Conditions
Pueraria plays a significant role in enhancing the intestinal absorption of several key active compounds. Specifically, it promotes the absorption of baicalin, with its effect being particularly obvious. The plant also facilitates the absorption of wogonoside, even though other components like Glycyrrhiza may act differently. Additionally, Pueraria is shown to promote the absorption of liquilitin. Finally, it works alongside Glycyrrhiza to improve the absorption of jateorhizine and berberine.
Preparations
Pueraria is prepared as Baoji pills, a complex traditional Chinese medicine whose quality can be evaluated using HPLC-DAD fingerprint analysis. It is also prepared as Ganmao Qingre Granules, which are used to determine puerarin levels through RP-HPLC methods. Additionally, Pueraria is prepared as a spray for intranasal administration, allowing for the study of its pharmacokinetic features in rabbits. The plant is further prepared as Yufeng Ningxin Tablets, which can be analyzed using a pueraria reference extractive substance in beagle plasma. Finally, Pueraria is prepared as an extract that has been shown to ameliorate alcoholic liver disease by regulating gut microbiota.
Parts used
Pueraria is a versatile medicinal and edible plant that offers significant health benefits through its various anatomical parts. The tuberous root is highly valued in the pharmaceutical industry, particularly for its potential antidepressant effects and its rich concentration of nutrients and medicinal components. Research also indicates that the stems possess a chemical composition similar to the roots, suggesting they could serve as a viable substitute resource. Furthermore, extracts derived from the flower are utilized in functional foods and have been studied for their impact on visceral fat and enzymatic activities. Collectively, the root, stem, and flower of Pueraria provide a wide range of bioactive compounds for diverse therapeutic applications.
