolves with profuse sweating on Geng-Xin days, and death occurs due to Qi reversal on Bing-Ding days. Treatment involves puncturing the Hand-Taiyin (Lung) and Hand-Yangming (Large Intestine) meridians, releasing blood drops the size of a bean, which stops the symptoms immediately.
Patients with Kidney Heat Disease first present with soreness and pain in the lower back, bitter dry mouth with frequent desire to drink, and body fever. When pathogenic heat contends with healthy Qi, they experience neck pain and a sensation of internal turbulence. The condition worsens on Wu-Ji days, resolves with profuse sweating on Ren-Gui days, and death occurs due to Qi reversal on Wu-Ji days. Treatment involves puncturing the Foot-Shaoyin (Kidney) and Foot-Taiyang (Bladder) meridians. All such sweating occurs on the days when the affected organ's element is overcome by or overcomes others (days of resolution).
Pang Anshi stated: Among these five heat diseases, the Liver and Kidney organs have adverse conditions (Qi reversal), while the Heart, Spleen, and Lung organs do not have adverse conditions. For all five heat diseases, encountering an overcoming day within two to three days of onset is not considered adverse, but one must beware of encountering an overcoming day on the fifth or sixth day.
