The higher prevalence found by Araújo et al.8 could be attributed to the fact that it measured the use of medicinal plants in individuals who were followed up in primary health care, as opposed to the current study, which estimated the use of plant medicinal products through a population-based study.
We discovered that 40.2% of the study population used medicinal plants, comparable to the 42.7% found by Gonçalves et al.7 in a small northeastern Brazilian city. However, Araujo et al.8 discovered that 79% of respondents treated at a primary health unit in northeastern Brazil used medicinal plants, which is higher than the percentage found in our study. The higher prevalence found by Araújo et al.8 could be attributed to the fact that it measured the use of medicinal plants in individuals who were followed up in primary health care, as opposed to the current study, which estimated the use of plant medicinal products through a population-based study. Conversely, medicinal plants were utilized by only 21% of patients receiving treatment at primary health centers in southern Brazil9. As a result, we identified that the prevalence of the use of medicinal plants varies greatly across Brazil. The northernmost municipalities have the highest use and the southernmost municipalities having the lowest use8, 9.
