Abstract: Essential oils (EOs) are a volatile mixture of bioactive compounds extracted from aromatic
plants. The composition of EOs varies, which majorly depends on the extraction methods and
plant parts. Aromatherapy using EOs has been reported for its several beneficial effects in humans.
Aromatherapy is considered a complementary and/ or adjuvant therapeutic approach for treating
several illnesses, especially to improve mental health and well-being. The incidence of sleep disorders,
specifically insomnia, is nowadays increased, possibly due to urbanization and lifestyle. The
studies showed that EOs-based treatments using lavender EO, bergamot EO, cinnamon EO, and
rosemary EO (alone or in combinations) could improve sleep quality, duration, and deprivation in
healthy subjects and patients, those who suffer from sleep-related issues. The current manuscript
details the outcomes of EO-based treatments on the sleep quality of humans and the possible mechanisms
associated with the health-promoting properties of EOs. Also, the toxicity and adverse effects
of EOs have been discussed. The study indicated that EOs are potent adjuvant therapeutic candidates
to manage mood-associated complications in humans. Moreover, the aromatherapeutic field
requires detailed studies on toxicity and dose determination, which could provide safe and effective
therapeutic results.
