《诸病源候论》说：短气，是指普通人没有寒热症状，但呼吸短促、气息不足以维持正常呼吸，这是体质实盛的表现。实证则气机旺盛，气机旺盛则导致气逆而运行不通。
《僧深方》治疗短气几乎断绝、气息不足以维持、心中烦乱扰动的竹根汤方：
竹根（一斤） 麦门冬（一升） 甘草（二两） 大枣（十枚） 粳米（一升） 小麦（一升）。以上六味药，用水一斗，先煮麦米至熟后捞出，再加入其他药物，煎煮取汁二升七合，每次服用八合，每日三次。如果患者无法饮水，可用棉絮蘸药汁滴入口中。
《医门方》治疗胸中痞闷堵塞、短气，或者腹部拘急疼痛的方剂：
茯苓（四两） 甘草（二两） 半夏（三两） 生姜（三两） 杏仁（一百颗）。
用水七升，煎煮取汁二升半，滤去药渣，分三次温服。两次服药间隔时间约为步行八九里路的时间，待气机通畅则病愈。如果气机仍不能下行，可加大黄、槟榔。
《千金方》治疗短气且不能说话的方剂：
栀子（十四枚） 豆豉（七合）。

又说：冷气导致的短气方：花椒五两，用绢袋装好，浸入酒一升中，浸泡二十一天，随意服用。
《诸病源候论》说：少气，这是由于脏腑之气不足所致。肺主司气并主管呼吸，脏腑之气不足，则呼吸微弱而表现为少气。

The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: Shortness of breath refers to a condition in ordinary people who have no chills or fever, yet experience shortness of breath with insufficient respiration. This indicates a constitution of excess. Excess conditions involve vigorous Qi; when Qi is vigorous, it may become rebellious and obstructed.
The *Seng Shen Fang* (Prescriptions by Monk Shen) treats severe shortness of breath approaching cessation, insufficient respiration, and restlessness with the Bamboo Root Decoction (Zhugen Tang):
Bamboo Root (1 jin), Ophiopogon Tuber (Ophiopogonis Radix, 1 sheng), Licorice Root (Gancao, 2 liang), Jujube (Dazao, 10 pieces), Coix Seed (Jingmi, 1 sheng), Wheat (Xiaomai, 1 sheng). These six ingredients are boiled in 1 dou of water. First, boil the wheat and coix seed until cooked, then remove them. Add the remaining herbs and boil to obtain 2.7 sheng of decoction. Take 0.8 sheng per dose, three times daily. If the patient cannot drink, dip cotton wool in the decoction and drip it into the mouth.
The *Yimen Fang* (Medical Gate Prescriptions) treats chest oppression and blockage, shortness of breath, or abdominal urgency and pain:
Poria (Fuling, 4 liang), Licorice Root (Gancao, 2 liang), Pinellia Tuber (Banxia, 3 liang), Fresh Ginger (Shengjiang, 3 liang), Apricot Seed (Xingren, 100 pieces).
Boil in 7 sheng of water to obtain 2.5 sheng of decoction. Strain the dregs and divide into three warm doses. The interval between doses should be approximately the time it takes to walk for eight or nine li. When Qi flows freely, the disease will improve. If Qi does not descend, add Rhubarb (Dahuang) and Areca Seed (Binglang).
The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) treats shortness of breath accompanied by inability to speak:
Gardenia Fruit (Zhizi, 14 pieces), Prepared Soybean Seed (Chidou, 0.7 sheng).
Boil the prepared soybeans in 2 sheng of water to obtain 1.5 sheng. Remove the beans, add the gardenia fruits, and boil to obtain 0.8 sheng. Take 0.5 sheng per dose.
It also states: For sudden shortness of breath, crush fresh leeks to extract juice and take 1 sheng; recovery is immediate.
For shortness of breath caused by cold Qi: Take 5 liang of Sichuan Pepper (Huajiao), place it in a silk bag, soak it in 1 sheng of wine for 21 days, and consume as desired.
The *Zhubing Yuanhou Lun* states: Deficient Qi (Shaoyi) results from insufficiency of Zang-Fu Qi. The Lung governs Qi and controls respiration. When Zang-Fu Qi is deficient, respiration becomes weak, manifesting as deficient Qi.
The *Guangji Fang* (Guangji Prescriptions) treats inability to eat due to cold Qi in the abdomen and deficient Qi with the Regulating the Middle Pill (Tiaozhong Wan):
Ginseng Root (Renshen, 5 liang), Poria (Fuling, 5 liang), Licorice Root (Gancao, 5 liang), Atractylodes Macrocephala Rhizome (Baizhu, 5 liang), Dried Ginger (Ganjiang, 4 liang).
Pulverize and sieve the herbs, mix with honey to form pills. Take 30 pills (size of sophora seeds) with warm wine on an empty stomach, twice daily and once at night. If beneficial, continue preparation. If alcohol is not consumed, swallow with decocted jujube tea.
The *Qianjin Fang* treats lack of vitality/energy (Faqi):
Goji Leaf (Gouqiye, 2 liang), Fresh Ginger (Shengjiang, 2 liang).
Boil in 3 sheng of water to obtain 1 sheng of decoction. Take all at once.
The *Ge Shi Fang* (Prescriptions by Master Ge) treats sudden lack of vitality, inability to replenish Qi, and breathing with shoulder elevation:
Dried Ginger (Ganjiang, 3 sheng), chopped, soaked in 1 sheng of wine. Take 1 sheng per dose, three times daily.
Another prescription: Measure the distance below the heart using the thumb joint, moxa-ignite three moxa cones (zhuang) at this point for cure.
Another prescription: Ephedra Stem (Mahuang, 3 liang). First, boil in 5 sheng of water for one boiling, skim off the foam, then add Licorice Root (Gancao, 2 liang) and Apricot Seed (Xingren, 60 pieces). Boil to obtain 2.5 sheng of decoction,
