Breastfeeding
Use CautionSedative herbs can cause infant drowsiness via breast milk — generally used cautiously and briefly, watching the baby for excess sleepiness or poor feeding.
Children
Use CautionSedative herbs are dose-sensitive in children, whose smaller body size makes effects less predictable — start low and use short-term under guidance.
