Source of validity: Traditional
Rating (out of 5): 2

Berries, in general, have a long-standing history in traditional medicine systems across various cultures for the treatment of cough and related respiratory ailments. Specific berries such as elderberry (Sambucus nigra), black currant, and mulberry have been particularly prominent in folk remedies. For example, elderberry syrup has been used in European herbal traditions to alleviate symptoms of upper respiratory tract infections, including cough. The rationale for their use often centers on their purported anti-inflammatory, antioxidant, and antiviral properties—attributes ascribed to the high content of anthocyanins, flavonoids, and vitamin C present in many berries.

However, direct scientific evidence supporting the efficacy of generic "berry" supplementation for cough relief is limited. Most modern scientific studies focus on specific berries rather than berries as a group, and while there is some emerging research on elderberry, there is insufficient robust clinical data to conclusively validate its effectiveness specifically for cough. The use of "berry" for cough is thus primarily justified by traditional practices rather than modern scientific validation. Consumers should be aware that while there may be a historical basis and some plausible mechanisms, the evidence base remains moderate to weak and largely anecdotal for most berry types.
