Rating (out of 5): 2
Maidenhair Fern (Adiantum capillus-veneris) has a long history of use in traditional medicine systems, particularly in European, Middle Eastern, and South Asian herbal practices, for respiratory ailments including wheezing, cough, and bronchitis. The fern’s fronds have been prepared as infusions, syrups, or decoctions, often referred to as "capillaire" syrup in historical texts, and administered to soothe the respiratory tract. Traditional Persian and Unani medicine, as well as some Western herbal traditions, cite its use as an expectorant and demulcent believed to help clear the airways and reduce irritation, thereby potentially alleviating symptoms such as wheezing.
However, scientific validation for these uses is limited. While some in vitro studies have identified mild anti-inflammatory and antioxidant properties in Maidenhair Fern extracts, there is a lack of robust clinical trials demonstrating efficacy for wheezing or other respiratory symptoms. The evidence supporting its use is therefore based primarily on historical and ethnobotanical reports rather than modern pharmacological research. As such, the use of Maidenhair Fern for wheezing remains largely traditional, and more rigorous scientific research would be required to confirm its safety and effectiveness for this indication.
