Grimy avantoe

A grimy avantoe is a herb that has not yet been cleaned to make a clean avantoe. Grimy avantoes may be grown from an avantoe seed with a Farming level of 50. It is also dropped by certain NPCs. Cleaning a grimy avantoe requires a Herblore level of 48 and gives 10 Herblore experience. Clean avantoes are used to make fishing potions, super energy potions, hunting potions and added to a super attack potion to make an extreme attack potion. Avantoes may also be obtained from the Sorceress's Garden minigame.

Cleaning grimy avantoe yields a profit/loss of coins per herb.
