（唇未肿则肺热，燥则唇干，利湿热唇烂，肺热则唇生核，狐惑则唇浓上疮或
则唇下疮，风则唇动 ，虚则唇白无色，寒则唇青或噤。）
舌乃心之苗，心宁则舌安，心扰则舌乱。且肺之络又连舌本，心肺有热，其苗自不能宁，故搐弄不息，
长出不收。脾乃仓廪之官，其华在唇，且胃脉环于唇口，咂唇者、硬肿者，乃是脾火也。若破荷叶浸软贴之，
或辰砂和蜜敷之，倘若唇肉已伤，不治。疹回后倘有此症，重用黄连、石膏、莲心、栀、柏，以清心苗。
盖舌乃心苗，口为脾窍，火降则热自疏矣。
发狂一症，虽不得见，然总因风寒外束，腠理闭密，大肠干燥，身热无汗，毒火郁结而不得发越故也。
初起用麻黄散加大黄，回后用石膏（四两）、知母、黄连（各一钱）等味，治之可愈。
《经》云∶烦躁者，毒瓦斯壅塞并表里不宁也。如抓搔者，疹痒也。不安者，内热也。呻吟者，疼也。
又烦者，气血燥也。《经》云∶内烦外躁，小便不通，小肠热积也。 疹每有此症，或至昼夜不安。
谵语发狂，啼叫多时，治宜发汗兼通大小便，《经》云∶心烦乱用凉膈散，快胸又疏表，透毒凉解清火以
去其根。又云∶肾燥故心躁，火屈于水而出也。《经》云∶肾枯燥急食辛以润之。又肺主烦，肾主燥，有痰，
有火，有毒，有虫，有痒，用黄芩、黄连、麦冬、知母、贝母、连翘、车前、羚羊、犀角、防风、胆
草、干葛、冬花、茯苓、柴胡、山栀、槐花、石膏、栝蒌仁等味，
又加玄参、生甘草、茯苓、山栀解清肺火，宜重或用大黄、六一散之类。
(Lips not swollen indicate Lung Heat; dryness causes lips to be dry; damp-heat leads to lip ulceration; excessive Lung Heat results in nodules on the lips; Huo or disease (a condition characterized by oral and genital ulcers) presents with purulent sores on the upper or lower lips; Wind causes lip tremors; deficiency manifests as pale, colorless lips; Cold causes blueish lips or lockjaw.)
The tongue is the sprout of the Heart. When the Heart is tranquil, the tongue is stable; when the Heart is disturbed, the tongue becomes chaotic. Furthermore, the collaterals of the Lung connect to the root of the tongue. If there is heat in the Heart and Lung, their external manifestation cannot remain tranquil, resulting in continuous twitching and protrusion of the tongue that fails to retract. The Spleen is the official responsible for granaries (digestion), and its luster manifests in the lips. Additionally, the Stomach meridian encircles the lips and mouth. Lip smacking, hardness, and swelling are signs of Spleen Fire. Applying softened broken lotus leaves or a mixture of Cinnabar and honey externally may help; however, if the lip tissue is already damaged, it is incurable. After the rash subsides, if these symptoms persist, heavy doses of Huanglian (Coptidis Rhizoma), Shigao (Gypsum Fibrosum), Lianxin (Nelumbinis Plumula), Zhizi (Gardeniae Fructus), and Huangbai (Phellodendri Cortex) should be used to clear the Heart's sprout. Since the tongue is the sprout of the Heart and the mouth is the orifice of the Spleen, reducing Fire will naturally dissipate Heat.
The syndrome of mania, though not always observed directly, generally arises from external constraint by Wind-Cold, closure of the interstices (Cou Li), dryness of the Large Intestine, fever without sweating, and the郁结 (stagnation) of toxic fire that cannot vent. In the initial stage, Mahuang San (Ephedra Powder) combined with Dahuang (Rhei Radix et Rhizoma) is used. After the rash recedes, treatment with Shigao (Gypsum Fibrosum, 4 liang), Zhimu (Anemarrhenae Rhizoma), and Huanglian (Coptidis Rhizoma, 1 qian each) can lead to recovery.
The Classics state: Irritability and restlessness result from the obstruction of toxic pathogens and disharmony of the interior and exterior. Scratching indicates pruritus associated with the rash. Restlessness indicates internal Heat. Moaning indicates pain. "Fan" (vexation) refers to dryness of Qi and Blood. The Classics state: Internal vexation with external agitation and urinary retention indicate accumulation of Heat in the Small Intestine. This symptom often occurs in measles patients, causing restlessness day and night.
Delirium, mania, and prolonged crying require treatment involving diaphoresis (sweating) and unblocking both the greater and lesser bowels. The Classics state: For mental confusion and restlessness, use Liangge San (Cooling the Diaphragm Powder) to relieve chest oppression, release the exterior, vent toxins, cool blood, resolve toxicity, and clear Fire to eliminate the root cause. It also states: Dryness of the Kidney causes vexation of the Heart, where Fire is constrained by Water and forced outward. The Classics state: For dryness and urgency of the Kidney, pungent foods should be consumed to moisten. The Lung governs vexation, and the Kidney governs dryness. In cases involving Phlegm, Fire, Toxins, Parasites, or Pruritus, herbs such as Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Maidong (Ophiopogonis Radix), Zhimu (Anemarrhenae Rhizoma), Beimu (Fritillariae Bulbus), Lianqiao (Forsythiae Fructus), Cheqianzi (Plantaginis Semen), Lingyangjiao (Saigae Tataricae Cornu), Xijiao (Rhinoceoris Cornu - *Note: Use substitutes due to conservation laws*), Fangfeng (Saposhnikoviae Radix), Dancao (Gentianae Radix), Genge (Puerariae Radix), Donghua (Adenophorae Radix), Fuling (Poria), Chaihu (Bupleuri Radix), Shanzhi (Gardeniae Fructus), Huaihua (Sophorae Flos), Shigao (Gypsum Fibrosum), and Gualouren (Trichosanthis Semen) may be used. Additionally, Xuanshen (Scrophulariae Radix), Sheng Gancao (Glycyrrhizae Radix et Rhizoma), Fuling (Poria), and Shanzhi (Gardeniae Fructus) should be added to clear Lung Fire, preferably in heavy doses, or formulas like Dahuang (Rhei Radix et Rhizoma) and Liuyi San (Six-to-One Powder) may be employed.
