Eucalyptus, particularly its essential oil (Eucalyptus globulus), has been used traditionally for respiratory complaints, including sinus-related headaches. Scientifically, eucalyptus oil contains eucalyptol (1,8-cineole), which exhibits anti-inflammatory, analgesic, and decongestant properties. Several small clinical studies and laboratory investigations suggest that inhaling eucalyptus oil vapor or using it in topical preparations can help relieve sinus congestion, which is often a major contributor to sinus headaches. For example, a randomized controlled trial published in "Laryngoscope" (2009) found that 1,8-cineole significantly improved symptoms of acute rhinosinusitis compared to placebo, including headache relief, likely due to its mucolytic and anti-inflammatory effects.

However, while there is some clinical evidence supporting the use of eucalyptus for sinus congestion (and thus, indirectly, for sinus headaches), the evidence base is relatively limited, with most studies small in size or focused on broader respiratory symptoms. There is a lack of large-scale, high-quality trials specifically targeting sinus headache as an isolated outcome. Traditional use and anecdotal reports also support its use for headache and congestion relief, especially in forms such as steam inhalation or balms.

In summary, eucalyptus is scientifically plausible for easing sinus headache symptoms due to its decongestant and anti-inflammatory effects, but the strength of evidence is moderate at best (rated 2/5), and more targeted research is needed for definitive recommendations.
