戴元礼认为喘症有多种类型：有痰喘，有人气喘，有胃气虚喘，有火炎上喘。
所谓痰喘，凡是喘息必然伴有痰鸣声；
所谓气喘，表现为呼吸急促但没有痰声；
所谓胃气虚喘，表现为耸肩抬颈喘息不止；
所谓火炎上喘，表现为喘息时轻时重，进食后减轻，吃完后反而加重。
大抵是因为胃中有实火，膈上有稠痰，食物咽下坠入，带动稠痰下行，喘息随即停止；稍过片刻，食物入胃助长火势，痰再次升腾至上，喘息反而大作。不可将其当作胃虚来治疗而使用燥热药物，否则如同以火救火。
小儿患喘病，若脉象滑利且手足温暖者，预后良好（生）；若脉象涩滞且手足寒冷者，预后不良（死）。
一、因感冒风寒导致鼻塞、声音沉重、咳嗽且喘息急迫者，适宜使用三拗汤、华盖散或小青龙汤。
二、痰喘，咽喉中有半有声的痰鸣者，适宜使用千缗汤、半夏汤或抑痰汤。
三、气喘，因肺气不清，呼吸急促且伴有声响者，适宜使用苏子降气汤。
四、胃气虚喘，适宜使用人参保肺汤。
五、火炎上致喘者，适宜使用泻白散。
六、老人素有痰喘旧疾，遇寒暖变化则发作，连绵不断者，适宜使用苏沉九实饮或杏苏散。

Dai Yuanli posited that asthma (Chuan Zheng) manifests in various forms: there is Phlegm Asthma, Qi Asthma, Stomach Qi Deficiency Asthma, and Flaming Fire Ascending Asthma.
Phlegm Asthma is characterized by wheezing accompanied by the sound of phlegm;
Qi Asthma presents with rapid breathing but without phlegm sounds;
Stomach Qi Deficiency Asthma involves heaving shoulders and pulling the neck in continuous panting;
Flaming Fire Ascending Asthma features intermittent severity, where symptoms alleviate after eating but worsen shortly thereafter.
Generally, this occurs because there is Excess Fire in the stomach and thick phlegm above the diaphragm. When food is swallowed and descends, it drags the thick phlegm down, causing the asthma to cease temporarily. However, once the food enters the stomach and fuels the fire, the phlegm rises again, causing the asthma to flare up severely. It must not be treated as Stomach Deficiency using drying and hot herbs, for this would be akin to adding fire to fire.
For children suffering from asthma, if the pulse is slippery and the hands and feet are warm, the prognosis is good (survival); if the pulse is choppy and the hands and feet are cold, the prognosis is poor (death).
1. For cases caused by contracting Wind-Cold, resulting in nasal congestion, heavy voice, cough, and urgent asthma, San'ao Tang (Three Unrestrained Decoction), Huagai San (Canopy Powder), or Xiao Qinglong Tang (Minor Blue Dragon Decoction) are appropriate.
2. For Phlegm Asthma with phlegm sounds in the throat, Qianmin Tang (Thousand Strings Decoction), Banxia Tang (Pinellia Decoction), or Yi Tan Tang (Suppress Phlegm Decoction) are appropriate.
3. For Qi Asthma due to unclear Lung Qi, presenting with rapid breathing and audible sounds, Suzi Jiangqi Tang (Perilla Seed Descending Qi Decoction) is appropriate.
4. For Stomach Qi Deficiency Asthma, Renshen Baofei Tang (Ginseng Protecting Lung Decoction) is appropriate.
5. For asthma caused by Flaming Fire Ascending, Xiebai San (Drain White Powder) is appropriate.
6. For elderly patients with chronic Phlegm Asthma that recurs upon changes in cold and warmth, continuing endlessly, Suchen Jiushi Yin (Perilla and Atractylodes Nine Solidity Drink) or Xingsu San (Apricot Kernel and Perilla Powder) are appropriate.
7. For individuals with robust constitution exhibiting Phlegm Asthma with Heat, Qishen Dingchuan Tang (Seven Spirits Calming Asthma Decoction) is appropriate.
