Grimy ardrigal is a herb that is obtained by searching for the palm trees located north-east of Tai Bwo Wannai in Karamja, near the coast of the Harpie Bug Swarms. It can be cleaned to obtain clean ardrigal. It is the second herb Trufitus asks players to bring him during the Jungle Potion quest. This herb is used to make the bravery potion in Legends' Quest. If players "use" the clean herb on Trufitus after the quest, he'll give players a few coins for it.
