This article will start from the prescription composition, efficacy principle, applicable population and precautions, and systematically introduce the clinical application value of this traditional famous prescription.

Prescription composition and compatibility principles

Dabuyin Pills byRehmannia glutinosa, turtle shell, cork, and anemarrhenaIt is composed of four medicinal herbs, supplemented by refined honey from pig spinal cord to make pills. Rehmannia glutinosa and tortoise shell nourish yin and replenish essence, while Phellodendron and Anemarrhena purify and release the mutual fire, forming a compatibility characteristic of "taking both specimens into consideration". Zhu Danxi, a physician in the Ming Dynasty, put forward the theory of "Yang is always in excess and Yin is often insufficient" in "Danxi Heart Method". This formula is the embodiment of his academic thoughts. Modern research shows that Cortex Phellodendri in the prescription contains berberine, which has anti-inflammatory effects, while the tortoise shell is rich in collagen, which can promote tissue repair.

Clinical applications and indications

Research from Beijing University of Chinese Medicine shows that when used in combination with anti-tuberculosis drugs, the relief rate of patients' cough and hemoptysis symptoms increases by about 25% (data source: "Chinese Journal of Integrated Traditional Chinese and Western Medicine" 2021 issue). However, people with spleen and stomach deficiency should use it with caution as adverse reactions such as diarrhea may occur.

Precautions and contraindications for use

During the period of takingAvoid spicy and hot food, such as pepper, mutton, etc., so as not to help fire and damage yin. It is recommended to take 2 times a day, 6-9 grams each time, with warm water. Note: ① Stop using it when you have a cold or fever; ② Use it in combination with western antibiotics at an interval of 2 hours; ③ Halve the dosage for children. "Yi Zong Jin Jian" of the Qing Dynasty particularly emphasized that "it is suitable for those with severe deficiency of true yin, but not suitable for those with weak deficiency and strong fire", pointing out that it needs to be used strictly based on syndrome differentiation. Modern pharmacological experiments have confirmed that overdose may lead to abnormal liver function indicators (the incidence of ALT elevation is about 3%).

Summary and scientific understanding

As a representative formula for nourishing yin and reducing fire, Dabuyin Pill embodies the therapeutic idea of "strengthening water to control sunlight" in traditional Chinese medicine. Its advantage is to improve chronic symptoms related to yin deficiency constitution, but it needs to be used under the guidance of a physician. It is worth noting that TCM syndrome differentiation needs to be combined with Western medicine diagnosis. For example, if low-grade fever persists, organic diseases such as tumors must be ruled out. Only by maintaining a regular schedule, exercising moderately, and taking medication can the conditioning effect of "Yin Ping Yang Secret" be better exerted.
