Eucalyptus Branches Causing Breathing Difficulty: Allergic Reaction?

A reader experienced severe breathing difficulty when sniffing dried eucalyptus branches in a vase with artificial plants. The vase is in a den next to their bedroom. They removed the branches and plan to incinerate them.

Possible Causes

• Allergic reaction to eucalyptus pollen or preservatives on the branches.
• Aroma may concentrate in poorly ventilated rooms or if stems sit in stagnant water.

Recommendation

Discard the vase and contents immediately. Consult a doctor or allergist—the expert has no medical training and cannot diagnose. The reaction, while uncommon, is plausible.
