If you add roe to a 2 dose antipoison it will become a 2 dose antipoison mix. This gives 12 additional Herblore experience, and requires level 6 Herblore. Adding caviar will not increase the health gain to 6 hitpoints, that being a common misconception. This mix can only be created after completing the Herblore part of Barbarian training with Otto Godblessed. When drinking a sip of the potion it says, "You drink the lumpy potion." If the player drinks all doses or empties the potion, it will become a regular empty vial.
