Medicinal plants are the primary sources of healthcare among the people of developing countries in villages and local towns. Documenting and reporting the traditional knowledge of medicinal plants may contribute to pharmaceutical research development. For this reason, we present our findings on ethnomedicinal plants from Lingchuan County, Shanxi, China, an unexplored area rich in medicinal plant resources. Information of ethnomedicinal plants were collected through questionnaire/semi-structured interviews from 180 informants, including traditional healers. Field surveys were conducted in 53 villages of Lingchuan County from 2017 to 2018. Informed consent was obtained from each participant before conducting the interview process. Quantitative analysis was performed for each recorded species, such as Relative Frequency Citation (RFC), Use Value (UV), and Factor of Informant Consensus (FIC). Diseases were categorized into twelve groups. A total 138 species of medicinal plants were recorded, belonging to 123 genera of 58 families. Asteraceae was the dominant plant family with 19 species, followed by Rosaceae and Fabaceae. Herbs were dominant among plant life-forms with 96 species, followed by shrubs and trees (15 species each). Roots were the most commonly used plant parts with 58 species, followed by whole plants and fruits (28 species each). Most plant species were reported non-toxic (84, 60%), followed by unknown toxicity (35, 25%), poisonous, and less toxic (19, 14%). Quantitative analysis revealed that Forsythia suspensa was with higher (0.33) RFC value, and Scutellaria baicalensis was recorded with a higher (0.91) UV. Treated diseases were categorized in 12 groups and evaluated by their FIC value, in which gynecological diseases have higher (0.93) FIC value followed by urinary system diseases. Most medicinal plants are used to clear away heat and relieve the surface. The present study revealed that local people of Lingchuan County confidently use ethnomedicinal plants for their healthcare needs. The higher indices value of a plant species resulted from quantitative analysis warrants further investigation, which may possess valuable phytochemical compounds that may result in new drugs for treating various human disorders.
药用植物是发展中国家农村和当地城镇民众医疗保健的主要来源。记录和报告药用植物的传统知识可能有助于药物研发。基于此，我们呈现了来自中国山西灵川县的药用植物民族医学研究结果，该县是一个尚未开发的药用植物资源丰富的地区。通过对 180 名信息提供者（包括传统医生）的问卷调查/半结构化访谈收集了药用植物民族医学的信息。2017 年至 2018 年，在灵川县的 53 个村庄进行了实地调查。在进行访谈过程之前，我们获得了每位参与者的知情同意。对每种记录的物种进行了定量分析，如相对频率引用（RFC）、使用价值（UV）和信息提供者共识因子（FIC）。疾病被分为十二组。共记录了 138 种药用植物，属于 58 科 123 属。菊科是优势科，有 19 种，其次是蔷薇科和豆科。草本植物在植物生活型中占主导地位，有 96 种，其次是灌木和乔木（各有 15 种）。根是最常用的植物部位，有 58 种，其次是全株和果实（各有 28 种）。大多数植物物种被报道为无毒（84，60%），其次是毒性未知（35，25%）、有毒和毒性较小（19，14%）。定量分析显示，连翘的 RFC 值较高（0.33），黄芩的 UV 值较高（0.91）。治疗的疾病分为 12 组，并根据其 FIC 值进行评估，其中妇科疾病的 FIC 值较高（0.93），其次是泌尿系统疾病。大多数药用植物用于清热解表。本研究表明，灵川县当地居民自信地使用民族药用植物来满足他们的医疗保健需求。植物物种的较高指数值源于定量分析，值得进一步研究，因为这些植物可能含有有价值的植物化学化合物，可用于治疗各种人类疾病的新药。
