Treats fire in the Small Intestine, presenting with red and painful dysuria (painful urinary frequency), flushed face, mania and restlessness, oral ulcers and lingual sores, teeth grinding, and thirst. (The Heart and Small Intestine are interior-exteriorly related; heat in the Heart leads to heat in the Small Intestine, hence red and painful dysuria. The Heart belongs to Ministerial Fire (Jun Huo), which is the master of fire in the five zang and six fu organs; thus, heat from all meridians responds to the Heart: a flushed face, restlessness, teeth grinding, and thirst are all manifestations of Heart Heat. The tongue is the sprout of the Heart; if Heart Fire flares upward and steams the mouth, it causes oral ulcers and lingual sores. Heat felt upon light palpation between the skin and muscle, especially severe at noon, indicates heat in the blood vessels, belonging to Heart Heat. Zhu Danxi said: Each of the five zang organs has its own fire; when stirred by the five emotions, the fire arises accordingly.)
Shengdi Huang (Rehmanniae Radix Preparata), Mutong (Akebiae Caulis), Gancao Shao (Glycyrrhizae Radix et Rhizoma - tip), and Dan Zhuye (Lophatheri Folium) in equal parts. Decoct and take.
These are herbs for the Hand Shaoyin (Heart) and Hand Taiyang (Small Intestine) meridians. Sheng Di Huang cools blood and nourishes Heart Blood; Dan Zhu Ye clears Heart Qi (since leaves grow on bamboo, it clears the Upper Jiao); Mutong descends Heart Fire and enters the Small Intestine (Ministerial Fire is suited to Mutong, while Damp-Heat Fire is suited to Zexie; although both promote urination, their applications differ. Jun refers to Heart Fire; Xiang refers to Kidney Fire); Gancao Shao reaches the urethra to relieve pain (addressing red and painful dysuria). Together, they guide Bing-Ding Fire (Small Intestine is Bing Fire, Heart is Ding Fire) out through the urine. (Clearing Heart Heat via the Small Intestine embodies the principle of "drawing firewood from under the cauldron." Yi Lao combined Dao Chi San with Wu Ling San to treat oral ulcers with excellent effect. The Classic states: When bladder heat transfers to the small intestine, causing obstruction of the diaphragm and intestines, it manifests upward as oral ulcers. There are also cases using Li Zhong Tang plus Fuzi, because fire due to Spleen-Stomach deficiency and collapse is forced upward; thus, Renshen, Baizhu, and Gancao tonify Earth, while Ganjiang and Fuzi disperse cold, allowing the fire to be assisted and retreat. Compendium of Materia Medica states: When Heart Qi is hot, fire rushes upward, suitable for Dao Chi San; when Kidney Qi is deficient, fire rushes downward...)

Treats fever and restlessness caused by worry and depression; or excessive alcohol and food intake leading to excessive fire suppressing Metal, resulting in bitter taste in the mouth, dry throat, gradually developing into Xiao Ke (Wasting-Thirst), spermatorrhea, turbid and painful urination, recurring upon exertion, limb fatigue, five-palm heat (heat in the palms, soles, and chest), worse at night but quiet during the day; and in women, metrorrhagia and leukorrhea. (Restlessness, spermatorrhea, and dysuria indicate Heart Deficiency with Heat; when Heart Fire moves recklessly, it cannot descend to communicate with the Kidney, causing loss of Yuan Jing (Essence). Recurrence upon exertion is called Lao Lin (Exhaustion Dysuria), as exertion stirs Heart Fire. Heat predominating during the day indicates Yang Deficiency. Metrorrhagia results from damage to the Chong and Ren vessels, with both Qi and Blood deficient. The Classic states: Yin deficiency with Yang pounding is called Beng (Metrorrhagia). Due to Yin deficiency and Yang pounding, blood moves recklessly due to heat. Leukorrhea derives its name from the Dai Mai (Girdle Vessel); red indicates Blood involvement, white indicates Qi involvement, stemming from Yin deficiency and Yang exhaustion, where Ying Qi fails to ascend and Wei Qi sinks...)
Shi Lian Rou (Nelumbinis Semen), Renshen (Ginseng Radix), Huangqi (Astragali Radix), Fuling (Poria), Chaihu (Bupleuri Radix - 3 qian), Huangqin (Scutellariae Radix, stir-fried), Digupi (Lycii Cortex), Maidong (Ophiopogonis Radix), Cheqianzi (Plantaginis Semen), and Gancao (Licorice Root) in appropriate amounts.
These are herbs for the Hand Shaoyin (Heart), Foot Shaoyang (Gallbladder), and Foot Taiyin (Spleen) meridians. Renshen and Gancao tonify Yang Deficiency and drain fire (Li Dongyuan stated: Renshen and Gancao are the holy medicines for draining fire), assist Qi transformation to reach the Zhou Du (Bladder; when Qi transforms, urination occurs); Digupi retreats deficiency heat from the Liver and Kidney; Chaihu disperses fire pathogens from the Liver and Gallbladder; Huangqin and Maidong clear heat from the Heart, Lungs, and Upper Jiao; Fuling and Cheqianzi promote dampness drainage in the lower Bladder region; Shi Lian Rou in the middle clears Heart Fire and facilitates communication between the Heart and Kidney, thereby resolving all symptoms.
