Grimy torstol

A grimy torstol is a herb that has not yet been cleaned to make a clean torstol. Grimy torstols may be grown from a torstol seed with a farming level of 85, which is dropped by certain NPCs. Cleaning a grimy torstol requires a Herblore level of 75 and gives 15 herblore experience. Clean torstols are used to make Overload potions with a herblore level of 96 or Zamorak brews with a Herblore level of 78. Grimy torstol is one of the five herbs that cannot be obtained from the Sorceress's Garden.

Grimy torstol has been worth less than clean torstol in the past because clean torstol updates in price more frequently than grimy torstol. However, as of February 2010, they both fluctuated in price at around 25-35k after a steep increase in price with the release of the Overload potion.
