肿胀的成因，大概是因为脾胃元气虚损，又不能调养饮食、起居作息失常，进而再次损伤脾、肺、肾三经，这些都能导致浮肿。损伤脾脏而致肿的，就是《内经》所说的“诸湿肿满，皆属脾土”的道理。损伤肺脏而致肿的，就是《内经》所言：饮食进入胃中，游溢精气，上输于脾，脾气散布精微，上归于肺，通调水道，下输膀胱；若肺脏受伤，不能通调水道、下输膀胱，致使小便不利，水液溢出而形成浮肿。损伤肾脏而致肿的，肾属水，因肾气虚寒不能摄纳气机，以致水液泛滥反而浸渍于上部，于是三焦停滞，经络壅塞，水渗于皮肤，注入肌肉，从而形成浮肿。
脉象浮大的预后良好（生），脉象沉细的预后不良（死）。脐部突出、锁骨上窝平坦、手足心肿胀且无纹理、腹部胀满且青筋暴露、腰部及阴囊肿胀且无皱褶的，都属于难治之症。
治疗方面，伤于脾的，宜用实脾利水、行气的方法。可选用嘉禾散、乌沉散、五加散、实脾散、五苓散、五皮散、平胃散、胃苓散、流气饮等方剂，酌情详细选用。切不可使用樟柳、芫花、黑牵牛子、大戟、甘遂等峻下逐水的药剂。伤于肺的，用补中益气汤加减治疗。肾水虚寒的，用附子理中汤或香砂六君汤加入姜、附煎服，并送服金匮肾气丸。以上各方，关键在于灵活变通运用其奥妙，尤其在于医生能随时取用得当。
瘴疟的发生，多由痰浊阻滞所致。因此病愈后稍有不慎调养，痰证就会发作。然而痰引起的变证，不止一种表现，如嗤笑、咳嗽、呕吐逆气、麻木、痞满隔阻，以及作为异病中最严重的，还有突然暴发的痰厥、眩晕等症状。
如果是痰厥导致的僵仆倒地、不省人事，脉象浮而迟缓的预后良好，脉象数而急疾的预后不良。若出现眼睛睁开或闭合、手撒开、遗尿、吐沫、喉间声音如鼾睡、头发直立、摇头、汗珠如串珠般滴落等症状，都属于不治之症。治疗方面，对于痰厥，可用三生饮合夺命散。若元气不虚者，可选用吹鼻药、三生饮、星附汤、星香散及导痰汤。其他痰证以二陈汤为主，随症状施治，不可拘泥于一法。
The cause of edema and swelling lies generally in the deficiency and damage of the primordial Qi of the Spleen and Stomach. When one fails to regulate diet and daily routine, it further injures the meridians of the Spleen, Lung, and Kidney, all of which can lead to swelling. Swelling caused by injury to the Spleen corresponds to the classic saying: "All dampness, edema, and fullness belong to the Earth (Spleen)." Swelling caused by injury to the Lung corresponds to the classic text: "Food and drink enter the Stomach, their essence floats and overflows, is transported upward to the Spleen, where the Spleen's Qi scatters the essence, sending it upward to the Lung. The Lung regulates the water passages, transporting them downward to the Bladder." If the Lung is injured and cannot regulate the water passages or transport them downward to the Bladder, urination becomes difficult, leading to fluid overflow and swelling. Swelling caused by injury to the Kidney: The Kidney belongs to Water. Due to deficiency and cold of the Kidney Qi, it fails to grasp Qi, causing fluids to overflow and inundate the upper body. Consequently, the Triple Burner stagnates, and the collaterals become obstructed; fluid seeps into the skin and pours into the muscles, resulting in swelling.
A floating and large pulse indicates survival (favorable prognosis), while a deep and fine pulse indicates death (unfavorable prognosis). Umbilical protrusion, flattening of the supraclavicular fossa, swelling of the palms and soles without wrinkles, abdominal distension with exposed blue veins, and swelling of the waist and genitals without folds are all untreatable conditions.
For treatment of Spleen injury, methods should solidify the Spleen, promote diuresis, and move Qi. Jiahe San, Wuchen San, Wujia San, Shipi San, Wuling San, Wupi San, Pingwei San, Weiling San, and Liuqi Yin may be selected according to detailed circumstances. One must strictly avoid using harsh purgative agents such as Zhangliu (Camphor Willow), Yuanhua (Genkwa Flower), Heiqian (Black Morning Glory Seed), Daji (Euphorbia Pekinensis Root), and Gansui (Kansui Root). For Lung injury, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with modifications should be used. For deficiency-cold of Kidney Water, Fuzi Lizhong Tang (Aconite Pill to Regulate the Middle) or Xiangsha Liujun Tang (Aucklandia and Amomum Six-Gentlemen Decoction) decocted with Ginger and Aconite, followed by administering Jin Gui Shenqi Wan (Kidney Qi Pill from the Golden Cabinet), may be used. The key to the above formulas lies in their flexible application; it depends on the physician's ability to utilize them appropriately at any time.
Zhang Nue (Malarial Syndrome due to Miasma) often arises from phlegm obstruction. Therefore, if post-recovery care is slightly negligent, phlegm symptoms will recur. However, the variations of phlegm syndromes are not limited to one type; they manifest as laughter, coughing, vomiting and regurgitation, numbness, epigastric fullness and obstruction, and among the most severe異病 (heterogeneous diseases), sudden phlegm syncope (Tan Jue) and vertigo.
If phlegm syncope leads to rigid collapse and unconsciousness, a floating and slow pulse indicates survival, while a rapid and urgent pulse indicates death. Symptoms such as open or closed eyes, hand relaxation, urinary incontinence, foaming at the mouth, snoring-like sounds in the throat, straightened hair, head shaking, and sweat dropping like pearls are all untreatable conditions. For treatment of phlegm syncope, Sansheng Yin combined with Duoming San may be used. If the primordial Qi is not deficient, nasal insufflation powder, Sansheng Yin, Xingfu Tang, Xingxiang San, and Daotan Tang may be selected. For other phlegm syndromoms, Erchen Tang (Two-Aged Decoction) serves as the main formula, treating according to specific symptoms without adhering rigidly to a single method.
