Type 2 diabetes mellitus is a chronic disease with a high prevalence in rural and indigenous communities of Guatemala, in which the use of medicinal plants for its treatment has been reported. In order to know which plants are used by the population for this condition, an ethnopharmacological study was carried out with 36 individuals from the Tz'utujil population of Santiago Atitlán, Sololá, through an anthropological and pharmacological-toxicological analysis of semistructured interviews and open questionnaires. Nineteen plants were identified, and the disease consensus index (DCI) and the value in use (UV) were calculated to assess the knowledge and relative importance of each species; both values help to understand the cultural relevance, that is, the importance of medicinal species for the population. The five plants with the higher cultural relevance were Neurolaena lobata R.Br. ex Cass. (DCI = 0.4074, UV = 0.0084), Artemisia absinthium L. (DCI = 0.1481, UV = 0.0027), Psidium guajava L. (DCI = 0.1111, UV = 0.0023), Tanacetum parthenium (L.) Sch.Bip. (DCI = 0.0741, UV = 0.0015) and Coffea arabica L. (DCI = 0.0741, UV = 0.0015). It was determined that N. lobata and P. guajava have a high potential to treat diabetes, C. arabica and T. parthenium can cause adverse effects and interactions with certain medications, and A. absinthium can be dangerous if consumed. However, further studies of the isolated secondary metabolites responsible for antidiabetic activity are required to establish safe doses, adverse effects, interactions and toxicology.
