Herb Gathering

Interesting fun fact: This is affected by haste.

With 482 haste, my cast time for gathering herbs is 4.23s. The more you know :)

With gathering professions now comes new passive and cast abilities. Herbalism now gives you the ability "Lifeblood". With each rank up in Herbalism, you obtain a new rank in this skill.
Lifeblood is a very useful skill that you can cast. This is a self only heal, which is instant. Upon casting this, flowers will sprout around your character and you will be healed over time. The amount in which you are healed is increased with your skill/rank level.

Here are the different ranks for this ability in order of ranks and herbalism skill:
