The aim of this study was to systematically review the use of medicinal plants for the treatment of varicose ulcers. The databases used in the search were: Medline/Pubmed, Scopus, Cinhal, Lilacs and Web of Science. The selection process was divided into two phases: the reading of titles and abstracts and the full reading of selected articles. The item description was compared with the checklist of the Consolidated Standards of Reporting Trials. The initial search produced 3505 articles and seven were selected for inclusion in the systematic review. Of the included studies, 7 (100%) evaluated the reduction of the ulcer area, 4 (57·14%) evaluated reepithelisation, 2 (28·57%) evaluated bacterial flora and 1 (14·28%) evaluated the oxygen pressure and percutaneous carbon dioxide. The level of evidence rating indicated that five studies (71·42%) were rated at level 2 and two (28·57%) were rated at level 3. The quality assessment was performed using the Jadad scale, which is prevalent in the literature. The quality score of the Jadad questionnaire ranges from 0 to 5; here, the studies analysed had an average of 2·5. A meta-analysis was performed on two studies that analysed the effects of Mimosa tenuiflora hydrogel in the treatment of venous ulcer and included 42 patients with a mean age of 60·5 years and a mean duration of treatment of 10·5 weeks. Heterogeneity was assessed using I2 ; we obtained a high value of 84%. We concluded that, despite the efficacy of the incorporation of Ageratina pichinchensis into the gel, the hydrogel that incorporated M. tenuiflora appeared to be a promising candidate for the management of venous ulcers.
