Treatment of various "Fu" (Rebound) conditions follows specific principles: For Wind Fu, treat with Sour-Cold herbs, assist with Sweet-Acrid herbs, drain with Salty herbs, and relax tension with Sweet herbs. For Heat Fu, treat with Salty-Cold herbs, assist with Bitter-Acrid herbs, drain with Sweet herbs, astringe with Sour herbs, disperse with Bitter-Acrid herbs, and soften hardness with Salty herbs. For Dampness Fu, treat with Bitter-Hot herbs, assist with Sour-Acrid herbs, and drain, dry, and purge with Bitter herbs. For Fire Fu, treat with Salty-Cold herbs, assist with Bitter-Acrid herbs, astringe with Sour herbs, and disperse with Bitter-Acrid herbs. When releasing the exterior, do not avoid Hot herbs, but avoid violating the balance with Warm or Cool properties unnecessarily. The Shaoyin channel adopts the same method. For Dryness Fu, treat with Acrid-Warm herbs, assist with Bitter-Sweet herbs, drain with Bitter herbs, and tonify with Sour herbs. For Cold Fu, treat with Salty-Hot herbs, assist with Sweet-Acrid herbs, and consolidate righteousness with Bitter herbs.
"Fu" refers to a rebound condition that occurs following a "Sheng" (Excess/Dominant) condition. (New addition) For example, when Shaoyang (Ministerial Fire) qi descends, Lung Metal qi succeeds it, causing Metal to be affected by pathogens, resulting in symptoms such as wheezing, cough, and headache. Lung Metal generates Kidney Water; if pathogens transmit to the Kidney, symptoms include umbilical and abdominal pain, swelling and pain in the legs and feet, and cold body. Water is the child of Metal, and Water controls Fire. Metal and Water generate each other, and the child and mother jointly restrain Fire; this is the child saving the mother, which is named "Fu". Treatment should tonify the child organ (Kidney) to break the excessive Liver Wood qi. For Wind Fu, treat with Sour-Cold herbs, assist with Sweet-Acrid herbs, drain with Salty herbs, and relax with Sweet herbs. When Wood qi is excessive, Earth qi is affected. Earth generates Metal. Treating with Sour-Cold herbs works because Sour tonifies Metal, and Cold removes Heat. Further assisting with Sweet-Acrid herbs: Sweet tonifies Spleen and drains excessive Fire, while Acrid assists Lung Qi to drain pathogenic factors. Draining with Salty herbs is indicated because the Spleen benefits from Salty taste (note: context-specific), and the Kidney acts as the gatekeeper for the Stomach; Salty has a softening nature that facilitates the opening of these gates. The treatment for other Fu conditions like Dampness, Fire, Dryness, and Cold is similar.
(Old Canon) In treating all Sheng-Fu conditions, use Cold to treat Heat, Hot to treat Cold, Clear to treat Warm, and Warm to treat Clear. Use Sour to astringe scattered Qi and relieve urgency, Acrid to disperse stagnation and moisten dryness, Sweet to relieve urgency, Salty to soften hardness, Bitter to consolidate fragility, and drying agents to remove dampness. Drain excess and tonify deficiency, aiming for balance. Ensure Qi is peaceful, and the disease will resolve. If there is a Sheng arrival without a subsequent Fu, it is called "Earth Sheng" (Dominance from below). Disease due to upper dominance requires methods that follow Earth Qi and oppose Heaven Qi. Disease due to lower dominance affecting the upper part is called "Heaven Sheng," requiring methods that follow Heaven Qi and oppose Earth Qi to control it. When Fu arrives, distinctions based on Heaven and Earth names are discarded, and treatment follows the laws of Fu Qi strictly. However, changes in Sheng-Fu, though having fixed positions, do not necessarily occur inevitably. The upper three Qi (Jueyin, Shaoyin, Taiyin) are governed by Heaven and represent the norm of Sheng; the lower three Qi (Shaoyang, Yangming, Taiyang) are governed by Earth and represent the norm of Fu. Where there is Sheng, there is Fu; where there is no Sheng, there is no Fu. Sheng brings about Fu, but there is no fixed number; it stops when the excess declines. If Fu occurs after Sheng, and there is no further Fu, harm results, damaging life. If Fu causes self-disease, it means the Fu Qi occupies an improper position and is incompatible. Excessive Fu against Sheng leads to the Master Qi counter-acting it, causing reverse illness. This refers to situations like Two Fires being in the Fountain position but occupying the Water position, or Si Tian Metal occupying the Fire position; other Qi combinations differ. However, treating Qi excess involves controlling severity according to subtlety; treating Qi rebound involves harmonizing and balancing. Violent cases require draining excess and tonifying deficiency so Qi naturally balances. If Master and Guest Qi clash without Fu, it is due to the natural fluctuation of Yin and Yang.
Master excess is "Ni" (Reverse), Guest excess is "Cong" (Following), which is the way of Upper and Lower. In Si-Hai years, Jueyin Wind Wood governs the Upper (Si Tian): Guest excess causes tinnitus, dizziness, and severe cough; Master excess causes chest and hypochondriac pain, tongue stiffness, and speech difficulty. In Zi-Wu years, Shaoyin君Fire governs the Upper: Guest excess causes nasal congestion, sneezing, neck stiffness, shoulder/back heat, headache, shortness of breath, fever, deafness, eye closure, severe edema, bleeding, sores, cough, and wheezing; Master excess causes heart heat, irritability, severe hypochondriac pain, and fullness. In Chou-Wei years, Taiyin Damp Earth governs the Upper: Guest excess causes head/facial edema, breathing difficulty, and wheezing; Master excess causes chest/abdominal fullness and dizziness after eating. In Yin-Shen years, Shaoyang Ministerial Fire governs the Upper: Guest excess causes erysipelas rashes, carbuncles, vomiting, throat obstruction, headache, throat swelling, and internal spasms; Master excess causes chest fullness, cough with仰息 (breathing with raised chest), severe hemoptysis, and hand heat. In Mao-You years, Yangming Dry Metal governs the Upper: Metal occupies the Fire position; Fire qi ascends, leaving residual coolness internally, causing cough, epistaxis, throat blockage, chest/diaphragm heat, persistent cough with expulsion of "White Blood" (light red blood resembling flesh/lung), which is fatal. In Chen-Xu years, Taiyang Cold Water governs the Upper: Guest excess causes chest discomfort, clear nasal discharge, and cold-induced cough; Master excess causes ringing in the throat.
(In Quan / Lower Position) In Yin-Shen years, Jueyin Wind Wood is in Quan: Guest excess causes large joint stiffness (waist/spine), internal spasms/tightness, and external movement difficulty; Master excess causes bone/tendon trembling and periodic waist/abdominal pain. In Mao-You years, Shaoyin君Fire is in Quan (Fire above Water position, Water flows down, hence Guest excess logic applies; Ministerial Fire shares signs): Guest excess causes waist pain, pathology in buttocks/thighs/knees/calves/feet, dizziness/heat with soreness, edema, inability to stand long, and urinary changes; Master excess causes Jue Qi ascending, heart pain, fever, diaphragmatic discomfort, widespread bi-syndrome onset in hypochondrium, uncontrolled sweating, and four extremities cold. In Chen-Xu years, Taiyin Damp Earth is in Quan: Guest excess causes foot atrophy/heaviness, difficult urination, dampness invading lower Jiao leading to loose stools, edema, and diseases of hidden areas (genitals/anus); Master excess causes cold Qi reversing with fullness, inability to eat, and severe hernia. In Si-Hai years, Shaoyang Ministerial Fire is in Quan: Guest excess causes waist/abdominal pain, aversion to cold, severe white discharge/urine; Master excess causes heat rising to the Heart, heart pain, fever, regurgitation/vomiting. Shaoyin signs are similar. In Zi-Wu years, Yangming Dry Metal is in Quan: Guest excess causes clear Qi moving downward, lower abdominal hardness/fullness, and frequent diarrhea; Master excess causes heavy waist/abdominal pain, cold in lower abdomen, duck-like loose stools, cold Jue in intestines rising to chest, severe wheezing, and inability to stand long. In Chou-Wei years, Taiyang Cold Water is in Quan: Both Master and Guest are Water, causing internal cold residue, waist/buttock pain with limited flexion/extension, and pain in thighs/shins/feet/knees.
In treating Master-Guest excesses, suppress high and elevate low, tonify deficiency and drain excess, and adjust according to Qi similarities/differences. If Master and Guest Qi are compatible, treat by opposing the dominant Qi; if incompatible, follow the non-dominant Qi. Opposition treatment is the primary method. Guest Qi is Heaven's Six Qi moving above Master positions; Master Qi is Earth's Six Qi beneath Guest Qi. Guest Qi moves ceaselessly; each year, two Qi govern Heaven/Earth, and four Qi act as Left/Right Intermediary Qi, changing positions with Master Qi. Master Qi is static and fixed, always starting with Wood (1st), Fire (2nd), Ministerial Fire (3rd), Earth (4th), Metal (5th), and Water (6th). Among these Six Qi, each has Master-Guest excesses. The Canon mentions Heaven/Earth Master-Guest excesses primarily to illustrate Water and Fire positions; others can be inferred. Thus, the Canon states: For Wood position Master, drain with Sour, tonify with Acrid; for Fire position Master, drain with Sweet, tonify with Salty; for Earth position Master, drain with Bitter, tonify with Sweet; for Metal position Master, drain with Acrid, tonify with Sour; for Water position Master, drain with Salty, tonify with Bitter. For Jueyin Guest, tonify with Acrid, drain with Sour, relax with Sweet; for Shaoyin Guest, tonify with Salty, drain with Sweet, astringe with Sour; for Taiyin Guest, tonify with Sweet, drain with Bitter, relax with Sweet; for Shaoyang Guest, tonify with Salty, drain with Sweet, soften with Salty; for Yangming Guest, tonify with Sour, drain with Acrid, drain with Bitter; for Taiyang Guest, tonify with Bitter, drain with Salty, consolidate with Bitter, moisten with Acrid. Open interstices, promote fluid production, and circulate Qi. Adapting to Master-Guest excesses for tonification and drainage is the subtle Dao, which must be thoroughly understood.
