喘症分为虚证和实证。因受风邪诱发而发作的，属于实邪，通过发散邪气即可痊愈。其症状表现为喉咙发出像水鸡一样的叫声，喘息时必须耸起肩膀，胸闷气短仿佛要死掉一样。虽然看起来病势沉重，但实际上病情较轻，这属于外感疾病而非内伤疾患。方剂选用射干止喘汤，服用一剂即可痊愈，不需要再服第二剂。这个方子虽然都是祛邪散风的药物，但含有补益性质的药材以相互制约，使得邪气去除而正气不亏损。如果方中只有补益之味而没有散邪之品，或者只有发散而没有补益，那么即使风邪被去除，喘息也会立刻消除，但日后必定会有再次感受外邪的隐患。不如趁其初起之时，预先做好防范准备。至于虚喘又是怎样的呢？口中微微喘息，不至于耸肩，这实际上是短气的症状，看似喘息实则不是喘息。询问病情，必然有气从肚脐间向上冲逆，便觉得呼吸不安宁。这是肾虚到了极点，元阳仅存一线微弱之气，牵连未绝而即将断绝的状态。治法应当大补肾阴之水并兼补元阳之气，使虚火下潜而元阳得以延续。方剂选用生水归源散。此方神妙至极，这种病非此等方剂不能将将亡的元气挽回，补充濒临枯竭的真水。服用一剂则喘息减轻，两剂则喘息安定，三至四剂则身体安宁。这样才可以安然入睡，且没有气上冲的祸患。如果不使用我的方子，必然导致死亡；即便症状稍减，也能奏效，然而旷日持久只会增加困顿疲惫。与其日后多服药饵，还不如趁其初起之时，立即按照我制定的方剂大量给予患者痛饮，能迅速去除病痛才是痛快之事。

Asthma (Chuan Zheng) is categorized into deficiency and excess patterns. When asthma is triggered by wind pathogen, it belongs to an excess pattern; the disease can be cured by dispersing the pathogen. The symptoms include a rattling sound in the throat resembling that of a water chicken, panting accompanied by shoulder elevation, chest tightness, and a sensation of suffocation as if dying. Although the clinical presentation appears severe, the actual condition is relatively mild, indicating an external contraction disease rather than an internal injury disorder. The prescribed formula is Shegan Zhichuan Tang (Belamcanda Asthma-Relieving Decoction), which cures the patient after one dose without the need for a second dose. This formula consists mainly of herbs that dispel pathogens and scatter wind, but includes tonifying ingredients to moderate their effects, ensuring that while the pathogen is eliminated, the healthy qi remains unharmed. If the formula contained only tonifying herbs without pathogen-dispersing ones, or only dispersing herbs without tonification, although the wind pathogen might be expelled and asthma temporarily relieved, there would inevitably be a predisposition to future re-infection. It is better to take preventive measures at the onset of the disease.
As for deficiency-type asthma, how does it present? The patient breathes slightly rapidly through the mouth without shoulder elevation. This is actually a symptom of shortness of breath (Duan Qi), which resembles asthma but is not true asthma. Upon inquiry, there is invariably a sensation of qi rushing upward from the umbilical region, causing restless breathing. This indicates extreme kidney deficiency, where the original yang (Yuan Yang) is reduced to a faint thread of vitality, barely connected and on the verge of extinction. The treatment method should involve significantly nourishing the water of the Kidney (Kidney Yin) while simultaneously tonifying the original yang qi, thereby subduing deficient fire and sustaining the original yang. The prescribed formula is Shengshui Guiyuan San (Water-Generating Source-Returning Powder). This formula is extraordinarily effective; such critical conditions cannot be rescued from impending death or replenishment of nearly exhausted true yin without this specific prescription. After one dose, asthma alleviates; after two doses, asthma stabilizes; after three to four doses, the body becomes peaceful. Thus, the patient can sleep soundly without the hazard of rebellious qi ascending. If my formula is not used, death is inevitable; even if symptoms slightly decrease with other treatments, it takes a long time and merely increases exhaustion. Rather than taking numerous medications later, it is far superior to administer my prescribed formula generously at the earliest stage to quickly eradicate the disease.
