Grimy torstol detail.png

A grimy torstol is a herb that has not yet been cleaned to make a torstol. Grimy torstols may be grown from a torstol seed with a farming level of 85, granting 224.5 experience per herb during harvest. Cleaning a grimy torstol requires a Herblore level of 75 and gives 15 herblore experience. Clean torstols are used to make Super combat potions with a herblore level of 90 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.

One grimy torstol plus 8 other grimy herbs can be obtained from the Sinister chest in the Yanille Agility dungeon when unlocked with a Sinister key.
