黄帝问：人之所以流口水，是什么气导致的？岐伯回答：饮食进入胃中，如果胃中有热，就会导致寄生虫蠕动；寄生虫蠕动会使胃壁松弛；胃壁松弛则廉泉穴（位于舌下的穴位）开启，所以口水流出。治疗应补益足少阴肾经。
口水是脾所化生的体液。脾虚而胃热，导致津液泛滥，从舌下的廉泉穴流出并溢出口外，这是由于虫动引起的。婴幼儿常出现这种情况。普通人熟睡时也有此病，因为昏睡时脾气弛缓，不能固摄口水。补益足少阴肾经，使廉泉之气下达，口水就能回归于脾。
黄帝问：人之所以打哈欠，是什么气导致的？岐伯回答：胃气不实则各条经脉虚弱，经脉虚弱则筋脉懈怠松弛，筋脉懈怠松弛则在行房用力后，气不能恢复，所以产生打哈欠的现象。根据病变所在部位，补益分肉之间（肌肉间隙）。
“欠”音同“妥”，指身体和头部下垂，无力振作的样子。胃是水谷之海，主要滋润宗筋（全身筋膜），宗筋主束骨而利关节。胃气虚，所以筋脉都虚弱，懈怠无力，呈现出垂头丧气的景象。用药应当助养胃气。用针刺补益分肉之间，是因为脾胃主管肌肉的缘故。
黄帝问：人之所以悲伤哭泣流泪涕，是什么气导致的？岐伯回答：心是五脏六腑的主宰；眼睛是众多经脉汇聚的地方，也是上焦津液通行的通道；口鼻是气体进出的门户。所以悲哀愁忧会导致心动，心动则五脏六腑都摇动，摇动则众脉感应，众脉感应则液道开启，液道开启，所以眼泪和鼻涕流出。津液是用来灌注精髓、濡润空窍的，所以上焦津液通道开启就会流泪，流泪不止则津液枯竭，津液枯竭则精髓得不到灌注，精髓得不到灌注则眼睛看不见东西，所以称之为“夺精”。治疗应补天柱穴（位于颈后发际处的膀胱经穴位）。
眼泪是肝所化生的体液，鼻涕是肺所化生的体液。大凡气血津液，都出于脏腑，而脏腑之气，都随心意驱使，因为心是一身的主宰。所以因情志触动心脏，则脏腑之气摇动，津液随气外泄，就像受惊则出汗，恍惚则出汗，汗是心的体液，其余情况可类推。肝开窍于目，流泪过多导致肝液枯竭，则眼睛看不见东西，所以西河痛子（一种眼疾患者）因此失明。天柱穴是膀胱经穴位，位于项部颈后发际处，说用针刺补益此穴，是因为膀胱为州都之官，津液藏于此，补此穴是为了补救已受损的津液。
The Yellow Emperor asked: What qi causes a person to drool? Qibo answered: Food and drink enter the stomach. If there is heat in the stomach, parasites move; when parasites move, the stomach becomes relaxed; when the stomach is relaxed, the Lianquan acupoint (an acupoint located under the tongue) opens, thus causing saliva to flow out. Treatment should involve tonifying the Foot-Shaoyin Kidney Meridian.
Saliva is the fluid of the Spleen. When the Spleen is deficient and the Stomach has heat, fluids overflow, exiting from the Lianquan acupoint under the tongue and spilling outside the mouth, due to the movement of parasites. This is common in infants. Ordinary people also experience this during deep sleep, because during drowsiness, Spleen Qi relaxes and fails to control saliva. Tonifying the Foot-Shaoyin Kidney Meridian allows the Qi of Lianquan to descend, so that saliva can return to the Spleen.
The Yellow Emperor asked: What qi causes a person to yawn? Qibo answered: When Stomach Qi is not solid, all meridians become deficient. When meridians are deficient, sinews and vessels become lax and slack. When sinews and vessels are lax and slack, after exertion during sexual intercourse, Qi cannot recover, thus causing yawning. Based on the location of the pathology, tonify the space between muscles.
"Yawn" (Qian) refers to the appearance of the body and head drooping, lacking the strength to lift them. The Stomach is the Sea of Water and Grain, primarily moistening the Zongjin (General Sinews). The Zongjin binds the bones and facilitates joint movement. When Stomach Qi is deficient, sinews and vessels become weak, leading to laxity and weakness, presenting an image of dejection. Medication should aid Stomach Qi. Acupuncture tonification of the intermuscular spaces is used because the Spleen and Stomach govern muscles.
The Yellow Emperor asked: What qi causes a person to weep with tears and mucus due to sorrow? Qibo answered: The Heart is the master of the five zang organs and six fu organs. The eyes are where numerous meridians converge and serve as the pathway for upper jiao fluids. The mouth and nose are the portals for Qi. Therefore, sorrow, grief, and worry cause the Heart to move; when the Heart moves, the five zang organs and six fu organs all tremble. Trembling stimulates the numerous meridians; stimulation of the numerous meridians opens the fluid pathways. Once the fluid pathways open, tears and mucus flow out. Fluids are used to nourish essence and moisten orifices. Thus, when the upper fluid pathway opens, one cries. If crying does not stop, fluids are exhausted. When fluids are exhausted, essence is not nourished. When essence is not nourished, the eyes lose vision. Hence, it is called "Loss of Essence." Treatment should involve tonifying the Tianzhu acupoint (an acupoint on the Bladder Meridian located at the back of the neck).
Tears are the fluid of the Liver, and nasal mucus is the fluid of the Lung. Generally, Qi, Blood, and Body Fluids originate from the zang-fu organs, and the Qi of these organs is directed by the Heart, as the Heart is the master of the body. Therefore, emotional disturbance moves the Heart, causing organ Qi to tremble and fluids to leak out with Qi. For example, fright causes sweating, and confusion causes sweating; sweat is the fluid of the Heart. Other cases can be inferred similarly. The Liver opens into the eyes. Excessive tearing depletes Liver fluids, resulting in blindness. Thus, patients of Xihe Tongzi (a type of eye disease) may go blind due to this. Tianzhu is an acupoint on the Bladder Meridian, located at the nape behind the hairline. The reason for using acupuncture to tonify this point is that the Bladder is the Officer of the Capital, storing fluids; tonifying it replenishes the damaged fluids.
