However, additional medicinal uses preserved by the Chinantec people of Oaxaca, Mexico, remain largely undocumented and are at risk of disappearing, as this knowledge is now held by only a few individuals. This study gathered information on the therapeutic applications of T. ascendens in the Chinantla region through semi-structured interviews with key collaborators. Information was collected regarding the socio-demographic profiles of the collaborators, as well as the conditions treated, plant parts used, preparation modes, and doses. The species is used to alleviate headaches, toothaches, stomach pains, menstrual pains, body aches, kidney diseases, and inflammation, as well as to treat cultural diseases known as \u201cmal de orin\u201d and \u201csangre sucia\u201d. Infusions made from mature or developing leaves, along with topical application of crushed leaves, are the main forms of administration. The traditional knowledge documented here underscores the importance of further research to identify the bioactive compounds in T. ascendens and to evaluate their potential inflammatory and analgesic effect. Such studies could lead to the discovery of new pharmacologically active molecules while preserving valuable traditional knowledge.<\/jats:p>","DOI":"10.3390\/plants15060873","type":"journal-article","created":{"date-parts":[[2026,3,12]],"date-time":"2026-03-12T14:46:31Z","timestamp":1773326791000},"page":"873","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ethnomedicinal Knowledge of Trichocentrum ascendens (Orchidaceae) in an Indigenous Region of Oaxaca, Mexico"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-2552-0331","authenticated-orcid":false,"given":"Mayra Ariadna","family":"Garc\u00eda-Pati\u00f1o","sequence":"first","affiliation":[{"name":"Laboratorio de Extracci\u00f3n y An\u00e1lisis de Productos Naturales, Centro Interdisciplinario de Investigaci\u00f3n para el Desarrollo Integral Regional Unidad Oaxaca, Instituto Polit\u00e9cnico Nacional, Hornos 1003, Santa Cruz Xoxocotl\u00e1n 71233, Oaxaca, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9870-971X","authenticated-orcid":false,"given":"Luicita","family":"Lagunez-Rivera","sequence":"additional","affiliation":[{"name":"Laboratorio de Extracci\u00f3n y An\u00e1lisis de Productos Naturales, Centro Interdisciplinario de Investigaci\u00f3n para el Desarrollo Integral Regional Unidad Oaxaca, Instituto Polit\u00e9cnico Nacional, Hornos 1003, Santa Cruz Xoxocotl\u00e1n 71233, Oaxaca, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela Soledad","family":"Barrag\u00e1n-Z\u00e1rate","sequence":"additional","affiliation":[{"name":"Laboratorio de Extracci\u00f3n y An\u00e1lisis de Productos Naturales, Centro Interdisciplinario de Investigaci\u00f3n para el Desarrollo Integral Regional Unidad Oaxaca, Instituto Polit\u00e9cnico Nacional, Hornos 1003, Santa Cruz Xoxocotl\u00e1n 71233, Oaxaca, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1913-5418","authenticated-orcid":false,"given":"Jes\u00fas Alejandro","family":"R\u00edos-Solis","sequence":"additional","affiliation":[{"name":"Laboratorio de Extracci\u00f3n y An\u00e1lisis de Productos Naturales, Centro Interdisciplinario de Investigaci\u00f3n para el Desarrollo Integral Regional Unidad Oaxaca, Instituto Polit\u00e9cnico Nacional, Hornos 1003, Santa Cruz Xoxocotl\u00e1n 71233, Oaxaca, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0355-5496","authenticated-orcid":false,"given":"Rodolfo","family":"Solano","sequence":"additional","affiliation":[{"name":"Laboratorio de Extracci\u00f3n y An\u00e1lisis de Productos Naturales, Centro Interdisciplinario de Investigaci\u00f3n para el Desarrollo Integral Regional Unidad Oaxaca, Instituto Polit\u00e9cnico Nacional, Hornos 1003, Santa Cruz Xoxocotl\u00e1n 71233, Oaxaca, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,12]]},"reference":[{"key":"ref_1","first-page":"559","article-title":"Checklist of the native vascular plants of Mexico","volume":"87","year":"2016","journal-title":"Rev.
