Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Eucalyptus, particularly its essential oil (eucalyptus oil), has a well-established history of use in the management of cough, including spastic (irritative or dry) cough. The primary active compound, 1,8-cineole (also known as eucalyptol), is responsible for much of its pharmacological activity. Scientific studies have shown that 1,8-cineole has mucolytic (mucus-thinning), bronchodilatory, and anti-inflammatory effects, which can help ease coughing and improve airway function. Several randomized controlled trials and meta-analyses have found that oral and inhaled preparations containing 1,8-cineole can reduce the frequency and severity of coughing in conditions such as bronchitis and upper respiratory tract infections. Additionally, both the European Medicines Agency and the German Commission E recognize eucalyptus leaf and oil as traditional herbal medicines for cough and cold symptoms, supporting their use by both tradition and clinical evidence.

However, while the evidence for efficacy is moderate and supportive, it is not as strong as for some conventional antitussives; most studies report modest benefit rather than dramatic effects. Furthermore, eucalyptus oil must be used with caution, especially in children, due to potential toxicity if ingested in large amounts. Overall, the use of eucalyptus for spastic cough is justified by both traditional practice and scientific evidence, with the scientific rating reflecting positive, though not overwhelming, clinical support.
