Rating (out of 5): 2

Palm-Leaf Raspberry (Rubus palmatus or related Rubus species) has a history of use in traditional medicine, particularly in parts of East Asia. Traditional healers have used the leaves and fruits to treat a variety of ailments, including sore throat. The rationale for its use often stems from the plant's astringent properties—tannins in the leaves can help soothe mucous membranes and reduce throat inflammation. Folk remedies may also employ infusions or gargles made from the leaves to alleviate throat discomfort.

However, scientific evidence supporting the use of Palm-Leaf Raspberry for sore throat is limited. While general studies on Rubus species suggest antimicrobial and anti-inflammatory properties, these are neither specific to Palm-Leaf Raspberry nor its application for sore throat. There are no well-controlled clinical trials or robust pharmacological studies directly validating its efficacy for this condition. Most available data are derived from broader ethnobotanical surveys or in vitro studies on related Rubus species.

In summary, the use of Palm-Leaf Raspberry for sore throat is justified by a traditional basis, but scientific validation is weak. Its role in sore throat relief relies mainly on historical use and anecdotal evidence rather than rigorous scientific research.
