Irit

An Irit herb can be identified at level 40 herblore, and it is used to make super ani-poison potions and super strong anti-poison potions.
A popular method to obtain irit herbs is by killing chaos druids in Taverley Dungeon or in the wilderness part of the Edgeville Dungeon , just west of the level 10 thugs . 
Alternatively, you can acquire a decent amount of irit leafs from the farming skill. To plant the seeds, you need 44 farming.
