Cactus

Cactus was introduced in the 1.0.5 patch.

Cactus is a plant that only grows on sand, commonly seen in deserts. It can be chopped down in the same manner as trees for varying amounts of it, based on its size. It also deals 10 damage to the player when touched.

Cactus can be used in the brewing of Swiftness Potions and Thorns Potions.

May be harvested using an axe, blown up with Bombs or Dynamite or by mining the block of sand underneath it. After harvested, it cannot be placed by the player.
