This item can be crafted using Alchemy (275); taught by [Recipe: Major Healing Potion] before the Burning Crusade expansion, or trainable from Master Alchemist trainers in the Burning Crusade.
This potion shares the same 1 minute cooldown as all other healing and mana potions, provided the imbiber is out of combat.
The major healing potion has the same healing properties as [Volatile Healing Potion], but is more widely available and requires a slightly lower level to use.
