Pediatric traffic accident herbal duration: ① mild accident: 7 days, ② moderate injury: 10–14 days, ③ severe (rarely in children): 14–21 days, ④ chronic sequelae prevention: as needed. Auto insurance covers reasonable duration. Continue until symptoms fully resolve, not just until pain relieved. Children's bodies recover faster than adults so duration often shorter than adult equivalents. Doctor reassesses at regular intervals.
