Health properties
Expectorant and decongestant: eucalyptus oil (rich in 1,8‑cineole/eucalyptol) helps loosen mucus and relieve nasal and chest congestion.
Antimicrobial and antiseptic: topical and vapor uses show antibacterial, antiviral, and antifungal activity in vitro; used in minor wound cleansing.
Anti‑inflammatory and analgesic: inhalation or topical application can reduce airway inflammation and relieve muscle aches when diluted.
Antipyretic/supportive for colds: traditional use for fever and respiratory infections; evidence supports symptomatic relief rather than cure.
