Dribbling urine, red color, and dysuria are all caused by internal heat; it is appropriate to use methods to clear heat and promote urination.
Urinary retention is due to unfavorable Qi movement. Deficiency of Qi leads to stagnant Qi flow; deficiency of Blood leads to failure of Qi to ascend. Excess phlegm obstructs Qi transport.
Treatment principles: Tonify Qi for Qi deficiency, nourish Blood for Blood deficiency, and guide out phlegm for excess phlegm. First administer the corresponding base medicine, then employ emesis to lift the Qi.
Once the Qi ascends, water naturally flows downward; this can be supplemented with Wuling San (Five-Ingredient Poria Decoction).

Ingredients: Phellodendri Cortex (Huangbai, wine-fried), Anemarrhenae Rhizoma (Zhimu, wine-fried, 1 qian), Cinnamomi Ramulus (Gui, a small amount). If blood stasis causes Qi obstruction, or if dead blood causes lin syndrome, add Talcum (Huashi), Poria (Fuling), and Alismatis Rhizoma (Zexie).
Niuxi Gao (Achyranthes Bidentata Paste): Treats lin syndrome caused by dead blood (blood stasis).
Mr. Li’s treatment method: Heat in the Upper Jiao is primarily treated with Gardeniae Fructus (Zhizi) and Scutellariae Radix (Huangqin); for the Middle Jiao, add Coptidis Rhizoma (Lian) and Paeoniae Radix Alba (Shaoyao); for the Lower Jiao, add Phellodendri Cortex (Huangbai); for hot lin syndrome, promote diuresis using Gardeniae Fructus (Zhizi) and similar herbs; for Qi deficiency, use Ginseng Radix et Rhizoma (Renshen) and Atractylodis Macrocephalae Rhizoma (Baizhu) plus Akebiae Caulis (Mutong).
For urinary difficulty: For Qi deficiency, use Ginseng Radix et Rhizoma (Renshen) and Atractylodis Macrocephalae Rhizoma (Baizhu) plus Cimicifugae Rhizoma (Shengma), followed by emesis; for Blood deficiency, use Siwu Tang (Four-Substance Decoction), followed by emesis; for phlegm-Qi stagnation, use Erchen Tang (Two-Aged Decoction) plus Akebiae Caulis (Mutong) and Cyperi Rhizoma (Xiangfu), followed by emesis.
For lin syndrome caused by the Three Causes:
