Eucalyptus, particularly its essential oil (eucalyptus oil), has a long history of use for treating respiratory issues, including bronchial congestion. The primary active component, eucalyptol (also known as 1,8-cineole), has demonstrated mucolytic, anti-inflammatory, and bronchodilatory effects in both laboratory and clinical studies. Eucalyptol works by reducing mucus viscosity, making it easier to expel, and also exerts a mild anti-inflammatory action on the airways.

Several clinical studies support its use: randomized controlled trials have shown that orally administered cineole can improve symptoms and lung function in patients with chronic bronchitis, asthma, and COPD by reducing sputum production and easing breathing. Inhalation of eucalyptus oil vapor is commonly used as a home remedy for congestion, and some studies suggest it may help loosen mucus, though direct evidence for inhalation is less robust than for oral use.

Safety considerations include the potential for toxicity, especially in young children, if ingested inappropriately or used in excessive amounts. Topical and inhaled uses are generally safe for adults when used as directed. Overall, eucalyptus oil’s use for bronchial congestion is supported by moderate scientific evidence, as well as a longstanding tradition in herbal and folk medicine.
