Short answer: Passionflower helps support relaxation of the nervous system and may ease nerve-related tension, while California Poppy is valued for its gentle calming and muscle-relaxing properties.
Why these two calming botanicals are paired together
Passionflower's role centers on nervous-system relaxation, while California Poppy's role centers more specifically on muscle relaxation and restful recovery — two complementary, not overlapping, contributions.
Why both ingredients carry the same disclosed caution
Both are specifically flagged as "may cause drowsiness" — a shared effect worth taking seriously together, especially before driving.
⚠️ Worth knowing: do not drive or operate machinery until you know how NervEase affects you, given this combined calming effect.
