Rosemary essential oil is rich in 1,8-cineole (eucalyptol), a natural compound known for its:
Anti-inflammatory properties
Antimicrobial effects
Mucolytic activity (helps break down mucus)
This makes it a gentle but effective ally against sinus congestion, blocked nasal passages, and even sinus headaches.
📊A 2004 study published in Respiratory Medicine found that 1,8-cineole improved symptoms in patients with chronic sinusitis and reduced the need for antibiotics by 44%.
