Grimy ugune is a herb used in Herblore Habitat. It is made by planting ugune seeds in a vine herb patch. Cleaning grimy ugune requires a herblore level of 56 and gives 11.5 herblore experience, producing clean ugune.
Clean ugune herbs are used, along with a marble vine, to make a juju farming potion. If you already have a Juju Farming Potion it is highly recommended to drink a dose when harvesting the herb as the dose easily pays for itself.
