Torstol is the highest level herb, which requires level 75 Herblore to clean and yields 15 experience. Torstol can be grown in herb patches at level 85 Farming.
Obtaining a Torstol is difficult as they can only be obtained by Farming, nature implings, or dropped rarely by Zulrah and the Kalphite Queen. Alternatively, They can also be obtained(in grimy form) from the Sinister chest, Skotizo, Cerberus, and the Chambers of Xeric.
