Objective: To describe the scientific output on medicinal plants published between 2000 and 2019 with at least one author with Peruvian affiliation. Materials and methods: A bibliometric study was carried out by conducting a systematic search in the Scopus database, from which original articles or short communications on medicinal plants that had at least one author with Peruvian institutional affiliation were selected. The characteristics of the publications, institutions, countries and authors who participated in this research are described. The ratio of international collaboration, the transience index, and the institutional and co-authorship collaboration networks were calculated. Results: A total of 200 original articles published in 83 journals were included. The quantity of articles showed an increasing, though irregular trend during the studied period. The most productive institution was the Universidad Nacional Mayor de San Marcos, and the journal in which most of the articles were published was the Journal of Ethnopharmacology. Authorship and institutional collaboration networks showed the influence of international collaboration in these publications (53.0%). Conclusions: Peruvian scientific output on medicinal plants shows an increasing trend, observed mainly in academic university settings. The articles are published on high-impact journals, due in part to the high level of international cooperation.
