All six diseases have wind, each with its own exterior medicine.For Taiyang disease, the primary exterior medicine is Ma Huang (Ephedra).For Yangming disease, the primary exterior medicine is Shi Gao (Gypsum).For Shaoyang disease, the primary exterior medicine is Chai Hu (Bupleurum).For Shaoyin disease, the primary exterior medicine is Gui Zhi (Cinnamon Twig).For Jueyin disease, the primary exterior medicine is Qian Hu (Peucedanum).(Pure exterior/interior diseases are easy to distinguish and resolve.)(First distinguish between exterior and interior, especially emphasize exterior symptoms.)Ma HuangTaste and properties: Bitter—can drain (drain internal water and blood stasis), pungent can disperse (disperse exterior fluids/blood stagnation), pungent and warm—disperse exterior Wind Cold.Effects of Ma Huang: Releases the exterior, expels pathogens, promotes the flow of water, disperses blood stasis, awakens the mind and opens the orifices.According to the Shen Nong Ben Cao Jing, it is bitter and warm. It is indicated for wind-cold headache, warm malaria, releases the exterior, induces sweating, expels evil heat, stops cough and counterflow qi, eliminates cold and heat, breaks up masses and accumulations. Ma Huang is used to eliminate evil blood cases such as plasmacytic mastitis swelling, abscesses, and evil blood.Taiyang disease is an exterior heat syndrome, hence Ma Huang is used to disperse it.1. In Taiyang disease, the pulse is floating.3. In Taiyang disease, whether there is fever or not, there must be aversion to cold, body aches, vomiting, and a pulse that is tight in both yin and yang, this is called cold damage.51. A floating pulse indicates the disease is in the exterior, sweating can be induced, and Ma Huang Tang (Ma Huang Decoction) is appropriate.52. A floating and rapid pulse indicates sweating can be induced, and Ma Huang Tang is appropriate.35. In Taiyang disease, headache, fever, body pain, low back pain, joint pain, and aversion to wind are symptoms of exterior heat—Ma Huang Tang syndrome (regardless of whether the pulse is rapid or slow).Aversion to cold—defensive qi perceives excessively.Wheezing—upper jiao is urgent and suffering—exterior syndrome.Taiyang disease is an exterior heat syndrome caused by the body’s exposure to wind, cold, and other external pathogens, leading to a group of symptoms due to the defensive qi’s efforts to expel the pathogens. Therefore, it should be released from the exterior.The application of Ma Huang as the primary exterior medicine in classical formulas.Releasing the exterior and expelling pathogens to treat cold, heat, cough, wheezing, and wind-cold exterior diseases.Promoting the flow of water to treat water syndrome, dampness, and jaundice (Ma Huang Jia Zhu Tang).Dispersing blood stasis to treat blood stasis, vomiting, epistaxis, and evil blood (Ma Huang Tang, Wai Tai Shen Shi Ma Huang Tang).Awakening the mind and opening the orifices to treat sudden death, adverse reactions to wind, and stroke.Contraindications for Ma Huang’s application.Ma Huang promotes its yang.Here, “yang” does not refer to the “yang qi” relative to yin blood, but refers to fluids and blood.As in “if a person has blood deficiency, Ma Huang promotes its yang.”Shi GaoTaste and properties: Pungent and cold, pungent—releases the exterior, cold—clears heat.Effects: Releases the muscles and induces sweating, clears evil heat, eliminates water.According to the Shen Nong Ben Cao Jing: it is pungent and slightly cold. It is indicated for wind-cold heat, counterflow qi in the heart, dry mouth, bitter taste, inability to breathe, abdominal pain, expels evil spirits, promotes lactation, and treats traumatic injuries.(Gui Zhi represents the yang method—releasing the exterior and inducing sweating—wind-cold cold.)The yin method—releasing the muscles and inducing sweating—protecting fluids—wind-heat cold.) The Qian Jin Wai Tai and other texts extensively discuss the muscle-releasing method, one yin and one yang.It can be found that the yin method—muscle-releasing method.The yin method—Shao Yao (Peony) and Gan Cao (Licorice) Decoction is a muscle-releasing method that protects fluids.1. The Shi Gao method clears real heat and releases the muscles.2. The Shao Yao method clears false heat and releases the muscles.3. The Ge Gen method addresses both real and false (Jin Gui Yao Lue for spasms).Yangming disease, the method often induces sweating. It is characterized by heat steaming. The representation of fire heat steaming—pungent and cold induces sweating and expels pathogens externally, clears evil heat.Shi Gao eliminates water—wind water, excess fluid—Yue Bi Tang (Yue Bi Decoction).Pungent, cold, and bitter descend from the pores and from the lower orifices—diarrhea.Yangming disease is a real heat syndrome in the interior, hence the exterior of Yangming requires Shi Gao to clear and resolve.In the Shang Han Lun 168: Cold damage, whether vomiting or purging, if after seven or eight days it does not resolve, heat is bound in the interior, both exterior and interior are hot, there is often aversion to wind, great thirst, dry tongue, and irritability, desiring to drink several sheng of water, Bai Hu Jia Ren Shen Tang (White Tiger Decoction with Ginseng) is indicated.Releasing the muscles: Shi Gao releases exterior wind-cold-dampness.In the Jin Gui Yao Lue, Taiyang with internal heat is a fever. Sweating leads to aversion to cold, body heat, and thirst, Bai Hu Jia Ren Shen Tang is indicated.Clearing evil heat: In the Shang Han Lun 219: Three Yang combined disease, abdominal fullness, heavy body, difficulty turning, numbness of the mouth, facial dirt, delirium, and incontinence. Sweating leads to delirium, purging leads to sweating on the forehead, and cold in the hands and feet. If there is spontaneous sweating, Bai Hu Tang (White Tiger Decoction) is indicated.350: Cold damage, if the pulse is slippery and there is cold extremities, there is heat in the interior, Bai Hu Tang is indicated.Gui Zhi Decoction is contraindicated for facial symptoms (freshly ground wheat flour—pungent and dispersing).Shi Gao’s contraindications: In cases of interior deficiency and cold, it is not suitable to use Shi Gao.280: Taiyin disease, the pulse is weak, and the person continues to have frequent bowel movements, if large doses of Da Huang and Shao Yao are to be used, it should be reduced, as the person’s stomach qi is weak and easily disturbed. If there is diarrhea, first decoct Shao Yao three times.In the Ben Jing, abdominal pain.In the Bie Lu, heat in the intestines and stomach.Chai HuTaste and properties:Bitter—drains, slightly pungent—can disperse, opens and clears heat, neutral (slightly cold)—neutral is close to cool.In large doses, Chai Hu ascends and disperses (in Xiao Chai Hu Tang (Minor Bupleurum Decoction)).In small doses, it clears constrained heat (in Si Ni San (Four Counterflow Powder)).Shaoyang disease is half exterior and half interior, half cold and half heat, leaning towards yang, requiring Chai Hu to disperse half exterior, half heat, and half real heat.96: In cold damage for five or six days, wind-cold, alternating between cold and heat, fullness in the chest and ribs, silent and unwilling to eat, irritability with a preference for vomiting, or fullness in the chest without vomiting, or thirst, or abdominal pain, or hardness under the ribs, or palpitations, or difficulty urinating, or no thirst, slight fever, or cough, Xiao Chai Hu Tang is indicated.97: Blood weak and qi exhausted, pores open, evil qi enters and clashes with the righteous qi, binding under the ribs, righteous and evil contend, alternating between cold and heat, resting at times, silent and unwilling to eat. The pain in the chest and ribs must descend, the evil is high and causes pain below, hence it leads to vomiting. Xiao Chai Hu Tang is indicated.Chai Hu paired with other herbs achieves different effects.Chai Hu paired with Huang Qin: clears half exterior, half interior, and half real heat.266: In cases of Taiyang disease, if it does not resolve and transitions to Shaoyang, there is hardness and fullness under the ribs, dry vomiting, inability to eat, alternating between cold and heat, not yet vomiting or purging, and the pulse is wiry and tight, Xiao Chai Hu Tang is indicated.Women with wind-cold, continuing for seven or eight days, with intermittent attacks, menstruation just stopped, this is heat entering the blood chamber. The blood must be congealed, hence it appears like malaria, with intermittent attacks, Xiao Chai Hu Tang is indicated.Chai Hu paired with Gui Zhi: treats Shaoyang wind-cold leaning towards the exterior position with congealed fluids and blood.146: In cold damage for six or seven days, fever, slight aversion to cold, joint pain, slight vomiting, fullness under the heart, and the exterior symptoms have not resolved, Chai Hu Gui Zhi Tang (Chai Hu and Cinnamon Twig Decoction) is indicated.147: In cold damage for five or six days, after sweating and then purging, fullness in the chest and ribs, slight hardness, difficulty urinating, thirst without vomiting, but sweating on the head, alternating between cold and heat, irritability, this is unresolved, Chai Hu Gui Zhi Gan Jiang Tang (Chai Hu, Gui Zhi, and Ginger Decoction) is indicated.Chai Hu paired with Da Huang: clears Shaoyang, leaning towards the interior, with congealed fluids and heat.103: In Taiyang disease, after more than ten days, if there are two or three purges, and after four or five days, if the Chai Hu syndrome still exists, first use Xiao Chai Hu Tang. If vomiting does not stop, and there is urgency under the heart, irritability, slight annoyance, this is unresolved, and Da Chai Hu Tang (Major Bupleurum Decoction) is indicated; if there is fullness and pain under the heart, this is real, it should be purged, Da Chai Hu Tang is indicated.Chai Hu’s contraindications: Chai Hu eliminates fire binding, heavy water binding should not be used.149: In cold damage for five or six days, if there is vomiting and fever, the symptoms of Chai Hu are present, and if other herbs are used to purge, and the Chai Hu symptoms still exist, using Chai Hu Tang again, although it has been purged, it does not reverse, it must be steaming and rising, leading to fever, sweating, and resolution; if there is fullness under the heart and pain, this is a binding chest, Da Xian Xiong Tang (Major Chest-Resolving Decoction) is indicated; but if it is fullness without pain, this is a distension, Chai Hu should not be used, Ban Xia Xie Xin Tang (Ban Xia Decoction to Drain the Heart) is indicated.Gui ZhiTaste and properties: Pungent, sweet, warm.Effects: Releases the exterior, expels pathogens, harmonizes Ying and Wei, warms the middle, descends counterflow.(Induces sweating—pungent and sweet assists yang.)According to the Shen Nong Ben Cao Jing: “Cinnamon twig, taste pungent, warm, non-toxic. It is indicated for counterflow qi, cough, phlegm obstruction, vomiting, benefits joints, tonifies the middle and benefits qi. Long-term use opens the spirit, lightens the body, and prevents aging.In various diseases—Gui Zhi occupies a large part of classical formulas and is indispensable.Three views of classical formulas: exterior-interior view, righteous-evil view, fluid view (effectiveness does not necessarily mean correctness).Taiyin wind—pulse yang is weak, yin is rough and long.It is very important for interior evil to exit, utilizing exterior symptoms to expel wind and cold from the five zang organs, allowing the true essence of the five zang organs to flow smoothly, preventing evil from being trapped.Shaoyin disease is an exterior deficiency cold syndrome, Gui Zhi disperses the exterior and sweetly warms to dispel cold. In Shaoyin disease, throat pain, Ban Xia San (Ban Xia Powder) and decoction are indicated.Ban Xia San formula:Ban Xia (washed), Gui Zhi (peeled), Gan Cao (roasted).The three ingredients, equal parts, each pounded and sifted, combined, mixed with white drink, take a thumb-sized dose three times a day. If unable to take the powder, use one liter of water, decoct seven times, add two thumb-sized doses of the powder, further boil three times, let cool slightly, and swallow little by little.Gui Zhi releases the exterior and expels pathogens, often paired with Ma Huang (Ma Huang Tang, Ge Gen Tang).Harmonizes Ying and Wei (harmonizing Ying and Wei means harmonizing qi, blood, yin, yang, and fluids).Exterior yin syndrome paired with Gan Cao (Gui Zhi Gan Cao Tang, Ban Xia San).Exterior yang syndrome paired with Ma Huang or Ge Gen (Ma Huang Tang, Ge Gen Tang).When Wei is strong and Ying is weak or both are weak, paired with Shao Yao (Gui Zhi Tang, Gui Zhi Jia Shao Yao Tang, Gui Zhi Jia Da Huang Tang, Gui Zhi Jia Hou Po Xing Zi Tang, Dang Gui Si Ni Tang, Huang Qi Gui Zhi Wu Wu Tang, Xiao Jian Zhong Tang, Gui Zhi Fu Ling Wan, Wen Jing Tang).Gui Zhi descends counterflow (upper counterflow—Wu Ling San, fire counterflow—Gui Zhi Long Gu Mu Li, blood counterflow—Wen Jing Tang).Descending qi counterflow, often paired with Zhi Shi (Gui Zhi Sheng Jiang Zhi Shi Tang, Zhi Shi Xie Bai Gui Zhi Tang, Hou Po Qi Wu Tang).Descending water counterflow often paired with Fu Ling (Wu Ling San, Ling Gui Zhu Gan Tang, Ling Gui Jiao Gan Tang, Fu Ling Ze Xie Tang, Gui Zhi Fu Ling Wan, Shen Qi Wan).Descending fire counterflow often paired with Shao Yao, Long Gu, Mu Li. If fire counterflow and fluids are insufficient, often paired with Shao Yao (Xiao Jian Zhong Tang, Zhi Gan Cao Tang, Gua Lou Gui Zhi Tang, Qi Shao Gui Jiu Tang, Gui Zhi Jia Da Huang Tang, Wen Jing Tang); if fire counterflow and fluids are not solid, often paired with Long Gu, Mu Li (Gui Gan Long Mu Li Tang, Gui Zhi Jia Long Gu Mu Li Tang, Gui Zhi Qu Shao Yao Jia Long Gu Mu Li to rescue counterflow, Feng Yin Tang, Chai Hu Jia Long Gu Mu Li Tang).Descending blood counterflow paired with Da Huang (Tao He Cheng Qi Tang, Gui Zhi Jia Da Huang Tang, Bie Jia Jian Wan).To stop body pain, often paired with Fu Zi, Wu Tou, as seen in Gui Zhi Fu Zi Tang, Gan Cao Fu Zi Tang, Gui Zhi Shao Yao Zhi Mu Tang, Gui Zhi Jia Fu Zi Tang, Gui Zhi Qu Shao Yao Jia Fu Zi Tang, Gui Zhi Qu Shao Yao Jia Ma Huang Fu Zi Xi Xin Tang; paired with Wu Tou seen in Wu Tou Gui Zhi Tang.To stop abdominal pain, often paired with Shao Yao, Yi Tang.
