Grimy irit

A Grimy irit is a herb that has not yet been cleaned to make a Clean irit. Grimy irits may be grown from a irit seed with a farming level of 44. It is dropped by certain NPCs. Cleaning a grimy irit requires a herblore level of 40 and gives 9 herblore experience. Clean irits are used to make super attack potions, super anti-poison potions and super strong anti-poison potions with herblore levels of 45, 48 and 79 respectively. Grimy irits can also be obtained from the Sorceress's Garden minigame.
