Eucalyptus oil opens up the lungs and sinuses, thereby improving circulation and reducing symptoms of allergies. Studies have shown that it produces a cold sensation in the nose that helps to improve airflow.
Eucalyptus contains citronellal, which has analgesic and anti-inflammatory effects; it also works as an expectorant, helping to cleanse the body of toxins and harmful microorganisms that are acting as allergens.
Remedy: To treat respiratory issues associated with allergies, diffuse five drops of eucalyptus at home or apply it topically to the chest and temples.
To clear the nasal passages and relieve congestion, pour a cup of boiling water into a bowl and add 1–2 drops of eucalyptus essential oil. Then place a towel over your head and inhale deeply for 5–10 minutes.
