Does anyone know anything about natural pain relief and anti-inflammatories for birds? I have read a little about cayenne pepper, but how much should you give a young pigeon?

I see a lot about using Tobacoo stems as nesting material for its natural insect repellent activities. Not many folks, at least up north, have tobacco fields around them (though I do grow a variegated version in my garden). Anyway, pine needles also have some insect repellent properties...

I just wanted to know what are other alternatives i can use for bath water for pigeons instead of the one i can buy at the store??? :)
