Ravintsara (Cinnamomum camphora ct. 1,8-cineole) essential oil is commonly used in traditional aromatherapy for the relief of cold symptoms, especially as a decongestant. This use is based primarily on historical and anecdotal practices, especially in Madagascar and among practitioners of French aromatherapy. Ravintsara contains a high proportion of 1,8-cineole (eucalyptol), a compound also found in eucalyptus oil, which is known for its expectorant and decongestant properties. However, the bulk of evidence supporting Ravintsara’s use is extrapolated from studies on 1,8-cineole, not on Ravintsara oil itself.

There are a few laboratory and animal studies indicating that 1,8-cineole can reduce airway inflammation and improve mucociliary clearance, supporting the plausibility of decongestant effects. However, robust clinical trials specifically on Ravintsara oil for cold symptoms are lacking. Most recommendations are thus based on traditional use rather than direct scientific validation. Users typically employ the oil via inhalation or topical application (when diluted), but safety and efficacy data are limited.

In summary, while there is traditional support and some indirect scientific rationale (via 1,8-cineole), there is limited direct clinical evidence for Ravintsara as a decongestant for colds. Its use remains popular in alternative and complementary medicine circles, but more research is needed to substantiate its efficacy.
