The use of Pimpinella species, particularly Pimpinella anisum (anise) and Pimpinella saxifraga (burnet saxifrage), for supporting or treating laryngitis is primarily justified by traditional herbal medicine practices. Historical texts and ethnobotanical records from Europe and Asia note that preparations of Pimpinella roots or seeds have been used as expectorants and for soothing sore throats, coughs, and hoarseness—common symptoms of laryngitis. In particular, Pimpinella saxifraga has a longstanding reputation in European folk medicine for use in "catarrhal conditions of the upper respiratory tract," which includes laryngitis.

While some laboratory studies have identified mild anti-inflammatory and antimicrobial properties in extracts from Pimpinella species, clinical evidence supporting their effectiveness for laryngitis is lacking. The traditional uses are referenced in authoritative herbal compendia such as the German Commission E Monographs and classical herbal texts, but scientific validation through controlled clinical trials is absent. Thus, the support for Pimpinella in laryngitis remains largely anecdotal and rooted in historical practice rather than robust scientific research.
