Effect of Astragali Radix Membranaceus in Promoting Blood Circulation and Its Modern Pharmacology Research / 中国实验方剂学杂志

ABSTRACT

Astragali Radix membranaceus is first recorded in Shennong Bencaojing, which has the effect in replenishing Qi and rising Yang, strengthening the body surface resistance, inducing diuresis to alleviate edema, and supporting for detoxication and tissue generation. As an essential medicine for invigorating Qi and invigorating the spleen, it is often used in diseases, such as Qi deficiency and fatigue, spleen deficiency diarrhea and so on, and has been well known by doctors. In recent years, scholars have a comprehensive understanding of the mechanisms in replenishing Qi, invigorating spleen and promoting water. However, Tao Hongjing first recorded that Astragali Radix membranaceus can " clear the evil blood between the five organs" . In Bencaojing Jizhu, this herbal medicine has the effect in promoting blood circulation at the same time. At present, traditional Chinese medicine often explains the mechanism of this herbal medicine in promoting blood circulation based on the theory of " replenishing Qi and activating blood circulation" and " blood circulation due to Qi circulation" , which however is not equivalent to the fact that this herbal medicine has no blood circulation effect. By summarizing the records of Astragali Radix membranaceus in the herbal literatures of the previous dynasties, it was found that its promoting blood circulation effect was widely used. In summary of the applications of traditional prescriptions and modern prescriptions in promoting blood circulation, Astragali Radix membranaceus can remove obstruction and activate blood circulation, activate blood and promote diuresis, activate blood circulation and strengthen the body resistance, which can best reflect the effect in activating blood circulation of this medicine. Modern pharmacology shows that Astragali Radix membranaceus has a good regulatory effect on the molecular mechanism of blood stasis pathological indexes by activating blood circulation. Due to no in-depth research, there is still room for study. Therefore, this paper thoroughly explores the mechanism of action of Astragali Radix membranaceus in promoting blood circulation by summarizing the effects of Astragali Radix membranaceus in literatures of previous dynasties and modern pharmacological studies, in order to expand the clinical application of Astragali Radix membranaceus and provide theoretical guidance for clinical treatment.
