If you have ever done the quest Allakhazam.com: World of Warcraft: Quest: Goldenmist Village, then you receive 5 Special Goldenmist Brew. Now what this brew does is gives you a bonus 70 health, not 7 stam, 70 health. Say your out of potions, and are about to die, pop this potion while under 70 health and you will gain 70 health, giving you some extra time to think of a way to get out.
if you already know this, im sorry, this may be common sense, i searched and didnt find anything
