On the first day of Shaoyang (Taiyang) disease, the pathogen is in the Taiyang channel. Symptoms include pain in the head, neck, and occiput, as well as stiffness and rigidity in the lower back and spine.
Transmission from Taiyang to Yangming is called "sequential transmission" (Xunjing Zhuan). Transmission to Shaoyang is called "cross-channel transmission" (Yuejing Zhuan). Transmission to Taiyin is called "transmission due to erroneous purgation" (Wuxia Zhuan). Transmission to Shaoyin is called "exterior-to-interior transmission" (Biao Chuan Li). Transmission to Jueyin is called "sequential transmission reaching its limit" (Xunjing Dedu Zhuan).
On the second day, Yangming channel pathogens are fully established. Symptoms include body heat, eye pain, and nasal dryness. On the third day, Shaoyang channel pathogens cause chest and hypochondriac pain and deafness; these diseases reside in the exterior channels. Among the three Yang channels' meridians, only one may be affected. The pathogen has not yet entered the Zang organs to form excess patterns; this belongs to sweating indications (suitable for diaphoresis).
This is a general overview. Three-Yang diseases can also transmit to the Fu organs. If transmitted to the Fu organs, purgation is appropriate.
On the fourth day, extreme Yang transmits to Taiyin. Symptoms include abdominal fullness, throat dryness, and a pulse approaching deepness. On the fifth day, Shaoyin disease trends inward. Symptoms include dry mouth, dry tongue, and unrelenting thirst. On the sixth day, the disease follows the Jueyin channel. Symptoms include vexation, abdominal fullness, retraction of the scrotum, and severe, deep heat. Once the Three-Yin channels are diseased, purgation is generally indicated.
However, Three-Yin diseases can also remain in the channels. If remaining in the channels, diaphoresis and warming methods are appropriate.
If re-infected, it is difficult to resolve with purgation alone. How to identify "Lianggan" (simultaneous contraction of cold)? Taiyang disease connects with Shaoyin. Symptoms include headache, dry mouth, vexation, abdominal fullness, and thirst. This results from blocked Ying and Wei, causing internal organ heat.
Yangming disease combined with Taiyin disease presents with abdominal fullness, body heat, and loss of appetite. Delirium appears within two days. On the third day, Shaoyang combines with Jueyin. Symptoms include deafness, scrotal retraction, and cold limbs. Food and drink cannot be taken, and consciousness is lost. The five Zang organs are damaged, and the six Fu organs are closed. Ying and Wei circulation stagnates.
In such situations, careful consideration is required. Warming, emetic, diaphoretic, and purgative methods must be used cautiously. For cases not involving Lianggan transmission, Taiyang disease resolves on the seventh day. Thereafter, each day sees the resolution of one channel.
After the Six Channels recover, the organ pulses connect. By the twelfth day, major pathogens are eliminated. The patient's spirit becomes clear, and Qi and Blood stabilize. If infected by other pathogens leading to different diseases, the general treatment principle should follow that for "Huaizheng" (ruined/complicated patterns).
For the exterior aspect of an exterior pattern, strong diaphoresis is needed. For the interior aspect of an exterior pattern, purgation should be delayed. For the deep interior of an interior pattern, immediate purgation is required. For the superficial interior of an interior pattern, moistening and soaking methods are used. One must appropriately apply Yin-Yang pulse theory. Based on exterior-interior distinctions, do not attack recklessly.
Shaoyang symptoms must all be carefully distinguished. Pattern transmission involves only six types.
The three Yin and three Yang channels of the foot constitute the Six Channel patterns.
There are nine common patterns.
Outside the Six Channels, there are three additional patterns: Taiyang-Yangming, Zhengyang-Yangming, and Shaoyang-Yangming.
Yang corresponds to the Exterior; Yin corresponds to the Interior.
Exterior is Yang; Interior is Yin.
Transmission and Lianggan (Double Contraction).
"Transmission" refers to sequential channel progression. "Variation" refers to non-sequential progression resulting in different patterns. When both Yin and Yang channels are diseased, it is called Lianggan or Shuangchuan, meaning simultaneous exterior and interior patterns.
Disease Ruination and Anomalies.
Some become "Huaizheng" (ruined patterns) due to treatment errors. Some have corresponding signs but suddenly change after taking medicine; this is called a "Zaiguai" (disaster anomaly).
Hebing (Combined Disease) and Bingbing (Concurrent Disease).
Two Yang channels diseased simultaneously is Hebing. If two Yang channels were initially diseased together, and later one remains diseased independently, it is Bingbing.
One Disease, Hundred Connections.
Diseases have beginnings and endings. If only one channel is involved, such as when all vessels from one source are diseased, it is called Baihebing (Lily Disease).
Differentiating Wind, Summerheat, Dampness, Warmth, and Spasm.
These six patterns differ from Shaoyang.
Cold is originally a Yin pathogen. It becomes hot through stagnation, becoming fierce and transferring heat to the Hand channels ("Yuanre").
Shaoyang affects only the Foot channels. Conditions like constipation, irritability, asthma, petechiae, and epistaxis are diseases of Yuanre affecting the Hand channels. As Shouzhen (Liu Wansu) stated: Yang pathogens affect Hand channels; Yin pathogens affect Foot channels.
Exterior-Interior Deficiency-Excess.
Refers to Exterior Deficiency with Interior Excess, or Exterior Excess with Interior Deficiency.
Exterior-Interior Cold-Heat.
Includes Exterior Cold with Interior Heat, or Exterior Heat with Interior Cold.
Water Retention in Exterior-Interior.
Water in the Exterior often causes heat, cough, or diarrhea. Water in the Interior causes hypochondriac stuffiness or hardness, cool body, sweating, and hypochondriac pain.

Includes Cold Jue and Heat Jue patterns.
Yang Patterns and Yang Du (Poison).
Exclusive excess of the Three Yang channels; sudden collapse of Yin deficiency.

Yang Patterns Resembling Yin.
Yin-like symptoms appear, but the pulse is deep, slippery, and forceful.
Yin Patterns Resembling Yang.
Yang-like symptoms appear, but the pulse is deep and faint.
Yang Excess Rejecting Yin, Yin Excess Repelling Yang, Yin-Yang Imbalance, Yang Knotting, Yin Knotting.
Yang-heat pathogens knot internally; Yin Qi cannot mix. Symptoms include ability to eat but constipation. This is Internal Excess, named Yang Jie (Yang Knot).
Yin-cold pathogens knot internally; Yang Qi cannot mix. Symptoms include inability to eat, heavy body, and hard stool. This is named Yin Jie (Yin Knot).
Yin Yi and Yang Yi.
If a man newly recovered from illness has intercourse with a woman, the disease transfers to her, called Yang Yi. If a woman newly recovered has intercourse with a man, the disease transfers to him, called Yin Yi.
Fever and Tide Fever.
Heat comes and goes irregularly, or occurs at dusk (Shen hour), is called Tide Fever (Chao Re).
Aversion to Wind and Aversion to Cold.
Wind injury causes aversion to wind. Aversion to cold with fever indicates Yang disease. Only aversion to cold indicates Yin disease. Aversion to cold after sweating indicates Exterior Deficiency.
Alternating Chills and Fever.
Chills or fever occur at regular intervals.
Heat Remaining After Sweating.
Fever returns after sweating, usually due to Internal Excess or residual heat in other channels.
Heat Remaining After Purgation.
Due to unresolved Exterior patterns, or recurrence of heat due to weak Yin.
Jie Xiong (Chest Binding) and Pi (Glomus).
Pain upon pressing the epigastrium is Xiao Jie Xiong (Minor Chest Binding). Spontaneous pain without pressing is Da Jie Xiong (Major Chest Binding). No pain upon pressing, with qi knotting or fullness in the chest, is Pi (Glomus).
Zang Jie (Organ Binding) and Hui Jue (Roundworm Reversal).
Constipation indicates Zang Jie. Cold deficiency in the stomach leads to Hui Jue, characterized by vomiting roundworms.
Jaundice and Mania.
Jaundice from blood stasis results from Taiyang transmitting to its home. Jaundice from Jie Xiong results from premature purgation, belonging to Taiyang-Yangming. Damp-heat jaundice belongs to Yangming-Taiyin. Cold-damp jaundice belongs to Shaoyang-Taiyin. Liver heat causes mania; Heart heat causes insanity.
Erythema and Urticaria.
Caused by premature purgation, failure to purge, or extreme Stomach heat. These result from Yangming heat entering the Hand Taiyin Lung channel. Erythema presents as red spots with halos; urticaria presents as raised bumps.
Asthma and Cough with Reverse Flow.
Qi reversal causes asthma and difficulty breathing. Failure to purge interior disease causes cough with reverse flow.
Epistaxis Indications.
Nosebleed is Epistaxis. Heat knotting in the Lower Jiao causes blood stasis and hemorrhage indications.
Spitting Pus and Hemoptysis.
Severe fluid depletion with heat in the Upper Jiao causes Lung萎 (Flaccidity) with spitting of pus and blood.
Delirium and Soft Speech.
Excess patterns cause delirium; deficiency patterns cause soft speech (Zheng Sheng).
Vexation, Irritability, and Thirst.
Fire entering the Lung causes vexation; fire entering the Kidney causes irritability. Shaoyin patterns often involve thirst and coughing up water. All Six Channels can present with thirst.
Internal Vexation (Ao Nao).
Restlessness, turning over repeatedly, mental confusion as if losing something.
Palpitations in the Heart Region.
Trembling chills and movement indicate palpitations, also called Zheng Zhong.
Qi Rushing to the Chest.

Dry Heaving and Vomiting.
Dry heaving is Gan Ou. Vomiting immediately after eating is Tu Ni.
Abdominal, Hypochondriac, and Throat Pain.
Includes intermittent abdominal pain, hypochondriac pain, and dry/painful throat.
Rejection Pain in the Diaphragm.
Unresolved Exterior combined with Stomach deficiency allowing pathogens to knot internally causes pain.
Body Aches and Heaviness.
Poor Ying-Blood circulation causes aches; dampness excess causes heaviness. Aches after sweating indicate residual pathogens.
Cough and Saliva Excess.
Fire attacking the Lung causes cough; retained water from wind-cold-damp causes cough. Spleen heat causes saliva excess.
Head Sweat and Spontaneous Sweat.
Interior deficiency with Exterior excess causes Yang Qi to rise, leading to sweat on the head, possibly stopping at the neck, indicating jaundice. Spontaneous sweat occurs in Wind Injury, Wind-Warmth, Wind-Damp, Summerheat, Rou Jing, Huoluan, Diarrhea, Cold Limbs, and Yangming patterns.
Leaking Sweat Unstoppable.
Insufficient Yang Qi, worsened by sweating, leads to insecure skin pores and unstoppable sweat.
Yang Restlessness with No Sweat.
Extreme Yang causes restlessness and heat without sweat.
Abdominal Fullness and Urinary Incontinence.
Qi stagnation causes abdominal fullness. Lower Jiao failure to control leads to urinary incontinence.
Slippery Tongue Coating.
Heat in the Dan Tian (Lower Jiao) with Cold in the Stomach (Middle Jiao).
Diarrhea and Hematochezia.
Diarrhea is Xia Li or Sun Xie. Lower Jiao lack of restraint with severe heat causes hematochezia.

Always Remember This: Shaoyang Ruination and Anomalies. Observe Pulse and Patterns, Transmission, Variation, Relapse, and Reversal.
"Transmission" is regular channel progression. "Variation" is irregular, e.g., Yang suddenly changing to Yin. "Relapse" includes Food and Labor relapse. "Reversal" means failure to resolve after sweating, vomiting, or purgation, constituting a medical error. For such ruined patterns, refer to Xu Shumi's *Shaoyang Hundred Patterns Song* for classification; study it thoroughly.
Carefully master Yin-Yang, treat according to patterns, and apply appropriate methods.
Shaoyang transmission is irregular; carefully distinguish Yin-Yang patterns and apply suitable treatments. Methods include sweating, harmonizing, purging, moistening, emesis, fire therapy, moxibustion, water therapy, acupuncture, and warming.
[Image ps16a5.bmp]
Sweating is for Exterior patterns. Harmonizing is for disharmonious Ying-Wei. Purging is for Interior patterns. Moistening is for Yin Dryness. Emesis is for food stuck in the Upper Wan. Fire therapy is for Yin Du patterns. Moxibustion is for sinking Yin patterns. Water therapy is for Heat with Dryness. Acupuncture is for Concurrent Diseases. Warming is for Interior Cold.
Detail what is contraindicated, study the *Shaoyang Lun*, understand disease mechanisms, and learn treatment examples. Strive to keep them secret and recite them without weariness.
