    Prescriptions for Relieving Exterior Syndromes

    Those that are mainly composed of diaphoretics and can induce diaphoresis, expel pathogenic factors from muscles and skin, promote eruptions, and be used to treat exterior syndromes, fall into this category.
     
    Since exterior syndromes cover two types, namely wind-cold type and wind-heat type, prescriptions for relieving exterior syndromes are divided into prescriptions for relieving exterior syndrome with pungent-warm drugs and those for relieving exterior syndrome with pungent-cool drugs accordingly.
     
    The former mainly comprises drugs with pungent flavor and warm property for relieving exterior syndrome. It is capable of expelling wind and cold and applicable to exterior syndrome due to wind-cold, while the latter, pungent and cool drugs for relieving exterior syndrome, capable of dispelling wind and removing heat and applicable to exterior syndrome caused by wind-heat.
     
    Prescriptions for relieving exterior syndrome cannot be decocted long in order to prevent the drug property from dissipating and influencing the curative effect. Besides the patient should take the decoction warm and pay attention to keeping warm by himself afterwards to ensure mild perspiration over the body. In doing so, the pathogenic factors will be expelled from the exterior.
     
    Prescriptions Pungent in Flavor and Warm in Property for Relieving Exterior Syndromes
                         Mahuang Tang
                     (Ephedra Decoction)
    Source: Shanghan Lun (Treatise on Exogenous Febrile Diseases).
    Ingredients :
    No. 1 Mahuang (Herba Ephedrae) 9 g
    No. 2 Guizhi (Ramulus Cinnamomi) 6 g
    No. 3 Xingren (Semen Armeniaccaz Amarum) 6 g;
    No. 4 Zhigancao (Rad/x Gl~cyrrhizae Praeparatae) 3 g.
     
    Administration: Decoct the above drugs in water for oral use.
     
    Actions: Inducing perspiration to relieve exterior pathogenic factors, dispersing the lung to relieve asthma.
     
    Clinical Application: This recipe is for exterior-excess syndrome due to exogenous wind-cold, marked by aversion to cold, fever, headache, general aching, dyspnea without perspiration, thin and whitish tongue fur, and superficial and tense pulse. It is applicable to common co1d, flu, acute bronchitis, bronchial asthma and other diseases which chiefly manifest aversion to cold without perspiration, cough and dyspnea. If complicated with pathogenic dampness marked by arthralgia, heaviness of the body, add Baizhu (RiLizoma Atractylodis Macrocephalae) to eliminate dampness, thus making a new one entitled Mahuang Jiazhu Tang. In case of mild aversion to cold but chiefly asthma, subtract Guizhi (Ramulus Cinnamoni) to make a recipe entitled San'an Tang specially for dispersing the lung to relieve asthma. In case of serious aversion to cold without perspiration and general aching body accompanied by dysphoria due to interior heat, double the dosage of Mahuang (Herba Ephedrae) to enhance the petency of inducing perspiration for eliminating the pathogenic factors and add Shigao (Gypsum Fibrosum ) to clear away the interior heat, called Da Qinglong Tang.
     
    Eluvidation : The syndrome is due to attack of windcold on the exterior, obstruction of defensive qi, stagnation of interstitial space, and failure of pulmonary qi to disperse. It should be treated by inducing perspiration to expel pathogenic factors from the exterior and dispersing the lung to relieve asthma. In this recipe, ingredient No.1 acts as the monarch drug. It is capable of inducing sweating to dispel exogenous pathogenic factors and dispersing the lung to relieve asthma. Ingredient No. 2, as the minister drug, is capable of dispersing pathogenic cold by warming the meridians. Ingredient No. 3 capable of relieving stagnant lung-qi and No. 1 serve as adjuvant drug to enhance the effect of relieving cough and asthma. The last ingredient serves as the guiding drug, capable of mediating drug properties and invigorating qi and enriching midenergizer so as to prevent ingredients No. 1 and No. 2 from inducing excessive sweating to impair the vital-qi
     
    Cautions: The recipe is contraindicated for the exterior syndrome due to wind-cold with sweating because it is drastic in inducing sweating. So patients with general debility, blood deficiency and serious interior heat should use it with great caution.
