How does natural gift work?

Question

I understand it uses the held berry but
1. Is the berry used up at all?
2. What are the types/power of the berries?
3. If a berry, such as oran or sitrus, is consumed will natural gift just fail?

Answer 1

Yes the Berry is used up

Here are the types and powers: http://bulbapedia.bulbagarden.net/wiki/Natural_Gift_(move)#Effect

Yes it will fail if the Berry has already been consumed

These questions have been answered before, look around better before asking
