Clean erzille is a herb used in Herblore Habitat. It is made by cleaning a grimy erzille, which requires 54 Herblore. Being untradeable in all forms (seed, grimy, or clean), 58 farming will be needed. It is used, along with a corrupt vine (obtained from diseased jadinko), to make a juju hunter potion. A step by step guide to the potion can be found here.
