Rating (out of 5): 3

Cineole (also known as eucalyptol) is a monoterpenoid compound found predominantly in eucalyptus oil. Its use for treating or supporting dry cough is supported by moderate scientific evidence. Cineole exerts its effects through several mechanisms, including mucolytic (mucus-thinning), bronchodilatory, and anti-inflammatory actions. Several clinical trials and reviews have shown that cineole can reduce the frequency and severity of cough in patients with respiratory conditions, such as bronchitis and asthma, which often include symptoms of dry cough.

For example, randomized controlled studies have demonstrated that oral cineole (commonly at doses of 200 mg three times daily) can significantly decrease cough frequency and improve pulmonary function in patients with acute and chronic bronchitis. Its efficacy appears to stem from its ability to reduce airway inflammation and increase the secretion of less viscous mucus, thus soothing irritation in the respiratory tract that can provoke dry cough. Additionally, cineole has been shown to exert antimicrobial effects, which may be beneficial if cough is associated with mild infections.

While the evidence base is not as robust as for some conventional antitussives, and most studies focus on broader respiratory conditions rather than isolated dry cough, reviews in reputable journals and meta-analyses support the beneficial effects of cineole in respiratory tract diseases with cough as a prominent symptom. Therefore, its use is considered scientifically justified, with a moderate evidence rating.
