The primary mode of action involved an immunomodulatory role towards the Th1 response in the up-regulation of IFN-\u03b3 and IL-12 and the suppression of IL-10 gene expression profiling against cutaneous leishmaniasis caused by <jats:italic>Leishmania major<\/jats:italic>.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Conclusion.<\/jats:bold> This finding suggests that the extract possesses multiple combinatory effects of diverse bioactive phytochemical compositions that exert its mechanisms of action through agonistic-synergistic interactions. The topical extract formulation could be a suitable and unique candidate for future investigation and pharmacological development. Further studies are crucial to evaluate the therapeutic potentials of the extract alone and in combination with conventional drugs using clinical settings.<\/jats:p>","DOI":"10.1099\/jmm.0.001333","type":"journal-article","created":{"date-parts":[[2021,6,11]],"date-time":"2021-06-11T16:16:25Z","timestamp":1623428185000},"source":"Crossref","is-referenced-by-count":8,"title":["Leishmanicidal
