Consumable question: Replacement for Charged Crystal Focus

Simple question, kinda gear based (consumable really):

Is there a direct WotLK upgrade to the Charged Crystal Focus health buff consumable?

While a little annoying to farm for, I liked them alot as they acted just like stackable warlock healthstones, and shared the same cooldown so you could pop one of those and a health pot simultaneously in a battle for a big health boost.
