How to get Antitoxin recipe? I already ask all of them(not at all) or i need to upgrade intelect for getting the recipe?
Antitoxin is one of three recipes (Poison Extract, Poison Bomb and Antitoxin) you learn from the Night Witch, but she only shows you a picture and you have to figure out what it means.
There are also two recipes (Aphrodisiac, Love Potion) the Day Witch teaches you, but only by giving you a sort of poetic description that you have to figure out.
Not everyone likes it when someone posts the exact recipes here, but there is an old guide that has a lot of recipes in detail, including Poison Extract, Poison Bomb, Antitoxin, Aphrodisiac, and Love Potion.

You need to craft each of these recipes once and then they will appear in your craft menu.
