The Old School RuneScape Wiki also has an article on Poison antidote.

A Poison antidote is a potion that can be made with the herblaw skill. It requires level 48 herblaw to make and gives 106.25 experience. When consumed, it cures the player from poison and provides protection from poison for about 6-12:30 minutes.

To make a Poison antidote, first add a Irit Leaf to a vial of water , then mix in a ground unicorn horn. As with most potions, you initially make 3 doses of the potion and the doses decrease as you drink them.
