I know that cure poison is fron vine spell category, but what level spell it is ?
I'm very angry about wondering around serpent temple and get poisoned´, and no way to cure.
Please send info to me !

Cure Poison is a... let me look it up... 4th level Vine spell. Time to get a ranger or cleric in your group.
The other two solutions are to pay the local temple waaaaay too much gold for a cure, or to suck down those yellow cure poison potions.

Um, the answer is in the manual you got with the game. Don't you have one?
