Cactus spine

Cactus spines are a produce grown from a cactus seed at level 55 Farming for use in the special cactus patch in Al Kharid. They may be harvested from a fully grown cactus for 25 farming experience for each spine.

One spine takes about 25 minutes to grow for a maximum of 3 spines on the cactus at once. If the player has completed the hard Desert tasks, players will harvest 2 spines for each harvesting action, for a maximum of 6 spines. This may be increased by the passive effect of a summoned giant ent familiar.

Cactus spines may be used with a vial of coconut milk to create Weapon poison+ (unf), which can be used along with red spiders' eggs, to make weapon poison+ with the Herblore skill.

Players may also pay a farmer 10 spines to care for a yew tree, but this is not recommended because of the spine's high cost compared to a yew seed.
