This article is about the grimy herb. For the cleaned herb, see Ardrigal
Grimy ardrigal is a herb that is obtained by searching the large palm tree on the north east area of Tai Bwo Wannai of Karamja near the Harpie Bug Swarms. It can be cleaned to obtain ardrigal. It is the second herb Trufitus asks you to bring him during the Jungle Potion quest and is also used in the Legends' Quest. As of now, this herb is not used in any potions, although if you "use" it on Trufitus after the quest, he'll give you a few coins for it.
It cannot be identified until you have finished Jungle Potion. Cleaning this herb gives 2.5 Herblore experience.
