Abstract： Objective： Based on data mining technology， to explore the point selection rules of acupuncture and moxibustion for adults with psoriasis vulgaris. Methods： Clinical research literature on acupuncture and moxibustion for adults with psoriasis vulgaris from January 2002 to January 2022 was retrieved from China National Knowledge Internet，Wanfang Data Knowledge Platform，VIP Journal Fulltext Database and China Biology Medicine disc. The clinical literature database was established and the characteristics of point selection were analyzed. Data mining software such as SPSS Statistic26.0 and SPSS Modeler14.0 were used for descriptive analysis，association rule analysis and cluster analysis. Results：In the end，71 pieces of clinical research literature were included and 112 point prescriptions were collected， involving 73 acupuncture points. The top three treatment methods were acupuncture， fire needling and bloodletting puncture and cupping therapy. The top five acupuncture points used frequently were Feishu point (BL 13)，Geshu point (BL 17)，Quchi point (LI 11)，Xuehai point (SP 10) and Ganshu point (BL 18)， with back-shu point being the most frequently used in specific points. The top three meridians used frequently were bladder meridian， spleen meridian and large intestine meridian. Association rule analysis showed that two-line association group with the highest support was Feishu point (BL 13)- Pishu point (BL 20)，the three-line association group was Quchi point (LI 11)-Sanyinjiao point (SP 6) - Xuehai point (SP 10)， and the four-line association group was Feishu point (BL 13)-Shenshu point (BL 23) - Pishu point (BL 20) - Ganshu point (BL 18). Cluster analysis of the acupuncture points with a frequency of use higher than five allowed the points to be classified into three major categories. The first category is Ashi point. The second category can be divided into two groups，Baihui point (DU 20)，Waiguan point (SJ 5) and Weizhong point (BL 40) as one group，and Xinshu point (BL 15)，Feishu point (BL 13)，Geshu point (BL 17)，Ganshu point (BL 18)，Pishu point (BL 20) and Shenshu point (BL 23) as one group. The third category can be divided into two groups，Yinlingquan point (SP 9) as one group， and the rest of the points as one group， including Quchi point (LI 11)，Sanyinjiao point (SP 6) and Xuehai point (SP 10)，etc.. Conclusion：The application of acupuncture and moxibustion for adults with psoriasis vulgaris often take the methods including acupuncture， fire needling and bloodletting puncture and cupping therapy. The main points selected are transport point combined with traditional point groups for skin diseases. The points are mainly from the bladder meridian， spleen meridian， large intestine meridian， which can provide reference for the clinical use of acupuncture and moxibustion in the treatment of adults with psoriasis vulgaris.
