Limpwurt root

Limpwurt roots are very special roots. With 12 Herblore and a Tarromin herb you can make a 3-dose regular strength potion, or you can make a full 4-dose potion with absolutely no herblore level required. However, instead of Tarromin, you need red spider eggs and a couple of gold pieces. There is an apocathery in Varrock that will brew this potion if you give him the necessary items. Limpwurt roots, like most herblore items, are dreadfully expensive, so only buy them if you wish to boost up your herblore level. As an alternative to paying for them, they are drops from hobgoblins and hill giants, and, with the necessary herblore level, you can grow your very own roots in a farming patch.
