Eucalyptus
Eucalyptus globulus
Historical / Folk Use
Eucalyptus has long been used in Australian and global herbal traditions for its invigorating aroma and refreshing character. Traditionally, leaves were crushed or infused into oils and poultices to accompany inhalation rituals, aromatic steam practices, baths, and topical preparations.
In aromatic blends, it was valued for promoting a sense of open breathing and environmental freshness. Its crisp, cooling character helps support a sense of clarity, and ease of breathing.

Study 1:
Another clinical trial in adults with rheumatoid arthritis reported that eucalyptus oil inhalation was associated with reduced self‑reported pain severity and improved quality of life after one month of regular inhalation alongside standard care.
Study 2:
A double‑blind, placebo‑controlled study in healthy volunteers evaluated a topical preparation containing eucalyptus oil, peppermint, and ethanol applied to the forehead and temples. The preparation was associated with changes in cognitive measures and muscle relaxation indicators.
Study 3:
In a controlled study of adult volunteers, inhalation of eucalyptus essential oil was associated with changes in brain electrical activity and decreased systolic blood pressure that reflect relaxation‑related physiological responses during olfactory stimulation.
Study 4:
In a separate placebo‑controlled randomized trial in adults with stable COPD, cineole therapy was associated with reduced frequency, severity, and duration of exacerbations, along with improvements in lung function and dyspnea measures — outcomes that relate to airway inflammation and mucus membrane responses.
Study 5:
Reviews of clinical evidence on essential oil components note that cineole is associated with mucolytic, expectorant, and symptomatic improvements in acute airway conditions such as acute bronchitis and rhinosinusitis when studied in controlled clinical settings.
Study 6:
Clinical research involving cineole, the dominant constituent of eucalyptus essential oil, has shown associations with reduced cough frequency and improvement in bronchitis symptoms in adults in a double‑blind, placebo‑controlled trial.
Study 7:
Laboratory research consistently demonstrates that eucalyptus essential oil is associated with antimicrobial activity in vitro against a range of bacterial and fungal organisms when tested under controlled laboratory conditions.
