Synopsis

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

Anise (Pimpinella anisum) has a long history of traditional use for relieving symptoms associated with dry coughs. In various traditional medicine systems, including those of the Middle East, Mediterranean, and South Asia, anise seeds are prepared as teas, infusions, or syrups to soothe the throat and alleviate cough. The main constituents of anise, such as anethole, are believed to possess mild expectorant, antispasmodic, and soothing effects on the respiratory tract. These traditional uses are documented in herbal medicine literature and ethnobotanical studies.

However, scientific validation for its efficacy in treating dry cough specifically is limited. While some laboratory and animal studies suggest that anise extracts may have antitussive (cough-suppressing) and antimicrobial properties, robust clinical trials in humans are lacking. Most of the evidence remains anecdotal or based on historical usage. Some cough syrups and herbal teas commercially available contain anise or its essential oil as an ingredient, likely reflecting its traditional reputation rather than strong clinical evidence. Overall, the use of anise for dry cough is primarily justified by traditional practices rather than scientific validation, and the quality of evidence is modest (rated 2 out of 5).
