Abstract

We reviewed 20 randomized controlled trials concerning the intervention methods and effects of lavender essential oil on adults' sleep quality. Fourteen showed positive intervention effects. A mixture of subjective and objective indicators was used. Lavender essential oil was associated with improved sleep quality before insomnia or other sleep disorders occurred.
