Cactus

Cactus was introduced in the 1.0.5 patch.

Cactus is a plant that only grows on sand. It can be chopped down for varying amounts of Cactus - the material - based on its size.

A cactus deals 10 damage to you if you touch one.

Cactus, when cut down and gathered up, is also an alchemical component, and is used in the brewing of Swiftness Potions and Thorns Potions.

May be harvested using an axe, blown up with Bombs or Dynamite or the block of sand underneath the cactus can be mined.
