哮證

哮證發作時呼吸氣促，伴有痰鳴聲響，即西醫的哮喘。

在中醫角度，哮喘有虛有實，但多為本虛夾實，即患者本身體質偏弱，當中可因反覆外感或咳嗽遷延不癒引致肺虛，平素過食生冷寒食，或嗜吃甘肥食物而致脾虛，或久病體弱而成腎虛，諸虛均令身體水液代謝受影響，當水液不能如常排走，則可留於體內而成痰飲；此痰飲就成為哮喘的病根，即之前提及的本虛夾實當中的實邪。每當遇氣候轉變、反覆外感或飲食不當等因素，隱伏的痰飲則會被引動於體內，阻塞氣道，令本應下降之肺氣上逆，引致呼吸不暢、痰鳴如吼，甚則氣息喘促而引發哮喘。

中醫治哮喘主要分為發作期及緩解期。發作期以袪邪平喘為主，一方面把引發哮喘之痰飲袪除，另一方面使肺氣回復正常而不上逆作喘，以減輕患者痛苦；而緩解期的治療則以扶正為本，讓患者本虛之身體日漸強壯，免再生痰飲，並助以袪痰，讓舊有伏痰得去清除，從而達到治本之目的。

Asthma is the onset of shortness of breath, accompanied by the sound of phlegm. In TCM perspective, asthma can broadly be divided into 2 types of syndromes: Deficiency or Excess, or may be a combination of both. Patients with weak body constitution frequently suffered from flu, cold or coughing, can cause lung deficiency. Intake of cold drinks or food, or too much fat will weaken the spleen. Chronic disease will hurt the kidneys. The deficiency of lung, spleen and kidney systems will affect metabolism of liquid in the body, and phlegm will occur as a result. Climatic change, catching a cold or eating inappropriately may trigger asthma, causing breathlessness and wheezing. During exacerbation period, Chinese medicine is used to clear the phlegm and pacify the Chi of the lung. In remission phase, prescription will target the fundamental cause of the illness. Treatment will aim at strengthening the weak body constitution so as to cure the root cause of asthma and phlegm.
