Clean ranarr (pronounced Ran-ARR) is a grimy ranarr that has been cleaned. It is the fifth lowest level herb available, but it is a highly-traded herb as it is an ingredient in the widely used Prayer potion.
On 20 August2009, a large price-manipulation clan bought out Ranarrs, Ranarr potions, prayer potions, and super restore potions. This resulted in a large spike in price and rants on the forums. This only lasted 4 days, and in those 4 days, the price of Ranarr herbs went up 5-6k.
Ranarr herbs were originally known as 'Ranarr Weed', the date on which they were changed is unknown. Some NPCs still refer to ranarr as ranarr weed. They were also referred as ranarr weed when cleaning them.
