Short answer
Lavender, known scientifically as Lavandula angustifolia, is a well-known botanical traditionally used to support relaxation, sleep onset, and emotional balance.
Research suggests lavender may help reduce presleep anxiety, promote calmness, and support sleep quality by influencing nervous system activity and stress-related pathways.
Rather than acting as a sedative, lavender helps create the relaxed mental state needed for natural sleep.
Difficulty falling asleep is often linked to stress, emotional tension, and nervous system overactivity. Lavender is one of the most widely recognized botanicals used to support relaxation before bedtime.
What is Lavender?
Lavender refers primarily to Lavandula angustifolia. In supplements, lavender is typically used as a standardized extract providing linalool, linalyl acetate, and polyphenolic compounds.

Sleep onset support
Lavender is most strongly associated with helping reduce the time it takes to fall asleep by supporting the mental and emotional conditions that allow sleep to occur naturally.
