I have a book on the Bach's Flower Essences. It seems interesting, similar to homeopathy. The only way I've been able to find the single flower essence (this was years ago and don't remember what internet site I found individuals) was in an alcohol base....Not safe for birds!! Don't give your birds anything with alcohol in it. But Amazon.com carries Bach's Rescue Remedy for Pets...which is in a glycerin base and safe for birds. I put it in their water. Not sure if it calms them down.....I have 2 caiques and one has really high energy.
