Replenishes blood lost through injury
- "It seems there was some rather unusual kind of poison in that snake's fangs that keeps wounds open. They're sure they'll find an antidote, though; they say they've had much worse cases than mine, and in the meantime I just have to keep taking a Blood-Replenishing Potion every hour."
- —Arthur Weasley.[src]
The Blood-Replenishing Potion is a potion that tops up the blood levels of the drinker after blood loss from injury or otherwise.
