众所周知，贵州省地处西南高原地区，该地区晴天少、阴雨天多，空气较潮湿，使得类风湿性关节炎成为该省发病率较高的慢性疾病之一。然而，独特的喀斯特地理环境和多变的气候孕育了足具特色的喀斯特地区药用植物，特别是藤类植物如小花清风藤Sabia parviflora，黑骨藤Periploca forrestii，鸡屎藤Paederia scandens (Lour. ) Merr.，清风藤Sinomenium acutum (Thunb.)等，这些药用植物多具有祛风除湿、消肿止痛等功效。其中，小花清风藤作为贵州布依族、苗族重要的民族药，主要分布在贵州省黔西南州兴义市、安龙县、册亨县、望谟县等地[5, 6]。在喀斯特地貌地区，小花清风藤喜生相对阴湿的环境，生长于黑色石灰石土壤中，如石沟、岩石隙或者砂石山中[7]。在民间，小花清风藤叶用作治疗类风湿关节炎等疾病的良药，效果显着，

As everyone knows, Guizhou is located in the southwest plateau. In this area, it is sunny, rainy and rainy, and the air is humid. It makes rheumatoid arthritis a chronic disease with high incidence rate in this province. However, the unique karst geographical environment and changeable climate gave birth to the unique medicinal plants in karst areas, especially the rattan plants such as Sabia parviflora, Periploca forrestii, Paederia scandens (Lour.) Merr., Sinomenium acutum (Thunb.) and so on. Most of these medicinal plants have the functions of dispelling wind and dehumidification, detumescence and pain relief.
