淋证（以小便频数短涩、滴沥刺痛为主症的病证）的成因各不相同：有的因房事过度，有的因愤怒，有的因饮用烈酒或食用浓味厚腻食物。房劳过度者，属于阴虚火旺；愤怒者，气机逆乱而生痛，疼痛剧烈难以忍受。初期表现为热淋（湿热蕴结下焦所致的小便灼热刺痛）、血淋（湿热伤络所致的小便带血），宜采用清热散热、通利小便的方法；日久则煎熬水液，尿液变得浑浊如膏脂，或形成砂粒、结石，宜采用开郁行气、活血化瘀、滋阴的方法。
凡是小肠有气滞，小便就会胀满；小肠有瘀血，小便就会涩滞不畅；小肠有热邪，小便就会疼痛。此时禁用补气的方剂。
膀胱是津液汇聚的府库，依靠气化作用排出尿液。寒邪客居于胞中（此处指下焦泌尿生殖区域），导致气化功能失常而形成淋证，必定先出现寒战，随后小便涩滞频数，伴有中焦肿痛。这是因为冷气侵入胞中，与正气相互抗争，寒气占优势时，就会发生寒战并引发淋证，宜采用散寒扶正的方法。（淋证大多由心肾气郁、清浊之气相干扰，以及热邪蓄积于膀胱所致；因冷气阻滞于膀胱而引发淋证的情况，非常少见。）
虚淋（因肾虚导致的淋证），是肾虚精败的表现。少年时期精气尚未充盈就进行房事，老年人阴气已衰却仍思欲色，导致精气无法排出而在体内腐败败坏，尿道涩痛形成淋证，只有金匮肾气汤可以救治。如果精气已经枯竭还继续耗损，就会导致大小便牵引作痛。
痈疽（泛指体表化脓性感染）病症有五善七恶，不可不加以辨别。凡是饮食知味，动静休息自然安宁，这是第一善。二便调匀，或者稍微干涩，这是第二善。脓液溃破后肿胀消退，脓液新鲜且不臭，这是第三善。神采精明，语声清亮，肌肉好坏界限分明，这是第四善。身体气息平和，这是第五善。
七恶的表现是：烦躁不安，时时咳嗽，腹痛，极度口渴，眼角分泌物多，腹泻痢疾，小便像淋证一样涩痛，这是第一恶。气息微弱连绵，脉象与病情相反，脓血已泄但肿胀更加严重，脓液颜色臭败，疼痛剧烈不可触碰，这是第二恶。目光不正，黑眼球紧缩变小，这是第三恶。呼吸短促，嗜睡，面色青，嘴唇黑，疮疡未溃破时肉色发黑且凹陷，这是第四恶。肩背四肢活动不便，疮疡已溃破后呈青黑色，筋腐骨黑，这是第五恶。饮食不下，服药即呕吐，气噎痰塞，身体寒冷，自汗出，这是第六恶。声音嘶哑，神色败坏，嘴唇鼻子青赤，面目及四肢浮肿，这是第七恶。
Lín zhèng (a syndrome characterized by frequent, short, and scanty urination with dribbling, stinging pain) has various causes: some result from excessive sexual activity, some from anger, and some from consuming strong alcohol or rich, heavy foods. Excessive sexual activity leads to Yin deficiency with hyperactive fire; anger causes Qi rebellion generating pain that is severe and unbearable. In the early stage, it manifests as Rè lín (heat strangury caused by damp-heat accumulating in the lower jiao) or Xuè lín (blood strangury caused by damp-heat injuring collaterals), which should be treated with methods to clear heat, dissipate heat, and promote diuresis. If prolonged, the fluids are scorched, becoming turbid like paste or forming sand-like stones, requiring methods to open stagnation, move Qi, break blood stasis, and nourish Yin.
When there is Qi stagnation in the Small Intestine, urination becomes distended; when there is Blood stasis in the Small Intestine, urination becomes obstructed and unsmooth; when there is Heat in the Small Intestine, urination becomes painful. At this time, Qi-tonifying formulas are strictly contraindicated.
The Bladder is the mansion of body fluids, relying on Qi transformation for excretion. When Cold pathogen lodges in the Bao Zhong (lower jiao urogenital region), Qi transformation fails, leading to strangury. This typically presents first with chills, followed by obstructed, frequent urination accompanied by mid-abdominal swelling and pain. This occurs because Cold Qi enters the Bao, contending with Healthy Qi; when Cold dominates, chills occur and strangury develops. The treatment should focus on dispersing Cold and supporting Healthy Qi. (Most cases of strangury are caused by Qi stagnation in the Heart and Kidney, interference between Clear and Turbid Qi, and Heat accumulation in the Bladder; cases caused solely by Cold Qi stagnation in the Bladder are rare.)
Xū lín (deficiency strangury) is a manifestation of Kidney deficiency and essence deterioration. If young men engage in intercourse before their Essence is fully developed, or if elderly men, whose Yin energy has already declined, still indulge in lust, the Essence cannot exit but rots internally, causing stinging pain in the penis and forming strangury. Only Jinkui Shenqi Tang (Kidney Qi Pill from the Golden Cabinet) can rescue such conditions. If Essence is already exhausted but continues to be depleted, it will cause pulling pain during defecation and urination.
Yong Ju (boils and carbuncles, general terms for superficial suppurative infections) present with Five Good Signs and Seven Bad Signs, which must not fail to be distinguished. Eating with taste and resting naturally without agitation is the First Good Sign. Regular bowel movements and urination, or slight dryness/astringency, is the Second Good Sign. After pus discharges and swelling subsides, with fresh, non-foul-smelling discharge, is the Third Good Sign. Bright spirit, clear voice, and distinct demarcation between healthy and unhealthy flesh is the Fourth Good Sign. Harmonious body breath and calmness is the Fifth Good Sign.
The Seven Bad Signs are: restlessness, frequent coughing, abdominal pain, extreme thirst, excessive eye discharge, diarrhea/dysentery, and painful, strangury-like urination—this is the First Bad Sign. Faint, continuous breathing, pulse contradicting the disease, continued swelling after pus/blood discharge, foul-smelling pus, and unbearable pain upon touch—this is the Second Bad Sign. Misaligned gaze and tight, small black pupils—this is the Third Bad Sign. Shortness of breath, lethargy, blue complexion, black lips, black flesh with depression before ulceration—this is the Fourth Bad Sign. Inconvenience in shoulders, back, arms, and legs; after ulceration, dark green/black color, rotting sinews, and black bones—this is the Fifth Bad Sign. Inability to eat, vomiting after taking medicine, Qi obstruction with phlegm blockage, cold body, and spontaneous sweating—this is the Sixth Bad Sign. Hoarse voice, ruined complexion, blue-red lips and nose, and edema of face, eyes, and limbs—this is the Seventh Bad Sign.
Yong (boil) is superficial and large; when Heat dominates, it transforms into pus. Ju (carbuncle) is deep and malignant.
Yang (ulcer/sore) refers to a sore with a head. Zhen (rash) refers to floating, small nettle-rashes (Heat dominating Yin results in sores/ulcers; Dampness stagnating in Blood results in nettle-rashes).
