Torstol seed

Torstol seeds can be planted in a herb patch in order to produce grimy torstols. This requires a Farming level of 85.

Torstol seeds can be obtained as a monster drop (see below), looting a nature impling, or by pickpocketing Master Farmers.

Planting torstol seeds can be profitable, so therefore players are advised to make sure that the herb does not die. Supercompost (or Fertile Soil spell) is strongly recommended, as this is the best way of reducing the chance of your herbs from becoming diseased, as it is not possible to water the patch, or ask a farmer to tend the herbs.

The following table shows the profit yield, assuming all the herbs and seeds are purchased/sold at the Grand Exchange, for medium price. If the herb dies, you will lose coins.

Note: Supercompost yields a minimum of 5 herbs.

Market
Torstol seeds have increased in price significantly in the Grand Exchange since the Herblore Update in October 2009, due to Torstol's use in making Overload potions. Torstol seeds currently cost, whereas in September 2009, Torstol seeds were worth about 17k each. In the same time frame, Clean Torstol weeds have increased in price from about 3k each to 35k+ each.

Farming Torstol has become more profitable than it used to be but at the same time risky since herb crops can always die and the seeds have a high cost. The possible profit, however, had grown near Snapdragon's and even surpassed it.
