How Eucalyptus Oil Helps with Allergies
Eucalyptus oil's 1,8-cineole opens airways, reduces nasal congestion, and has anti-inflammatory effects that calm allergic airway responses.
🔬 What the Research Says
A 2010 randomized trial in Respiratory Medicine found oral cineole (eucalyptus component) significantly improved nasal airflow and reduced congestion compared to placebo.
