The use of an essential oil nasal spray gave rise to significant improvements in patients with allergic sino-nasal symptoms
The use of an essential oil nasal spray led to a 40% reduction in total sino-nasal symptoms according to data presented in an abstract presented at the American Academy of Allergy and Immunology (AAAAI) at San Antonio and published in a supplement to the Journal of Allergy and Clinical Immunology.
Allergic rhinitis gives rise to symptoms which commonly include nasal congestion, nasal itch, rhinorrhoea and sneezing and is estimated to affect 18.1% of the global population, leading to impairment of both sleep and quality of life. Typically, treatment involves the use of antihistamines and or intranasal corticosteroids, although a recent randomised trial demonstrated how aromatherapy oils provided symptomatic relief in patients with perennial allergic rhinitis. Furthermore, the use of a lavender oil inhalation was also found to be of benefit in bronchial asthma.
Given the potential value of essential oils for perennial allergic rhinitis, in the current study presented at AAAAI, the role of an essential oil nasal spray, which contained menthol, eucalyptol, thymol, camphor, birch oil, pine oil, cinnamon and mint, was evaluated over a period of 7 days by patients with seasonal allergic rhinitis. Symptom severity was assessed using the Sino-Nasal Outcome Test (SNOT-22), a patient-reported outcome measure which assesses 22 symptoms, each of which were assessed at baseline and after one week, using a 0 to 5 scale, where 0 = no problem and 5 = ‘problem as bad as can be’
Essential oil nasal spray and SNOT-22 score
A total of 18 subjects (14 women) aged between 16 and 80 were included. The baseline SNOT-22 score was 37.1 and this was significantly reduced to 20.1 (p = 0.003) after one week. In fact, improvements were seen for 20 of the 22 self-reported symptoms, of which statistically significant improvements were documented for 12, with the greatest impact seen for runny nose, cough, postnasal discharge and quality of life features.
The author concluded that the essential oil spray alleviated physical and functional impairment in those with allergic seasonal related diseases.
