When ingested in appropriate amounts, lavender can reduce nervous tension, promote restful sleep, and even help ease anxious thoughts. It influences the parasympathetic nervous system, the part of our body responsible for relaxation and digestion. That’s why you’ll often hear of people adding a few drops of lavender oil to their diffuser before bed, but in doTERRA Serenity Softgels, this benefit comes in a ready-to-swallow capsule form.
