Studies suggesting that medicinal plants are not chosen at random are becoming more common. The goal of this work is to shed light on the role of botanical families in ethnobotany, depicting in a molecular phylogenetic frame the relationships between families and medicinal uses of vascular plants in several Catalan-speaking territories. The simple quantitative analyses for ailments categories and the construction of families and disorders matrix were carried out in this study. A Bayesian approach was used to estimate the over- and underused families in the medicinal flora. Phylogenetically informed analyses were carried out to identify lineages in which there is an overrepresentation of families in a given category of use, i.e., hot nodes. The ethnobotanicity index, at a specific level, was calculated and also adapted to the family level. Two diversity indices to measure the richness of reported taxa within each family were calculated. A total of 47,630 use reports were analysed. These uses are grouped in 120 botanical families. The ethnobotanicity index for this area is 14.44% and the ethnobotanicity index at the family level is 68.21%. The most-reported families are Lamiaceae and Asteraceae and the most reported troubles are disorders of the digestive and nutritional system. Based on the meta-analytic results, indicating hot nodes of useful plants at the phylogenetic level, specific ethnopharmacological research may be suggested, including a phytochemical approach of particularly interesting taxa.

植物家族在药用民族植物学中的作用：系统发生学的观点

研究表明，并非随机选择药用植物正变得越来越普遍。这项工作的目的是阐明植物科在民族植物学中的作用，以分子系统发育框架描述在几个加泰罗尼亚语地区的家庭与维管植物药用之间的关系。本研究对疾病类别进行了简单的定量分析，并建立了家庭和疾病矩阵。贝叶斯方法用于估计药用菌群中过度使用和未充分使用的科。进行了系统遗传学分析，以鉴定在给定用途类别（即热点）中家族过多的谱系。计算了特定水平的民族植物学指数，并使其适应了家庭水平。计算了两个多样性指数，以衡量每个家庭中报告的分类单元的丰富度。总共分析了47,630个使用报告。这些用途分为120个植物科。该地区的民族植物学指数为14.44％，而家庭水平的民族植物学指数为68.21％。报告最多的家庭是唇形科和菊科，最常报告的问题是消化系统和营养系统的疾病。基于荟萃分析结果，表明在系统发育水平上有用植物的热点，可以建议进行特定的民族药理学研究，包括特别有趣的类群的植物化学方法。该地区的民族植物学指数为14.44％，而家庭水平的民族植物学指数为68.21％。报告最多的家庭是唇形科和菊科，最常报告的问题是消化系统和营养系统的疾病。基于荟萃分析结果，表明在系统发育水平上有用植物的热点，可以建议进行特定的民族药理学研究，包括特别有趣的类群的植物化学方法。该地区的民族植物学指数为14.44％，而家庭水平的民族植物学指数为68.21％。报告最多的家庭是唇形科和菊科，最常报告的问题是消化系统和营养系统的疾病。基于荟萃分析结果，表明在系统发育水平上有用植物的热点，可以建议进行特定的民族药理学研究，包括特别有趣的类群的植物化学方法。
