I have had a lot of luck using the various Bach Flower Essences. Rescue Remedy is a combination of 5 essences. I have used Rescue Remedy for small children going to the dentist, students taking a test (and worried), and one granddaughter on her first plane trip. All these with good success.
In the beginning of my studying the flower essences, they seemed like something that someone made up to make money. But the more I tried them, the more I realized that they actually work.
