Qian Yi stated: When children sweat naturally during sleep, it is due to deficiency of the muscles. Treat with Zhihan San (Stop Sweat Powder); if sweating occurs all over the body, treat with Xianggua Wan (Melon Pill).
Xue Ji stated: Spontaneous sweating belongs to Yang deficiency, while night sweats belong to Yin deficiency. This is because Yang constitutes Wei Qi (Defensive Qi), and Yin constitutes Ying Blood (Nutritive Blood). The Heart governs blood, and the Liver stores blood. Heat pathogens congregate in the Heart, causing fluids to fail to remain internalized and instead leaking out through the skin. When a person lies down, stillness corresponds to Yin; when awake, movement corresponds to Yang. Therefore, spontaneous sweating is attributed to Yang [imbalance], and night sweats to Yin [imbalance]. This often arises from the failure of communication between the Heart and Kidney, where Water and Fire fail to interact harmoniously (i.e., the physiological balance of Heart Fire descending and Kidney Water ascending is disrupted). Kidney deficiency leads to the loss of the storing and closing function, resulting in this symptom. If caused by blood deficiency with internal heat, use Danggui Liuhuang Tang (Angelica Hexang Decoction); if there is heat in the Heart Meridian, use Daochi San (Guide Out Red Powder); if there is deficient heat in the Liver Meridian, use Liuwei Wan (Six-Ingredient Pill); for night sweats due to blood depletion, use Danggui Buxue Tang (Angelica Tonifying Blood Decoction); for Wind-Heat in the Liver and Gallbladder, use Chaihu Qinggan Tang (Bupleurum Clearing Liver Decoction).
The nine orifices of the human body take their imagery from the Tai hexagram (Hexagram 11, Peace). The eyes, ears, and nose each have two orifices facing each other; the Yin number is even, forming the outer layer of the Kun hexagram (Earth) with three evens. The mouth and the two excretions (urine and feces) each have one orifice connected; the Yang number is odd, forming the inner layer of the Qian hexagram (Heaven) with three odds. Outer Kun and Inner Qian constitute the Tai hexagram. Heaven and Earth generate humans; although the essence is subtle and vast, it is always upright and not absurd. By correlating hexagrams with physical forms, diseases arise from here. The ear orifice belongs to the Kidney; its diseases include deafness or hearing loss, caused by either Fire pathogens or deficiency, with Liver pathogens also causing harm. The eye is the orifice of the Liver; its diseases are difficult to control, mostly belonging to Fire, combined with pathogenic Wind, sometimes due to internal deficiency, and occasionally due to Cold stagnation. Swelling and pain are mild, but severe cases present with nebulae (corneal opacity), tearing, photophobia, and a sensation of heaviness and obstruction. The nose opens into the Lung; when Metal of the Lung is invaded by pathogens, nasal congestion and stuffiness occur, with constant clear rhinorrhea, occasional sneezing, epistaxis (nosebleed), and nasal sores, indicating Lung Heat that cannot be vented. Nasopharyngitis (Bi Yuan) and nasal polyps require treatment involving the brain. The lips and mouth belong to the Spleen; excessive heat causes cracking, aphthous ulcers, and oral candidiasis (mouth rot), harming each other mutually. Teeth are the surplus of bone; disease manifests as gingival ulceration and rot, involving exhaustion of the Kidney, Spleen, and Liver. The tongue is the sprout of the Heart; symptoms include tongue protrusion disorders, coating generated by Dampness and Food Stagnation, and blackish-purple discoloration from Fire. Double tongue (swelling of the sublingual vein resembling a second tongue) and wooden tongue (stiffness and numbness of the tongue) are critical conditions. As for the throat and pharynx, they are the convergence points for respiratory Qi. Various malignant conditions such as laryngeal herpes (Hou Xuan), pharyngolaryngeal obstruction (Hou Bi), tonsillar suppuration (Hou E), and glottic closure (Hou Bi) must be carefully examined. These diseases can endanger life in an instant; clearing Fire and expelling Phlegm are the essential treatments. If accompanied by thirst or dryness with successive swelling and pain, it remains a mild condition, resolvable by clearing heat. All upper-orifice diseases gather into one category. For any illness, urgent treatment without negligence is required; analyze by meridian and syndrome to prevent deterioration. As for the anterior and posterior yin openings, belonging to the lower part, they are discussed separately to define distinct boundaries.
