I just got a Jirachii from Pokemon Channel, and it's holding a "Salac Berry". The Jirachi alone is royally cool, but a funky berry?! Woo! Checking up on it over at Pokemon Forever, the berry (along with several others) 'when in a pinch' raises speed. I was just wondering, does that mean that a pokemon eats it when on low health (BTW, how low health?) and its speed rises?

I'm confused, because with other items it has similar synopsis, but I don't know if the berry gets eaten or not.

Thanks.
