为秽为恐,(胃为水谷之海,肾与为关,关门不利,则气逆而上行也。以包容水谷,性善受寒,寒谷相

The "Xuan Ming Wu Qi Pian" (Chapter on the Manifestation of Five Qi) states: Regarding diseases caused by the dysfunction of the five zang organs' qi, the heart manifests as belching. This is because the heart corresponds to fire, and fire flares upward, like smoke following flames; the heart cannot tolerate turbid qi, so it expels it through belching. The lungs manifest as coughing. This is because the lungs correspond to metal, which is firm and resonant when struck; when pathogenic factors attack the lungs, coughing ensues. The liver manifests as excessive speech or inappropriate talking. This is because the liver corresponds to wood, with branches that are numerous and tortuous; speech expresses complex and subtle thoughts, hence it originates from the liver. The spleen manifests as frequent swallowing. This is because the spleen corresponds to earth, which has the capacity to contain all things; as substances return inward and are fully accepted, it manifests as swallowing. The kidneys manifest as yawning and sneezing. This is because the kidneys correspond to water, whose nature flows downward while mist rises above; when qi stagnates in the stomach, yawning occurs. When the qi of the Taiyang channel is harmonious and smooth, filling the heart and exiting through the nose, sneezing occurs. The stomach manifests as rebellious qi, retching of foul matter, and fear. This is because the stomach is the sea of water and grain, working with the kidneys as a gate; if the gate's function is impaired, qi rebels and moves upward. Since the stomach contains food and drink and is prone to cold, the clash between cold and food causes hiccups (yue). Excessive cold triggers hiccups, while excessive heat generates fear; why? Because stomach heat weakens kidney qi, leading to fear. The large intestine and small intestine manifest as diarrhea. The lower jiao overflowing with water results from dysfunction here. The large intestine is the fu organ of transmission, and the small intestine is the fu organ of reception and containment; when the qi of reception is deficient and the transmission lacks control, diarrhea occurs. The lower jiao is the site of fluid distribution; when qi is obstructed and cannot drain, fluids overflow. Bladder dysfunction leading to difficulty in urination is called strangury (long), and lack of restraint leads to enuresis. The bladder is the fu organ of body fluids, where water accumulates. If the foot Sanjiao pulse is excess, constraining the lower jiao without unblocking it causes urinary retention; if the foot Sanjiao pulse is deficient, failing to constrain the lower jiao leads to enuresis. The gallbladder manifests as anger. This is because the gallbladder governs justice and decision-making, being impartial and unbiased, with a rigid and decisive nature, hence anger. These are referred to as the five diseases.
Regarding the merging of the essence of the five zang organs: When essence merges into the heart, joy ensues. Here, "essence" refers to the essence of fire. If lung qi is deficient and heart essence merges into it, joy occurs. The *Ling Shu* states: "Unrestrained joy damages Po." Po is the spirit of the lungs, indicating that heart fire merges into lung metal. When essence merges into the lungs, sorrow ensues. If liver qi is deficient and lung essence merges into it, sorrow occurs. The *Ling Shu* states: "Sorrow moving within damages Hun." Hun is the spirit of the liver, indicating that lung metal merges into liver wood. When essence merges into the liver, worry ensues. If spleen qi is deficient and liver essence merges into it, worry occurs. The *Ling Shu* states: "Unresolved worry damages Yi." Yi is the spirit of the spleen, indicating that liver wood merges into spleen earth. When essence merges into the spleen, fear ensues. If kidney qi is deficient and spleen essence merges into it, fear occurs. The *Ling Shu* states: "Unresolved fear damages Jing." Jing is the spirit of the kidneys, indicating that spleen earth merges into kidney water. When essence merges into the kidneys, fright ensues. If heart qi is deficient and kidney essence merges into it, fright occurs. The *Ling Shu* states: "Fright and overthinking damage Shen." Shen is the spirit of the heart, indicating that kidney water merges into heart fire. "Chu Ti" means fright. These are all cases where healthy qi is insufficient and is overtaken by pathogenic qi. This is called the "Five Merges," referring to the mutual merging of essence due to deficiency.
The five things the zang organs dislike: The heart dislikes heat, which makes vessels slippery and turbid. The lungs dislike cold, which causes qi stagnation. The liver dislikes wind, which dries and tightens tendons. The spleen dislikes dampness, which causes muscle flaccidity and swelling. The kidneys dislike dryness, which exhausts essence. This is called the "Five Dislikes."
The prohibitions regarding the five flavors: Pungent flavor travels to qi; those with qi disorders should not consume excessive pungent foods. Salty flavor travels to blood; those with blood disorders should not consume excessive salty foods. (Salty flavor enters the kidneys first; saying it travels to blood is because the kidneys connect with the Sanjiao. Although vessels belong to the heart and liver, they are actually pathways of the Sanjiao, so salty flavor enters and travels to blood.) Bitter flavor travels to bones; those with bone disorders should not consume excessive bitter foods. (Bitter flavor travels to the heart; saying it travels to bones is because water and fire mutually assist, and bone qi connects with the heart.) Sweet flavor travels to flesh; those with flesh disorders should not consume excessive sweet foods. Sour flavor travels to tendons; those with tendon disorders should not consume excessive sour or pungent foods. This is called the "Five Prohibitions."
The sites where the five diseases manifest: Yin diseases manifest in bones; Yang diseases manifest in blood vessels; Yin diseases manifest in flesh. (Bone and flesh are yin and still, so yang qi attaches to them; blood vessels are yang and active, so yin qi attacks them.) Yang diseases manifest in winter; Yin diseases manifest in summer. (Summer is abundant in yang qi, so yin diseases manifest then; winter is abundant in yin qi, so yang diseases manifest then. Each follows the area of deficiency.) This is called the "Five Manifestations."
The disturbances caused by the five pathogens: Pathogens entering yang cause mania; pathogens entering yin cause bi syndrome. (When pathogens reside in yang meridians, limbs become excessively hot, causing mania. When pathogens enter yin meridians, the six channels become stagnant and blocked, causing bi syndrome.) Pathogens clashing with yang cause head diseases; pathogens clashing with yin cause aphonia. (When pathogens clash internally with yang, vessel flow becomes rapid, causing head diseases. When pathogens clash with yin, vessel flow stops, causing aphonia and inability to speak.) Yang entering yin causes quietness; yin emerging to yang causes anger. (Diseases arise according to where the pathogen goes. "Zhi" means to go.) This is called the "Five Disturbances."
The injuries caused by the five labors: Prolonged viewing damages blood (laboring the heart); prolonged lying down damages qi (laboring the lungs); prolonged sitting damages flesh (laboring the spleen); prolonged standing damages bones (laboring the kidneys); prolonged walking damages tendons (laboring the liver). This is called the "Injuries of the Five Labors."
