Medicinal plants are used by local populations to treat numerous diseases, and many species are used as raw materials for the manufacture of medicines sold by the pharmaceutical industry. However, the intensive collection of these resources poses great challenges related to their conservation. Through a systematic review, we gathered information on the versatility of medicinal trees from seasonal dry forests (Caatinga) in order to create a conservation priority index (CPI) for these species. We found that demand by the pharmaceutical industry is a factor that must be taken into account when establishing conservation priorities for medicinal plants. We found that endemism was not a determining factor in the identification of priority species for conservation. The effects of extractivism on the demographics of Handroanthus impetiginosus (Mart. Ex DC.) Mattos, Anacardium occidentale L., and Copaifera langsdorffii Desf. populations require urgent assessment, because these species are in high demand by local communities and the pharmaceutical industry. Ecological studies may reveal strategies that should be incorporated into their management plans, which can include an increase in time between collection intervals, the production of plant nurseries, the implementation of reforestation programs, and cryopreservation, in addition to the involvement of the local community in monitoring programs. Other indicators such as the importance of species for the maintenance of ecosystem services, productivity chains, and the elaboration of public policies can be included as conservation strategies for these species.

药用植物被当地居民用来治疗多种疾病，许多物种被用作制造制药业出售的药物的原料。但是，对这些资源的密集收集带来了与其保存相关的巨大挑战。通过系统的审查，我们收集了来自季节性干旱森林（Caatinga）的药用树木的多功能性信息，以便为这些树种建立保护优先级指数（CPI）。我们发现，制药行业的需求是确定药用植物保护重点时必须考虑的因素。我们发现地方性不是确定优先保护物种的决定因素。提取主义对人口统计的影响Handroanthus impetiginosus（Mart。Ex DC。）Mattos，Anacardium occidentale L.和Copaifera langsdorffiiDesf。种群需要紧急评估，因为当地社区和制药行业对这些物种的需求很高。生态学研究可能会揭示应纳入其管理计划的策略，除了当地社区的参与外，其中可能包括增加收集间隔之间的时间，种植苗圃，实施重新造林计划和低温保存。监控程序。其他指标，例如物种对于维持生态系统服务的重要性，生产力链以及制定公共政策，也可以作为这些物种的保护策略。
