Rating (out of 5): 2

Ferns, particularly species such as Dryopteris and Adiantum, have a long history of use in traditional medicine systems across various cultures for the management of bleeding, especially external bleeding. In folk medicine, fern fronds have been applied directly to wounds as a poultice or dressing with the belief that they help to staunch bleeding and promote healing. Ethnobotanical records from regions such as Europe, Asia, and the Americas document the use of fern leaves for their purported astringent and styptic properties, which are thought to constrict tissues and blood vessels, thereby reducing blood flow from wounds.

However, there is limited scientific research to substantiate these traditional practices. The evidence base primarily consists of anecdotal reports and ethnomedicinal documentation rather than rigorously controlled studies. Some phytochemical analyses have revealed the presence of tannins and other compounds in certain fern species that possess astringent properties, which may theoretically contribute to hemostatic effects. Nonetheless, the lack of clinical trials or robust pharmacological studies means that the efficacy and safety of fern preparations for bleeding control remain largely unproven by modern standards.

In summary, the use of ferns for external bleeding is rooted in traditional medicine, with a moderate level of ethnobotanical evidence but little to no scientific validation. Therefore, while tradition supports their use, scientific endorsement is lacking, and caution is advised if considering fern-based remedies for bleeding.
