Research from Korea’s Chung-Ang University has found that inhaling aromatherapy infusions comprising a combination of sandalwood, frankincense and ravensara for five minutes twice daily significantly reduces symptoms of allergies after seven days. The researchers tested 54 men and women, half of which were tested using a placebo of almond oil.
Total nasal symptom score (TNSS) and rhino-conjunctivitis quality of life questionnaire (RQLQ) results were both significantly lower in the aromatherapy group. TNSS scores decreased by more than half and RQLQ scores decreased by more than 60 percent. Scores for fatigue and sleep quality also improved in the aromatherapy group.
“These findings indicate that inhalation of certain aromatherapy oils help relieve perennial allergic rhinitis symptoms, improve rhinitis-specific quality of life and reduce fatigue in patients with perennial allergic rhinitis,” Chung-Ang University’s Seo Yeon Choi and Kyungsook Park explain in their paper
