Ancient and Modern Evolution and Causes of Medicinal Properties of Xuanfuhua(Inulae Flos)
The evolution of the medicinal properties of Xuanfuhua(Inulae Flos)was studied from four qi,five flavors,meridian tropism,and ascending,descending,floating,sinking,etc.The causes of different understandings of the medicinal properties of Xuanfuhua in the records were preliminarily explored.The theory of medicinal properties of Xuanfuhua was established in Shennong's Classic of Materia Medica and Miscellaneous Records of Famous Physicians,based on which the literature of materia medica in the past dynasties were expanded.After the Sui and Tang Dynasties,the clinical application of Xuanfuhua was expanded,and it was used to treat diseases of head and face.The long-term understanding of"specific property of descending"of Xuanfuhua was broken in the Song Dynasty,and the medicinal properties were explained from the perspective of bitter and acrid in flavor and dispersing in nature.In the Ming and Qing Dynasties,there were diversified understandings of"specific property of descending","ascending and descending",and"rotation in nature".The species of Xuanfuhua in ancient medical books were different,the medication parts were not unified,and the clinical compatibility changes were rich.All the above factors might have an impact on the determination of medicinal properties.
