Treatment of snorers with a volatile oil: a randomized, double-blind placebo-controlled trial

Snoring is a significant problem both for the patient and for the bed partner. Seventy-two male and female heavy snorers and their bed partners participated in a double-blinded, placebo-controlled study on the effects of a volatile oil administered by gargling. The patients were diagnosed as heavy snorers after they underwent overnight polysomnography showing that their apnea indexes were below 5, thus sleep apnea patients were not included in the study. The participants and their partners filled out evaluations concerning snoring intensity, mouth dryness, nasal stuffiness and the Epworth Sleepiness Scale prior to and after using the volatile oil or placebo for 14 consecutive nights. There were no statistically significant decreases in snoring as graded by the bed partner or in mouth dryness, nasal stuffiness, or the Epworth Sleepiness Scale scores graded by the patients who were randomized to use the volatile oil. The results of this study indicate that this volatile oil is not an effective treatment in patients presenting with symptoms of snoring.
