(Twelve pulse and syndrome patterns, five prescriptions)
The pulse at the Cun Kou (radial artery) is agitated and weak. Agitation indicates fright; weakness indicates palpitations.
[Commentary] The Heart is the sovereign official, from which the Shen (Spirit) emerges. If one does not overexert the body or labor the mind, then Jing Qi (Essence and Qi) will be abundant, and the Shen will dwell securely in its residence. If injured, Qi deficiency leads to an agitated pulse; agitation causes palpitations and mental fear. Essence deficiency leads to a weak pulse; weakness causes Zheng Chong (palpitations with anxiety) and fearful trembling. Generally, Fright arises from external stimuli touching the heart, belonging to Yang; Yang transformation leads to an agitated pulse. Palpitations arise from internal fear, belonging to Yin; Yin consumption leads to a weak pulse. Therefore, this disease is suitable for mild agents to tonify Essence and Qi, and to anchor the Spirit. It is especially important to manage it with tranquility.
The Master said: A floating pulse at the Chi position, with yellow halos around the eyes, indicates that epistaxis has not stopped. When the yellow halos disappear and the eyes become clear and bright, one knows that the epistaxis has now stopped.
[Commentary] The Chi pulse assesses the Kidney, which belongs to Water. Earth controls Water; if Xiang Huo (Ministerial Fire) combines with pathogenic factors, it forces Yin Blood to ascend from the Bladder, hence the floating pulse. The Kidney's essence ascends to nourish the pupils. The Bladder meridian ascends to the forehead and causes epistaxis. Thus, when the yellow halo recedes, blood also descends, indicating that epistaxis has stopped. *Ming Li Lun* states that the Kidney governs Yin, and Blood is subordinate to it. In Shang Han (Cold Damage) diseases, epistaxis is attributed to pathogens in the Exterior, where excessive heat in the meridians causes bleeding. In miscellaneous diseases, epistaxis is attributed to pathogens in the Interior. The Heart governs Blood, the Liver stores Blood, the Lung governs Qi and opens into the nose. When Blood is heated, it scatters and reverses upward with Qi, exiting through the nose, which is called Ni. Here, the Chi pulse is floating, not the Cun Kou, indicating Kidney deficiency with reversed Blood, not an external pathogen.
It is also said: From Spring to Summer, epistaxis belongs to the Tai Yang (Greater Yang) channel; from Autumn to Winter, epistaxis belongs to the Yang Ming (Bright Yang) channel.
[Commentary] The *Nei Jing* states that Tai Yang is "Opening" and Yang Ming is "Closing." In Spring and Summer, Qi governs growth and generation, responding to "Opening," so pathogens force Blood to surge outward. In Autumn and Winter, Qi governs storage and consolidation, responding to "Closing," so pathogens are deeply郁 (stagnant) internally before emerging. Epistaxis indicates excess Yang. Shaoyang (Lesser Yang) is not mentioned because both Tai Yang and Yang Ming meridians intersect at the forehead.
Individuals prone to epistaxis should not undergo sweating therapy. If sweating occurs, there will be depression of the forehead, an urgent/tight pulse, staring fixedly without blinking, and inability to sleep.
[Commentary] Foot Tai Yang governs the Exterior, ascending to the vertex, entering the forehead, and passing through the eyes. Epistaxis occurs in the upper part, where collateral Blood has already been lost. Further sweating would further deplete Body Fluids. Depleted fluids lead to dry pulses, causing forehead depression and urgent pulses that pull the eyes, resulting in inability to close them. Lack of Blood and Yin deficiency cause insomnia. However, there are cases where sweating is indicated. *Shang Han Lun* states: With a floating-tight pulse, if sweating is not induced leading to epistaxis, Ma Huang Tang (Ephedra Decoction) is appropriate. It also states: In Tai Yang disease, with a floating-tight pulse, fever, no sweat, spontaneous epistaxis leads to recovery. Pathogens in the channels disperse without needing Gui Zhi Tang (Cinnamon Twig Decoction) or Ma Huang Tang. *Ming Li Lun* states that those with epistaxis who only have head sweat, or no sweat/sweat not reaching the feet, will die.
Patients with a pale complexion, no aversion to cold or fever, and a deep-wiry pulse suffer from epistaxis. Those with a floating-weak pulse that disappears upon pressure suffer from lower bleeding. Those with irritability and coughing will certainly vomit blood.
[Commentary] Complexion is the bloom of Blood. Abundant Blood yields a fresh luster. Cold/Heat damages Blood, causing pallor. Without cold/heat, bleeding from above or below is the cause. Floating pulses assess Yang; deep pulses assess Yin. Only deep-wiry pulses, disappearing on light touch, indicate absence of Yang, implying upper Blood loss. Only floating-weak pulses, disappearing on heavy pressure, indicate absence of Yin, implying lower Blood loss. Irritability, coughing, and hematemesis occur because the Heart relies on Blood to calm the Shen. Heat disturbs, causing Blood surging and Shen agitation. Upward disturbance to the Diaphragm causes coughing, forcing Blood upward. Deep pulses lacking floating qualities, and floating pulses lacking deep qualities, indicate Blood loss because the complexion is colorless and pulses are wiry/weak. Although Yang escapes in epistaxis, Yin is also damaged, making the pulse weak even on light touch. Classics state: Weakness indicates Blood deficiency. The Pulse is the mansion of Blood; thus, at sites of Blood loss, the pulse may be absent, or wiry/weak where Blood is damaged.
For hematemesis accompanied by rebellious Qi and coughing, rapid pulse, fever, and inability to lie down, the prognosis is fatal.
[Commentary] This is due to insufficiency of the Metal (Lung) and Water (Kidney) organs. External insufficiency leads to floating Fire flames, damaging Lung Metal. Internal Yin Blood is nurtured by Kidney Water. Water deficiency fails to provide tranquility, allowing Fire to force Blood outflow. Blood loss intensifies Yang/Sun, creating ascent without descent, scorching Lung Metal. Metal damage causes rebellious Qi and coughing. Metal and Water are mother-child; child decline cannot save the mother, and mother decline cannot generate the child. Both Yins are exhausted without recovery. Rapid pulse and fever indicate Yang excess. Inability to lie down indicates Yin exhaustion. If Yin is exhausted, can Yang survive alone? Hence, death. If able to lie down, as in *Nei Jing* discussions on Si Tian and Yang Ming reversal with wheezing, cough, fever, vomiting, and blood, death is not predicted because Yin is not exhausted.
Alcoholics who cough will certainly vomit blood, caused by excessive drinking.
[Commentary] Wine is too hot. If retained, it clouds Liver Qi and destabilizes Stomach Qi, chaotic in the chest. Middle Jiao Blood fails to distribute to meridians, gathering turbulently. Heat shoots into the Lung causing cough, expelling Blood via rebellious Qi. This is Stomach injury causing hematemesis.
The pulse at Cun Kou is wiry and large. Wiry indicates reduction; large indicates hollow (Kou). Reduction indicates Cold; hollow indicates Deficiency. Cold and Deficiency striking each other is named Ge (Leather) pulse. In women, it indicates miscarriage and dripping bleeding; in men, it indicates loss of Blood.
[Commentary] Cheng Wuji states "reduction is Cold" means little Yang Qi; "hollow is Deficiency" means little Yin Blood. Ge pulse, being both Cold and Deficient, leads to Qi deficiency and Blood deviation, failing to follow normal pathways. In men, true Yang declines and cannot secure internally, causing Blood loss. In women, Yin Blood is deficient and cannot nourish, causing miscarriage and dripping bleeding. This item appears in Volume 2 on Women's Diseases, mentioning Xuan Fu Hua Tang (Inula Flower Decoction).
Those with Blood loss should not be treated with exterior-releasing methods. Sweating will cause chills and tremors.
[Commentary] Blood loss injures Ying (Nutritive) Qi; one must not sweat to injure Wei (Defensive) Qi. Sweating injures both Ying and Wei. Ying moves within vessels; Wei moves outside. Ying deficiency empties vessels, causing tremors. Wei deficiency fails to warm pores, causing chills.
[Supplementary Note] *Shang Han Lun* says Blood loss is Yin loss. Yin loss leaves Yang solitary and unpaired. Upon sweating, Yang escapes completely with sweat, worsening chills, indicating dual exhaustion of Yin and Yang. The general method suggests Xiao Jian Zhong Tang (Minor Construct the Middle Decoction).
Patients with chest fullness, withered lips, cyan tongue, dry mouth desiring to rinse but not swallow, no cold/heat, micro-large slow pulse, abdominal non-distension but subjective chest fullness, have Blood stasis.
[Commentary] This syndrome is Blood stasis. What pathogen causes it? *Nei Jing* mentions falling/fear causing evil Blood retention, abdominal distension, and bowel/bladder obstruction. Great anger causes Blood stagnation upward. Thus, any internal/external pathogen clumping and stagnating constitutes Blood stasis. Lips reflect Spleen; tongue reflects Heart. Spleen meridian spreads under tongue; Stomach meridian circles mouth. Heart governs Blood; Spleen nourishes Blood. Stagnation prevents fluid distribution, causing withered lips and cyan tongue. Dry mouth desiring rinse but not swallow indicates heat is not internal, so rinsing moistens. Large pulse indicates Heat; slow indicates Cold. No cold/heat symptoms but micro-large pulse indicates Qi merging upward, causing chest fullness. Slow pulse indicates Blood accumulation below the diaphragm. Accumulation in Yin channels' tunnels differs from Qi accumulation in Yang blind membranes. Yang paths are manifest; Yin paths are hidden. Qi in blind membranes causes visible distension; Blood in tunnels causes only blockage, so abdomen is not distended, though patient feels full. Thus, it is known to be Blood stasis.
Patient resembles heat syndrome: irritability, fullness, dry mouth/thirst, but pulse lacks heat signs. This is Yin伏 (hidden/stagnant), indicating Blood stasis. Purge it.
[Commentary] Blood is Yin, paired with Yang. Shen rests on it, Qi harmonizes with it, throat moistens with it, meridians flow with it. It is inseparable from the body. Now, due to Blood stasis, Shen lacks nourishment (irritability), Qi lacks harmony (fullness), mouth lacks moisture (dryness), intestines/stomach lack lubrication (thirst). These result from Yang losing its pairing, Ying/Wei not moving, fluids not transforming. This is not Yang generating heat itself, hence "resembling heat."
Caused by Fire Pathogen: Treat with Gui Zhi Qu Shao Yao Jia Shu Ku Mu Li Long Gu Jiu Ni Tang (Cinnamon Twig Decoction minus Peony plus Chinese Tussilaginea Herb, Oyster Shell, and Dragon Bone to Rescue Deviation).
Gui Zhi Qu Shao Yao Jia Shu Ku Mu Li Long Gu Jiu Ni Tang Formula
Gui Zhi (Cortex Cinnamomi, peeled, 3 liang) Gan Cao (Radix Glycyrrhizae, honey-fried, 2 liang) Sheng Jiang (Rhizoma Zingiberis Recens, 3 liang) Shu Ku (Herba Thlaspidis, washed to remove fishy odor, 3 liang)
Long Gu (Os Draconis, calcined, 4 liang) Mu Li (Concha Ostreae, calcined, 5 liang) Da Zao (Fructus Jujubae, 12 pieces)
[Commentary] This mentions only Fire Pathogen, not specific symptoms. Examining it reveals Shang Han with floating pulse, treated by doctor with fire methods causing Yang collapse, leading to fright, mania, restlessness. Cheng Wuji notes: Sweat is Heart fluid. Yang collapse causes Heart Qi deficiency. Heart dislikes Heat; internal pathogenic pressure causes Shen floating, leading to fright/mania/restlessness. Gui Zhi Tang resolves residual exterior pathogens. Shao Yao nourishes Yin, unsuitable for Yang collapse, so removed. Fire pathogen rebellion requires Shu Ku's acridity to dissipate. Yang collapse requires Long Gu/Mu Li's astringency to secure.
Palpitations below the heart: Treat with Ban Xia Ma Huang Wan (Pinellia and Ephedra Pill).
Ban Xia Ma Huang Wan Formula
Ban Xia (Rhizoma Pinelliae) Ma Huang (Herba Ephedrae)
Grind these two into powder, mix with refined honey to form pills the size of small beans. Take three pills with water, three times daily.
[Commentary] Palpitations are the heart's fluttering sensation, Zheng Chong (palpitations with anxiety). There are three types: Shang Han with Zheng Qi (Upright Qi) deficiency; post-sweating/purging with internal Zheng Qi deficiency and pathogenic clash. Different pathogens require different treatments. Zheng Qi deficiency uses Xiao Jian Zhong Tang or Si Ni San plus Gui Zhi. Excessive water intake causing palpitations: Heart is Fire and dislikes Water, feeling uneasy. Post-sweating/purging deficiency with pathogenic clash is worse than Qi deficiency; treatment requires anchoring/securing or resolving/dispersing, stabilizing floating Qi. *Yuan Bing Shi* states this disease belongs to Water deficiency and Heat prosperity, Wind/Fire/Dryness moving internally, causing Zheng Chong. Fright/Palpitations also result from Fire drugs injuring Metal, failing to pacify Wood, Wind/Fire clashing. Investigating palpitation pathogens is complex. It may arise from cold exposure or cold drinks. Heart governs pulses; Cold injures Ying, impeding pulses. Cold drinks cause Water retention, blocking Middle Qi, impeding pulses, causing Heart Fire depression and movement. Ma Huang disperses Ying Cold; Ban Xia disperses Heart Water. The first chapter links weak pulses to palpitations, but this formula is used when pulses are not weak, likely wiry or tight. Would weak Qi deficiency allow such herbs?
Unceasing hematemesis: Treat with Bai Ye Tang (Cupressus Leaf Decoction).
Bai Ye Tang Formula
Bai Ye (Folium Cupressi) Gan Jiang (Rhizoma Zingiberis Secatum, 3 liang each) Ai Ye (Folium Artemisiae Argyi, 3 bundles)
Boil these three in 5 sheng of water, add 1 sheng of Ma Tong Zhi (Horse dung juice), decoct to 1 sheng. Divide into two warm doses.
[Commentary] Water sinks in cold, rises in wind. Human Blood is similar. Mild cold keeps Blood in meridians, nourishing organs. Severe cold coagulates Blood, preventing flow. Mild heat circulates Blood, filling orifices. Severe heat creates wild winds/fire, causing turbulent waves. Thus, hematemesis/epistaxis results from Wind/Fire.
Lower bleeding with stool before blood is distant bleeding (Yuan Xue): Treat with Huang Tu Tang (Yellow Earth Decoction).
Huang Tu Tang Formula
Gan Di Huang (Radix Rehmanniae Preparata) Huang Qin (Radix Scutellariae) Fu Zi (Radix Aconiti Lateralis Preparata, 1 liang) E Jiao (Colla Corii Asini) Bai Zhu (Rhizoma Atractylodis Macrocephalae) Gan Cao (Radix Glycyrrhizae, 3 liang each) Zao Xia Huang Tu (Caulis Fictorici, 0.5 jin)
Decoct these seven in 8 sheng of water to 3 sheng. Divide into three warm doses.
[Commentary] Intestines/Stomach are Yang Ming channels. Yang Ming governs closing; Qi naturally converges. Upward Blood flow is rebellious; downward is smooth. Regarding lower bleeding: Stomach is above Large Intestine. If Blood gathers in Stomach, stool precedes blood, far from anus, hence "distant bleeding." If in Large Intestine, near anus, hence "near bleeding." Though same channel, Stomach is Earth (governs reception/transformation, likes warmth/dislikes dampness); Large Intestine is Metal (governs transmission, likes cold/dislikes heat). Differences include distance and preferences. Huang Tu Tang treats distant bleeding. Why Blood in Stomach? Blood transforms in Middle Jiao, ascends to Ying to pair with Wei. Ying/Wei changes rely on Stomach Earth. Stomach/Spleen are interior-exterior. Stomach deficiency fails to move Qi to Three Yang; Spleen deficiency fails to move fluids to Three Yin. Qi declines, pulses obstruct, Blood accumulates and rebels, causing vomiting/epistaxis/diarrhea. To support Earth, use Yellow Earth. Yellow is Earth's true color; fired, it becomes Mother of Earth, dry not damp. Warmth transforms Blood, dissolving accumulation, stopping overflow. E Jiao benefits Blood (cow is Earth animal, symbolic). Di Huang nourishes Blood (symbolic). Gan Cao/Bai Zhu nourish Blood/Stomach (flavor similarity). Gan Cao moderates Fu Zi's heat. This formula treats distant bleeding and chronic hematemesis with weak/slow pulses. Stomach Yang failure requires Fu Zi's mobility to open meridians and disperse stasis. Spleen Yin disorder requires Huang Qin's bitterness to solidify Yin and secure Blood. Huang Qin also moderates Huang Tu/Fu Zi heat, acting as envoy.
Lower bleeding with blood before stool is near bleeding (Jin Xue): Treat with Chi Xiao Dou Dang Gui San (Adzuki Bean and Angelica Powder).
[Commentary] Originates from Large Intestine, hence blood before stool. Damp-Heat toxin accumulates, infiltrating intestines. Chi Xiao Dou moves Damp-Heat, resolves toxins. Mei Shi Fang uses this alone for lower bleeding. Dang Gui breaks old Blood, nourishes new. Symbolically, Blood returns to its source, ceasing erratic flow.
Heart Qi insufficiency with hematemesis/epistaxis: Treat with Xie Xin Tang (Drain the Epigastrium Decoction).
Xie Xin Tang Formula
Huang Lian (Rhizoma Coptidis) Huang Qin (Radix Scutellariae, 1 liang each) Da Huang (Radix et Rhizoma Rhei, 2 liang)
Decoct these three in 3 sheng of water to 1 sheng. Take all at once.
[Commentary] Heart is Fire, governs Blood. "Heart Qi insufficiency" refers not to Heart Fire deficiency, but True Yang deficiency. True Yang deficiency leads to excess Heat, preventing Heart from nourishing Blood, causing Heat-driven hemorrhage. Huang Lian/Huang Qin treat Blood closure/hemorrhage in Materia Medica. Shang Han practitioners use Xie Xin Tang's bitter-cold nature to drain Epigastric Fullness-Heat. Thus, this syndrome involves Heart Heat driving Blood out; draining Heart Heat calms Blood. Ma Huang/Gui Zhi treat epistaxis from Cold constraint transforming to Heat; dispersing Cold resolves Heat, calming Blood. Xie Xin Tang addresses this directly. Ji Zhong Fang uses Da Huang + Sheng Di汁 for epistaxis to cool Blood, similar to Xie Xin Tang.
