What are some safe herbs for anxiety that I can administer to my 10-year-old daughter?

Name: Neeta Date of Birth: 14 August 1987 Place of Birth: Mumbai Time: 03:45 PM. Hello, I am a mother to a 10-year-old girl who has been displaying symptoms of anxiety, nighttime disturbances, nail biting, and persistent stomach upset. I don't wish to medicate her unless absolutely necessary. I'm hoping for gentle, natural herbs that are children-safe and will make her feel more relaxed. I've heard about lemon balm and chamomile, but I'm not sure what to use and at what dosage, or if they are safe. Are there pediatric-safe herbal supplements that would minimize anxiety in children without side effects?
