Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Potentilla species (commonly known as cinquefoil) have a long history of use in traditional medicine, particularly in Europe and Asia, for the treatment of external ulcerations, wounds, and other skin conditions. The primary basis for this use comes from folk medicine practices, where Potentilla preparations (such as poultices, infusions, or ointments) were applied to ulcers, sores, and inflamed skin to promote healing and reduce inflammation. Historical herbal texts, including those by Nicholas Culpeper and entries in various ethnobotanical surveys, describe Potentilla as an astringent due to its high tannin content. This astringency was believed to help dry out wounds and ulcers, thereby aiding in the healing process and preventing infection. However, while the presence of tannins and other polyphenols in Potentilla species is well documented, there is a lack of robust modern clinical trials or scientific studies directly evaluating the efficacy of Potentilla for external ulcerations. Most available data are limited to in vitro studies or traditional use records, with few animal studies and virtually no controlled human trials. Therefore, the evidence supporting its use is primarily traditional and rated as moderate (2/5), reflecting both its historical prominence and the absence of high-quality scientific validation.
