人气主要治疗下元（肾与命门）虚寒。每日让童男童女隔着衣服向肚脐中吹气，效果很好。凡是人体骨骼关节痹痛，让人互相呵气并熨烫，久而久之经络就会通畅。又有鼻出血或金属创伤，用气嘘吹能使血液停止。（出自《本草纲目》）
【名称】（李时珍说）医家所说的元气、相火，仙家所说的元阳、真火，其实是一回事。天没有这把火就不能化生万物，人没有这把火就不能维持生命。
【时节】（采集方法）春天食用东方的青气，夏天食用南方的赤气，秋天食用西方的白气，冬天食用北方的黑气，四季中央食用黄气，也大有功效。
【用法】凡是老人、体虚之人以及未满十四岁的少阴之气旺盛者同寝，借助其熏蒸最为有益。（杜甫诗云：“暖老须燕玉”，正是这个意思。）但不可行房事而丧失精气、缩短寿命。近来一些方术之士让童女将气送入鼻孔、肚脐和精窍，以打通上、中、下三田，称为“接补”，这也是小法术，不得其道反而会导致疾病，应当谨慎。
【治疗】（谢承《续汉书》记载）太医史循在宫中值宿时患寒疝病发作，求火不得，众人轮流向他背部呵气，直到天亮便痊愈了。（刘敬叔《异苑》记载）孙家的奴仆治疗被虎咬、蛇咬濒临死亡的人，用气禁咒之法，人都安然无恙。
【解析】（葛洪《抱朴子》记载）人在气之中，气在人之中，天地万物无不依靠气来生存。善于行气的人，对内可以养生，对外可以驱除邪恶。然而行气有法则：从子时到巳时是生气之时，从午时到亥时是死气之时。常在生气之时，用鼻子吸气入内，呼出少而吸入多，闭气并默数数字，从九九、八八、七七、六六、五五递减至止，然后微微吐气，不要发出声音。练习熟练后增加到千次，这叫做胎息。所以善于行气的人可以避免饥渴，可以延年益寿，可以在水上行走，可以居住在水中，可以治愈百病，可以躲避瘟疫。用气嘘水，水会逆流；嘘火，火会远离熄灭；嘘沸汤，手可以探入；嘘金疮，血自然停止；嘘兵刃，刺不能进入；嘘箭矢，箭矢自行射回；嘘狗，狗不吠叫；嘘老虎野狼，它们伏退；嘘蛇蜂，它们不动。吴越地区有禁咒行气的方法，遇到大瘟疫，可以与病人同床而不被传染；遇到精怪魅影，或闻声或现形，掷石放火，用气禁之，都会自行断绝。或被毒蛇咬伤，嘘之即愈。如果在百里之外，遥用手对着男左女右的方向嘘咒，也可以平安。气出于无形，使用它的功效达到这种程度，何况是断谷延年呢？（李时珍按语：这就是我们所说的涵养浩然之气。符篆家取用的祖气就是此法，但那些道士往往气馁，庸人依样画葫芦，怎么能有效呢？）
Ren Qi (Vital Energy) primarily treats deficiency-cold of the Lower Yuan (Kidney and Mingmen). It is beneficial to have young boys and girls blow air into the navel through clothing daily. For bi- pain in bones and joints, mutual blowing and moxibustion/warming can eventually unblock the meridians. Blowing with breath can also stop bleeding from epistaxis or metallic wounds. (From *Bencao Gangmu*)
[Name] (Li Shizhen states): What physicians call Yuan Qi (Primal Qi) and Xiang Huo (Ministerial Fire), and what Daoists call Yuan Yang (Primal Yang) and Zhen Huo (True Fire), are essentially the same. Heaven cannot generate living things without this fire; humans cannot sustain life without it.
[Seasons/Methods] (Collection methods): In spring, consume the Green Qi of the East; in summer, the Red Qi of the South; in autumn, the White Qi of the West; in winter, the Black Qi of the North; and during the transitional periods of the four seasons, consume the Yellow Qi of the Center. These methods are also highly effective.
[Usage] For the elderly, those with deficiency, and youths before the age of fourteen (when Shaoyin energy is robust), sharing a bed and benefiting from their vaporization/moxibustion-like warmth is most advantageous. (As Du Fu wrote: "To warm the old, one needs Yan Yu," referring to this intent.) However, one must not engage in sexual intercourse to avoid losing essence and shortening life. Recently, some practitioners have young girls blow air into the nostrils, navel, and genital openings to open the Upper, Middle, and Lower Sanjiao (Triple Burner), called "Jie Bu" (Connecting and Supplementing). This is a minor technique; if done improperly, it may cause illness, so caution is required.
[Treatment] (Xie Cheng's *Continued Book of Han* records): Taiyi Shi Xun suffered an attack of Han Shan (Cold Hernia) while on duty in the palace. Unable to find fire, people took turns blowing air on his back until dawn, after which he recovered. (Liu Jingshu's *Yi Yuan* records): A servant of the Sun family treated victims bitten by tigers or snakes who were near death using Qi Jin (Qi prohibition/incantation), resulting in their safety.
[Explanation] (Ge Hong's *Baopuzi* records): Humans exist within Qi, and Qi exists within humans. All things in heaven and earth rely on Qi for life. Those skilled in practicing Qi can nurture life internally and repel evil externally. However, there are rules: From Zi hour to Si hour is the time of generating Qi; from Wu hour to Hai hour is the time of dead Qi. One should usually inhale deeply through the nose during the generating Qi time, retaining more than exhaling, holding the breath while counting down from 99, 88, 77, 66, 55, etc., then gently exhale without making sound. Once proficient, increase to a thousand repetitions, known as Taixi (Fetal Breathing). Thus, those skilled in Qi practice can avoid hunger and thirst, prolong life, walk on water, dwell in water, cure hundred diseases, and escape plagues. Blowing Qi at water makes it flow backward; at fire, it extinguishes at a distance; at boiling soup, hands can probe in; at metallic wounds, bleeding stops; at weapons, stabs cannot penetrate; at arrows, they shoot back; at dogs, they do not bark; at tigers and wild wolves, they cower and retreat; at snakes and bees, they remain still. In the Wu and Yue regions, there are incantations for Qi practice. During major epidemics, one can share a bed with patients without infection. When encountering spirits or demons that make sounds or appear, throwing stones or setting fires, Qi prohibition will make them cease. If bitten by a venomous snake, blowing Qi heals immediately. Even from a hundred li away, pointing the hand towards men (left side) or women (right side) and reciting incantations brings peace. Qi emerges from formlessness, yet its efficacy reaches such heights, let alone fasting and longevity. (Li Shizhen notes: This is precisely our cultivation of Haoran Zhi Qi (Noble Spirit). The Talismanic sect uses Zu Qi (Ancestral Qi), which is this method, but those monks often lack Qi, and ordinary people imitating it vainly achieve no results.)
