甘咸平。辟邪魔。（鬼最畏唾。东阳方云∶凡人魇死、不得叫呼、但痛咬脚跟及拇指甲
际
、多唾其面、徐徐唤之、自醒也。）消肿毒。明眼目。（时珍曰∶津乃精气所化、人能每旦漱
口擦齿、以津洗目、及常时以舌舐拇指甲、揩目、久久令人光明不昏、又能退翳、凡人有云
翳、但每日令人以舌舐数次、久则真气熏及、自然毒散而翳退矣。）悦肌肤。（五更未语之唾
、涂肿辄消、拭目去障、咽入丹田、则固精而制火、修养家咽津、谓之清水灌灵根、人能终
日不唾、收视返听、则精气常凝、容颜不槁、若久唾则损精神、成肺病、皮肤枯涸、故曰远
唾不如近唾、近唾不如无唾也。咽津不得法、最易成痰、亦宜知也。）
主治下元虚冷。日令童男女以时隔衣进气脐中。甚良。凡人身体、骨节痹痛。令人更互
呵熨
。久久经络通透。又鼻衄金疮。嘘之能令血断。（时珍曰∶医家所谓元气相火、仙家所谓元
阳真火、一也、天非此火不能生物、人非此火不能有生、故老人虚人、与二七以前少阴同寝
、借其熏蒸、最为有益、杜甫诗云∶暖老须燕玉、正此意也、但不可行淫、以丧宝促生尔、
近时术家、令童女以气进入鼻窍脐中精门、以通三田、谓之接补、此亦小法、不得其道者反
以致疾、按续汉书云∶太医史循、宿禁中、寒疝病发、求火不得、众人以口、更嘘其背、至
旦遂愈、异苑云∶孙家奚奴、治虎伤蛇噬垂死者、以气禁之、皆安。）
味甘、咸，性平。能驱除邪祟。（鬼怪最畏惧唾液。东阳地方传说：凡人遭遇魇魅致死，无法呼叫，只需用力咬其脚跟及大脚趾甲边缘，并向其面部多吐唾液，慢慢呼唤其名，患者自然苏醒。）能消除肿毒。能明目。（李时珍说：津液是由精气化生而来，人若能每天早晨漱口擦牙，用唾液清洗眼睛，以及平时常用舌头舔舐大脚趾甲来擦拭眼睛，久而久之能使目光明亮不昏花，还能去除眼翳。凡是有人患有云翳，只需每日让人用舌头舔拭数次，时间久了真气熏蒸，自然毒素消散而眼翳退去。）能润泽肌肤。（五更天未说话前的唾液，涂抹在肿胀处随即消退；用来擦拭眼睛可去除障蔽；咽入丹田，则能固摄精关并制约虚火。修道之人吞咽津液，称为“清水灌灵根”。人若能整天不吐唾沫，收视返听（集中精神内守），则精气常凝聚，容颜不枯槁。如果长久地吐唾沫则会损伤精神，导致肺病，皮肤干枯。所以说，远吐不如近吐，近吐不如不吐。吞咽津液若不得法，最容易生成痰湿，这也应当知晓。）
主治下元虚冷。每天让儿童或男女隔着衣服向肚脐中吹气，效果很好。凡人的身体出现骨节痹痛，让人互相呵气熨烫。久而久之经络就会通透。又有鼻出血和金创（金属利器造成的伤口），吹气能使血液止住。（李时珍说：医家所说的元气相火，与仙家所说的元阳真火，是同一回事。天没有此火不能化生万物，人没有此火不能维持生命。所以老人和体虚之人，与十七岁以前的少阴之气旺盛者同寝，借其气息熏蒸，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，以免丧失宝气缩短寿命。近来一些方术之士，让童女将气导入鼻孔、脐中和精门，以通三田，称为“接补”，这也是小法术，不得其道的人反而会导致疾病。据《续汉书》记载：太医史循，住宿在宫中，寒疝病发作，找不到火源，众人用口对着他的背部反复吹气，直到天亮便痊愈了。《异苑》记载：孙家的奴仆，治疗被虎伤或被蛇咬即将死亡的人，用气禁咒之法，都安然无恙。）
Sweet and salty, neutral in nature. Expels evil spirits. (Ghosts most fear saliva. The folklore from Dongyang states: If a person suffers from nightmare death and cannot cry out, one should bite firmly at the heel and the edge of the big toenail, spit frequently onto their face, and slowly call their name; they will naturally awaken.) Reduces swelling and toxicity. Brightens the eyes. (Li Shizhen said: Saliva is transformed from essence and qi. If a person rinses their mouth and brushes their teeth every morning, washes their eyes with saliva, and often licks their big toenail with their tongue to wipe their eyes, over time it makes the vision bright and clear, removes nebulae (corneal opacity), and treats any clouding of vision by having someone lick the affected area several times daily; eventually, true qi permeates, toxins disperse, and nebulae recede.) Nourishes the skin. (Saliva produced before dawn without speaking reduces swelling when applied; wiping the eyes removes obstructions; swallowing it into the Dantian consolidates essence and controls fire. Cultivators swallow saliva, calling it "clear water irrigating the spiritual root." If a person refrains from spitting all day, focuses inward (shishi fanting), essence and qi remain condensed, and the complexion does not wither. However, excessive spitting damages spirit and causes lung disease, leading to dry skin. Thus, it is said that distant spitting is inferior to near spitting, and near spitting is inferior to no spitting. Improper swallowing of saliva easily generates phlegm, which should be known.)
Indicated for deficiency-cold of the lower yuan. Daily, have children or young men/women blow air through clothing into the umbilicus. Very effective. For body joint bi-pain, have people take turns blowing warm air and applying heat. Over time, meridians and collaterals become unobstructed. Also, for epistaxis and metallic wounds, blowing can stop bleeding. (Li Shizhen said: What physicians call Yuan Qi and Xiang Huo, and what immortals call Yuan Yang and Zhen Huo, are the same. Heaven cannot generate life without this fire; humans cannot sustain life without it. Therefore, for the elderly and the deficient, co-sleeping with youths under seventeen years old (whose Shaoyin qi is vigorous) to borrow their warming vapor is most beneficial. Du Fu's poem says, "To warm the old, one needs Yan Yu," which refers to this meaning. However, sexual intercourse must be avoided to prevent loss of vital essence and shortened lifespan. Recently, some practitioners allow virgin girls to direct breath into the nostrils, umbilicus, and Jingmen to open the Three Fields, called "Jie Bu" (connecting and supplementing). This is a minor technique; those who do not follow the correct method may instead cause illness. According to the *Book of Later Han*, Taiyi Shi Xun stayed in the palace; when his cold hernia attacked and he could not find fire, everyone blew on his back repeatedly until dawn, and he recovered. *Yi Yuan* records that a servant of the Sun family treated victims of tiger bites or snakebites who were near death by using breath prohibition techniques, resulting in safety.)
