Refreshing Herb

Refreshing Herbs are items in the Mario & Luigi series used to get rid of any status ailments on the playable character, such as Poison or Fury. Refreshing Herbs resemble a four-leaf clover and can generally be bought in shops for low prices, though they can often be found in ? Blocks. They can be used in battle to quickly cure whoever has the status ailment.
