Grimy ranarr

A Grimy ranarr is an herb that has not yet been cleaned to make a clean ranarr. Grimy ranarrs may be grown from a ranarr seed with a farming level of 32. It is dropped by certain NPCs. Cleaning a grimy ranarr requires an herblore level of 25 and gives 7.5 herblore experience. Clean ranarrs are used to make defence potions and prayer potions with an herblore level of 30 and an herblore level of 38, respectively. Grimy ranarrs may also be obtained from the Sorceress's Garden minigame.

Trivia

 * Interestingly, the item itself is called "grimy ranarr". However, when a player cleans the ranarr, he or she receives the message, "You clean the dirt from the ranarr weed." This is a reference to the fact that ranarrs were once referred to as "ranarr weeds."
 * Oddly, since the beginning of June, and more noticeably towards the middle of June, grimy ranarr has been spiking in price, reaching nearly 10k coins in the Grand Exchange, compared to only 7k at the beginning of the month. This is because the PvP and Bounty World updates increase demand for Prayer Potions, or due to the Merchanting clans manipulating their price. Grimy herbs, including ranarr, are commonly found by killing chaos druids.
