Synopsis

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

Cajeput (Melaleuca cajuputi) has a long history of traditional use for respiratory ailments, particularly for easing bronchial congestion. The essential oil is rich in compounds such as cineole (eucalyptol), which imparts a camphoraceous aroma and is believed to have expectorant properties. In traditional medicine systems of Southeast Asia and Australia, cajeput oil has been applied topically or inhaled as a steam to help relieve symptoms of congestion, cough, and cold. Its use for respiratory support is based primarily on anecdotal evidence, traditional practices, and its similarity to eucalyptus oil, another cineole-rich essential oil.

Scientific studies on cajeput itself are limited. Some research on cineole, its main constituent, suggests that it may reduce airway inflammation and facilitate mucus clearance, which could theoretically support its use for bronchial congestion. However, robust clinical trials specifically investigating cajeput oil are lacking. The traditional rating (2) reflects the historical and anecdotal foundation for its use, but the lack of direct, high-quality scientific validation restricts a higher rating. Therefore, while cajeput is commonly used in traditional remedies for bronchial congestion, its efficacy and safety for this purpose have not been rigorously established in modern clinical research.
