First paragraph: Summary of content

Bazheng Powder is a classic prescription of traditional Chinese medicine. It is mainly used to clear away heat, purge fire, diuretic and relieve stranguria. It focuses on symptoms such as difficulty urinating, frequent urination and painful urination caused by damp and heat. This article will unfold from the four dimensions of historical origin, medicinal materials, functional principles, and modern applications, focusing on analyzing its main therapeutic function of "clearing away heat and promoting dampness", supplemented by explanations of incompatibility and applicable groups. The whole article is based on "Taiping Huimin Heji Bureau Prescription" as the original document, and is explained in combination with the standards of the modern "Chinese Pharmacopoeia".

Paragraph 2: History and Composition

Bazhengsan was first recorded in the Song Dynasty's official medical code "Taiping Huimin Hejiju Prescription", which consists of eight main herbs:

Mutong	6g
Qumai	9g
萹萹	9g
Plantago	9g
Talc	15g
Gardenia	9g
Rhubarb	6g
Licorice shoots	3g

. Zhang Jingyue, a physician in the Ming Dynasty, particularly emphasized in "Jingyue Complete Book": "The beauty of this prescription lies in clearing away heat and promoting dampness without damaging righteousness." Modern research has confirmed that Qumai in the prescription contains flavonoid glycosides, Plantago seeds contain mucilage and other active ingredients, which work together to exert a synergistic effect.

Paragraph 3: Mechanism of Action

This prescription works through three pathways: 1) Akebia and talc promote diuresis and treat stranguria; 2) Gardenia and rhubarb clear away heat and purge fire; 3) Licorice harmonizes various medicines. Research from the Chinese Academy of Chinese Medical Sciences shows that Bazheng Powder can significantly reduce the levels of IL-6 inflammatory factors in patients with urinary tract infections (p<0.01). It should be noted that the recipe contains aristolochic acid, and the 2020 edition of "Chinese Pharmacopoeia" recommends using Tongcao instead. People with renal insufficiency should use it with caution.

Paragraph 4: Modern Applications

In clinical practice, Bazhengsan is often used for:

acute cystitis	Effectiveness 82.6%
prostatitis	Effectiveness 76.4%
Urinary tract stones	The stone removal rate is 68.9%

(Data source: 2019 "Chinese Journal of Traditional Chinese Medicine"). Professor Wang Qi from Beijing University of Chinese Medicine pointed out: "When using it, treatment should be based on syndrome differentiation. The best indications are those with damp-heat syndrome with red tongue, yellow greasy coating, and short red urine."

Paragraph 5: Summary and Tips

As a prescription that has been proven for thousands of years, Bazheng Powder has clear scientific basis for its core effect of clearing away heat and promoting dampness.
