Rating (out of 5): 2

Raspberry (Rubus idaeus), specifically its leaves, has a history of use in traditional herbal medicine for soothing coughs and sore throats. Folk remedies and traditional European herbalism have employed raspberry leaf tea as a mild astringent and demulcent, intended to reduce throat irritation and help alleviate cough symptoms. The tannins and flavonoids present in raspberry leaves are believed to contribute to these effects by exerting mild anti-inflammatory and soothing actions on mucous membranes.

However, the scientific evidence supporting raspberry's efficacy in treating cough is limited. There are few, if any, clinical studies that specifically investigate raspberry (fruit or leaf) for cough relief in humans. Most available research focuses on raspberry's antioxidant properties or its use in women's reproductive health rather than its effects on respiratory symptoms. Observed benefits in traditional settings may be due to general soothing effects of warm herbal teas and not specific to raspberry itself.

In summary, the use of raspberry for supporting or treating cough is primarily rooted in traditional use, particularly with raspberry leaves in herbal teas. While there are plausible mechanisms (such as astringency and mucosal soothing), robust scientific validation is lacking. Thus, raspberry may be used as a gentle, traditional home remedy for cough, but should not be relied upon as a primary or evidence-based treatment for respiratory conditions.
