喜和笑都属于心火。《内经》说：心脏藏神，神气有余就会笑个不停。又说：在五脏中对应心，在五声中对应笑，在五志中对应喜。又说：精气汇聚于心就会喜。又说：火气太过称为赫曦（盛大明亮），赫曦之年，人们容易患笑、狂、妄的病。又说：少阴君火所主之时，会出现喜笑的症状，就是这种情况。
刘河间说：笑，像草木繁茂、清新淑丽、舒展荣耀、彰显外露，这是火的化象，所以喜是心火的情志表现。喜极而笑，就像燃烧太旺而发出笑声的意象一样。所以生病导致笑的，是心火过盛。
有一位妇女患喜笑不止的病，已经半年了，众医都没有办法，求治于戴人（张从正）。戴人说这病容易治。用成块的沧盐二两多，用火烧至通红，放冷后研成细末，用一大碗河水，同煎至煮沸三五次，放温后分三次服用，用钗子探入喉中催吐，吐出热痰五升。接着服用降火药，火邪主治用苦味药，黄连解毒汤就是这类药。没过几天，笑就停止了。《内经》说：神气有余的人，会笑个不停。所谓神，就是心火。火遇到风就会燃烧，所以笑的意象属于火。五行之中只有火与笑相关。曾经治疗一位老年男子笑个不停、口流涎水的病，用黄连解毒汤加半夏、竹叶、竹沥、姜汁，笑就止住了。针刺灸疗喜笑之症，只取心包经这一条经脉。经文说：手厥阴心包经发生病变，会出现面红目黄、喜笑不休等症状，需详细辨别盛、虚、热、寒、陷下等不同情况来选取穴位治疗。
怒在阴阳关系中，是因为阴气闭遏阳气，使阳气不得伸展。经文说：阴气出于阳位则发怒。又说：血气上逆，气机下沉，会导致心烦冤屈、容易发怒。李东垣说：多怒的人，是风热陷入下部所致。怒属于肝胆。经文说：在五脏中对应肝，在五志中对应怒。又说：肝脏藏血，血气有余就会怒。又说：胆也主怒。
朱丹溪治疗怒气的方子，用香附末六两、甘草末一两，混合均匀，用白开水调服五钱。因运气因素导致的怒，都属木气太过。经文说：木气太过称为发生，发生之年，人们容易患怒的病。又说：岁运木气太过，风气流行，严重时容易善怒。又说：岁运土气不及，风气反而大行，民众容易患善怒的病。
怒的禁忌是多生厥逆。经文说：人体的阳气，如果大怒，会导致形体之气隔绝，血液郁积于上部，使人发生薄厥（气血逆乱之厥证）。又说：暴怒伤阳。又说：怒则气机上逆，严重时会导致呕血及完谷不化的泄泻。一般大法是用悲胜怒，或者用药补益肺金以平抑肝木。
Joy and laughter both belong to Heart Fire. The *Classic of Internal Medicine* (*Huangdi Neijing*) states: The Heart houses the Spirit (*Shen*); when the Spirit is in excess, one laughs incessantly. It further states: In the Zang organs, it corresponds to the Heart; in the vocal sounds, it corresponds to laughter; in the emotions, it corresponds to joy. It also states: When Essence and Qi converge in the Heart, there is joy. Furthermore: Excessive Fire is termed "He Xi" (brilliant and expansive). In years of He Xi, diseases such as laughing, mania, and delirium occur. Additionally: When Shaoyin (Ministerial Fire) prevails, symptoms include joy and laughter.
Liu Wansu stated: Laughter, like the luxuriant growth and fresh elegance of vegetation, represents expansion, glory, and manifestation; this is the transformation of Fire. Therefore, joy is the emotion of Heart Fire. Extreme joy leading to laughter is akin to the image of roaring flames burning too intensely. Thus, pathological laughter indicates an excess of Heart Fire.
A woman suffered from incessant laughter for half a year. Physicians were at a loss, so she sought treatment from Dai Ren (Zhang Congzheng). Dai Ren said, "This is easy to treat." He prescribed over two taels of block-shaped Cangyan (Sea Salt), heated it in fire until red-hot, allowed it to cool, and ground it into fine powder. This was decocted with one large bowl of river water until it boiled three to five times. After cooling to a warm temperature, it was taken in three doses. A hairpin was used to stimulate the throat to induce vomiting, expelling five sheng of hot phlegm. Subsequently, a heat-clearing formula was administered. Since Fire is treated with bitter flavors, Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) was used. Within a few days, her laughter ceased. The *Neijing* states: "When the Spirit is in excess, there is incessant laughter." What is referred to as the Spirit is Heart Fire. Fire flares up when encountering wind; thus, the image of laughter belongs to Fire. Among the Five Elements, only Fire is associated with laughter. I once treated an elderly man who laughed incessantly and drooled. Using Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) added with Banxia (Pinellia Rhizome), Zhuye (Bamboo Leaf), Zhuli (Bamboo Sap), and Jiangzhi (Ginger Juice), his laughter stopped. For acupuncture and moxibustion treating joy and laughter, one should exclusively select the Pericardium Meridian of Hand-Jueyin. The classics state: When the Pericardium Meridian of Hand-Jueyin is disturbed, it causes redness of the face, yellowing of the eyes, and incessant laughter. One must carefully distinguish between excess, deficiency, heat, cold, and sinking conditions to select appropriate points.
Anger, in terms of Yin and Yang, arises when Yin obstructs Yang, preventing Yang from extending. The classics state: When Yin emerges into Yang, anger occurs. It also states: When Blood accumulates above and Qi sinks below, it causes mental distress, grievance, and irritability. Li Dongyuan stated: Those prone to anger suffer from Wind-Heat sinking downward. Anger is associated with the Liver and Gallbladder. The classics state: In the Zang organs, it corresponds to the Liver; in the emotions, it corresponds to anger. It also states: The Liver stores Blood; when Blood is in excess, anger occurs. It further states: The Gallbladder is also associated with anger.
Zhu Danxi’s formula for treating anger consists of Xiangfu Powder (Cyperi Rhizoma) six taels and Gancao Powder (Licorice Root) one tael, mixed uniformly and taken with five qian dissolved in white boiling water. Anger caused by climatic factors (Yunqi) all belong to excessive Wood. The classics state: Excessive Wood is called "Fa Sheng" (initiating growth). In years of Fa Sheng, diseases involving anger occur. It also states: In years of excessive Wood, Wind circulates widely, and severe cases result in irritability. Furthermore: In years where Earth is deficient, Wind acts excessively, and the people suffer from irritability.
Anger has contraindications regarding the frequent occurrence of Jue Ni (Reversal Cold/Stroke-like conditions). The classics state: When a person becomes extremely angry, their form and Qi become severed, causing Blood to stagnate in the upper body, leading to Bo Jue (a type of syncope due to blood rushing upward). It also states: Violent anger injures Yang. Furthermore: Anger causes Qi to rebel upward; in severe cases, it leads to hematemesis (vomiting blood) or diarrhea with undigested food. The general therapeutic principle is to overcome anger with sorrow, or to use herbs to tonify Lung Metal to pacify Liver Wood.
