（《千金》）
治热伤元气，气短倦怠，口渴多汗，肺虚而咳（肺主气，火热伤肺，故气短；金为火制，
不能生水，故口渴；气少，故倦怠；肺主皮毛，虚故汗出；虚火乘肺，故咳。李东垣曰∶津
者，
无制
人参 麦冬（五分） 五味子（七粒）
此手太阴、少阴药也。肺主气，肺气旺则四脏之气皆旺，虚故脉绝短气也。人参甘温，
大补肺气，为君；麦冬甘寒，润肺滋水，清心泻热，为臣；五味酸温，敛肺生津，收耗散之
气，为佐。盖心主脉，肺朝百脉（百脉皆朝于肺，补肺清心），则气充而脉复，故曰生脉也
（人有将死脉绝者，服此能复生之，其功甚大）。夏月炎暑，火旺克金，当以保肺为主，清
晨服此，能益气而祛暑也（李东垣曰∶手阳明大肠，手太阳小肠，皆属足阳明胃。大肠主津，
小肠主液，大肠小肠受胃之阳气，乃能行津液于上焦，溉灌皮毛，充实腠理；若饮食不节，
胃气不充，大肠小肠无所禀气，故津液涸竭焉。又曰∶脉者，元气也。人参之甘，补元气，
泻火热；麦冬之苦寒，补水源而清燥金；五味之酸以泻火，补庚大肠与肺金。又曰∶夏月加

Treats heat damaging the primordial qi, manifesting as shortness of breath, fatigue and listlessness, thirst, and profuse sweating, as well as cough due to Lung deficiency. (Explanation: The Lung governs Qi; fire-heat injuring the Lung causes shortness of breath; Metal is controlled by Fire, failing to generate Water, causing thirst; lack of Qi leads to fatigue; the Lung governs the skin and hair, so deficiency causes sweating; deficient fire harassing the Lung causes cough. Li Dongyuan stated: Jin Ye [Body Fluids], if uncontrolled...)
Renshen (Ginseng Radix), Maidong (Ophiopogonis Radix) (5 fen), Wuweizi (Schisandrae Fructus) (7 grains).
This formula acts on the Hand-Taiyin Lung Meridian and the Hand-Shaoyin Heart Meridian. The Lung governs Qi; when Lung Qi is vigorous, the Qi of the other four Zang organs is also vigorous. Deficiency leads to faint pulse and shortness of breath. Renshen is sweet and warm, greatly tonifying Lung Qi, serving as the Sovereign drug; Maidong is sweet and cold, moistening the Lung, nourishing Water, clearing the Heart, and draining heat, serving as the Minister drug; Wuweizi is sour and warm, astringing the Lung, generating fluids, and consolidating dissipating Qi, serving as the Assistant drug. Since the Heart governs the vessels and the Lung receives all vessels (all vessels converge at the Lung; tonifying the Lung and clearing the Heart), Qi becomes sufficient and the pulse recovers, hence it is called "Sheng Mai" [Generating Pulse] (When a person is near death with an absent pulse, taking this can restore life, its efficacy is great). In summer, when heat is prevalent and Fire controls Metal, protection of the Lung should be the priority. Taking this in the morning can tonify Qi and dispel summer-heat. (Li Dongyuan stated: The Hand-Yangming Large Intestine Meridian and the Hand-Taiyang Small Intestine Meridian both belong to the Foot-Yangming Stomach Meridian. The Large Intestine governs Jin Ye [thin body fluids], and the Small Intestine governs Ye [thick body fluids]. The Large and Small Intestines receive the Yang Qi of the Stomach to transport Jin Ye to the Upper Jiao, irrigating the skin and hair and filling the Cou Li [interstices]; if dietary habits are irregular and Stomach Qi is insufficient, the Large and Small Intestines have no Qi to receive, leading to the exhaustion of Jin Ye. He also stated: Mai [Pulse/Vessels] is Yuan Qi [Primordial Qi]. The sweetness of Renshen tonifies Yuan Qi and drains fire-heat; the bitter-cold nature of Maidong nourishes the source of Water and clears dry Metal; the sourness of Wuweizi drains fire and tonifies Geng Metal [Large Intestine] and Lung Metal. He also stated: In summer, add Huang Qin [Scutellariae Radix] and Gan Cao [Licorice Root] to take.)
Adding Chenpi (Citri Reticulatae Pericarpium) and Zhi Gancao (Prepared Licorice Root) to this formula creates Wuweizi Tang (Schisandra Decoction); forming pills with steamed wheat cake creates Buqi Wan (Qi-Tonifying Pill): treating Lung deficiency with scanty Qi, cough, and spontaneous sweating. Adding Fushen (Poria with Hostwood) to this formula...
