Rheumatoid arthritis (RA) and osteoarthritis (OA) are social impact disorders that lead to intense pain, deformities, and inability to perform daily and work-related activities. In Brazil, despite the National Policies for Integrative and Complementary Practices (PNPIC) and Medicinal Plants and Phytotherapies (PNPMF) that have expanded access to Phytotherapy, the incorrect dissemination of the use of medicinal plants remains common, often without any scientific evidence of efficacy. The aim of this study was to select some plants popularly recommended on the internet for treating RA and OA and to gather data on their efficacy and safety. These plants include Harpagophytum procumbens, Hypericum perforatum, Miconia albicans, Uncaria tomentosa, and Varronia curassavica. A literature review covering in vitro, preclinical, and clinical trials revealed promising results regarding the action of these plants on RA and OA. Most studies emphasize the anti-inflammatory, anti-arthritic, and analgesic effects of these species. However, as the mechanisms are not yet fully understood, further studies, particularly clinical trials, are necessary to reach a more definitive conclusion. This literature review can contribute to and alert healthcare professionals and patients seeking these products for the treatment of rheumatic diseases.
