Effects of chamomile oil inhalation on sleep quality in young adults with insomnia: A randomized controlled trial

Insomnia is characterized by difficulty falling asleep, staying sleep, or both. Aromatherapy is a commonly used complementary and alternative medicine practice by persons with insomnia. Previous studies have shown that use of chamomile oil during massage therapy improves the quality of sleep (QoS). However, to our knowledge, no randomized controlled trials have examined the effects of chamomile oil inhalation on the treatment of insomnia. The present study evaluated the effect of chamomile oil inhalation on QoS and insomnia severity in persons with insomnia.
