瘥后有声不能言，此水亏不能上接于阳也。
郑声者，声战无力，语不接续，乃气虚也。
瘥后喜唾不能自止者，胃中有寒也，宜温之。热病愈后吐津不止，虽属胃虚，犹有余热，不宜温之，
只用梅枣丸噙之立愈。
言者心之声也。病中谵妄，乃胃热乘心；瘥后多言者，犹有余热也。譬如灭火，其火已息，尚有余烟。
瘥后触事易惊，梦寐不宁，乃有余热；热极生痰，痰与气搏，故恐惧。
心之所藏，在内为血，在外为汗。汗者心之液也，而肾主五液，故汗症未有不从心、肾而得者。阳虚不
能卫外而为固，则外伤而自汗；阴虚不能内营而退藏，则内伤而盗汗。
病后饮食逐渐增加，但大便有时十天、半个月不解，也不觉得痛苦。这是因为热病导致肠胃干燥，血液不能滋润，气机不能推动。
如果误用通利泻下的药物，病人不到一天就会死亡。
毒火最重的病症，气血被其煎熬。病后饮食逐渐恢复，气血滋生，流窜于皮肤并灌注全身百骸，出现或痛或痒，宛如虫行的感觉，这是最好的境界，不过两三天，气血流通自然痊愈。
疫病如果在前期失治，热邪流注下部，阻滞于经络，导致腰膝疼痛，严重的甚至无法站立，卧床不能活动。如果误当作痿证治疗，必然成为废人。（经验之谈）
病后不想吃东西，即使吃了也不能消化，这是脾胃虚弱，应当健脾养胃。
郑声（语声低微重复），声音颤抖无力，话语不连贯，这是气虚的表现。
病后喜欢吐口水且不能自止的，是胃中有寒，应当温补。热病痊愈后吐津不止，虽然属于胃虚，但还有余热，不宜温补，只用梅枣丸含服即可立即痊愈。
言语是心的外在表现。病中胡言乱语，是胃热乘袭心脏；病后多言，是因为还有余热。就像灭火一样，火已经熄灭，但还有余烟。
精的主宰在心，精的封藏制约在肾。病后心肾气虚，不能管理摄持，所以发生遗精。
病后接触事物容易惊吓，睡眠不安宁，是因为有余热；热极生痰，痰与气相搏结，所以产生恐惧感。
整天昏昏沉沉不醒，或者错语呻吟，这是因为邪热未尽，伏留于心包络所致。
心的所藏，在内为血，在外为汗。汗是心的体液，而肾主管五液，所以汗症没有不从心和肾而来的。阳虚不能卫护体表而固密，则受外伤而自汗；阴虚不能内营而退藏，则受内伤而盗汗。
After recovery, food intake gradually increases, but bowel movements may not occur for ten days or half a month, without causing discomfort. This is due to dryness of the intestines and stomach caused by febrile disease, where blood fails to moisten and Qi fails to propel.
If purgatives are mistakenly used, death will occur within a day.
In cases with the heaviest toxic fire, Qi and Blood are scorched. As food intake recovers after illness, Qi and Blood generate and circulate through the skin and permeate the entire body, causing sensations of pain or itching, resembling insects crawling. This is an auspicious sign; within two or three days, as Qi and Blood flow smoothly, self-healing occurs.
If epidemic disease is mismanaged in the early stage, heat flows downward and stagnates in the meridians, leading to pain in the waist and knees. In severe cases, the patient cannot stand or move while lying down. Mistaking this for Wei Syndrome (flaccidity syndrome) will inevitably result in permanent disability. (Clinical Experience)
After recovery, there is a lack of appetite, and even if food is consumed, it is not digested. This indicates Spleen and Stomach deficiency, requiring methods to strengthen the Spleen and nourish the Stomach.
After recovery, Blood deficiency causes the Liver to lose its nourishment, and the Gallbladder loses its support, manifesting as timidity and palpitations.
After illness, Water declines and Fire flares up, leading to a failure of communication between the Heart and Kidney, resulting in restlessness and agitation.
Hoarseness or inability to speak after illness is due to Yin deficiency failing to ascend and connect with Yang.
Zheng Sheng (feeble, repetitive speech) characterized by trembling, weak voice and disjointed sentences indicates Qi deficiency.
Excessive salivation that cannot be controlled after illness indicates Cold in the Stomach, requiring warming therapy. However, excessive saliva secretion after the resolution of febrile disease, although related to Stomach deficiency, still involves residual Heat; warming therapy is contraindicated. Instead, Mei Zao Wan (Plum and Jujube Pill) should be held in the mouth for immediate relief.
Speech is the voice of the Heart. Delirium during illness is caused by Stomach Heat invading the Heart; excessive talking after recovery is due to residual Heat. It is like extinguishing a fire: although the flames have died out, smoke remains.
The Heart governs Essence, and the Kidney stores and controls it. After illness, deficiency of Qi in the Heart and Kidney leads to a loss of control, resulting in seminal emission.
Easily startled by events and restless sleep after illness indicate residual Heat; extreme Heat generates Phlegm, which clashes with Qi, causing fear.
Constant drowsiness, confusion, or moaning is caused by incomplete elimination of pathogenic Heat, which lies latent in the Pericardium Meridian.
The Heart stores Blood internally and manifests as Sweat externally. Sweat is the fluid of the Heart, and the Kidney governs the Five Fluids. Therefore, sweat disorders always originate from the Heart and Kidney. Yang Deficiency fails to defend the exterior and secure the surface, leading to spontaneous sweating upon external injury; Yin Deficiency fails to nourish the interior and store essence, leading to night sweats upon internal injury.
