Xuanfu Daizhe Decoction: a classic prescription to harmonize the spleen and stomach, reduce phlegm and reduce phlegm.

Xuanfu Daizhe Decoction is one of the classic prescriptions of traditional Chinese medicine. It comes from "Treatise on Febrile Diseases" and was created by Zhang Zhongjing. It is mainly used to treat symptoms such as belching, vomiting, and hardness in the heart caused by stomach deficiency and phlegm obstruction and qi reversal. This article will focus on the four aspects of prescription composition, efficacy mechanism, clinical application and modern research. It will focus on analyzing its core functions of harmonizing the spleen and stomach, reducing phlegm and reducing phlegm. It will also be supported by ancient and modern medical records to help readers fully understand the practical value of this prescription.

Essentials of prescription composition and compatibility

Xuanfu Daizhe Decoction uses Inula and Daizhi as the king herbs, and is combined with ginseng, ginger, pinellia, licorice, and jujube. It has the effect of reducing phlegm, replenishing qi, and harmonizing the stomach. Inula is warm in nature, good at lowering qi and eliminating phlegm; it replaces the heavy sedimentation of ocher and specializes in relieving negative qi; ginseng nourishes qi and replenishes qi, ginger warms and relieves vomiting, pinellia dries dampness and resolves phlegm, and licorice and jujube harmonize various medicines. The combination of seven medicines not only attacks evils but also strengthens health, which embodies Zhang Zhongjing's prescription thinking of "applying both attack and tonic".

Analysis of efficacy mechanism and indications

This prescription is mainly used to treat "hardness in the heart and unresolved gas". Its pathogenesis is weakness of the spleen and stomach, phlegm obstruction, and stomach Qi ascending. In modern times, it is often used for patients with reflux esophagitis, chronic gastritis and other syndromes of stomach deficiency and phlegm obstruction. Clinical studies have shown that Xuanfu Daizhe Decoction can regulate gastrointestinal motility and inhibit gastric acid secretion. The ferric oxide contained in Xuanfu Daizhe Decoction also has a sedative effect on the central nervous system. It should be noted that due to ocher-induced sedimentation, pregnant women and those with mid-air depression should use it with caution.

Ancient and modern medical records and extension of modern applications

Ye Tianshi, a famous doctor in the Qing Dynasty, used this prescription to treat "choking" (similar to modern esophageal cancer), emphasizing that the dosage of pinellia and ocher should be adjusted according to the severity of phlegm and dampness. In modern clinical practice, it also has significant effects on vomiting and neurological hiccups after chemotherapy. Experimental data shows that Inula flower extract can inhibit Helicobacter pylori, while ocher decoction can repair gastric mucosal damage, confirming the scientific value of the ancient prescription.

Summary: inheritance and innovation of classic prescriptions

Xuanfu Daizhe Decoction has been proven for thousands of years. Its characteristics of "reducing qi without damaging the qi, resolving phlegm and replenishing deficiency" are still the representative prescription for treating stomach qi qi. Modern research provides scientific basis for traditional efficacy through pharmacological analysis and clinical comparison. When using it, the principles of syndrome differentiation and treatment should be followed, and the compatibility should be adjusted based on specific symptoms to achieve the best effect. This prescription vividly demonstrates the wisdom of traditional Chinese medicine in "treating different diseases with the same treatment".
