Boosted Healers are a powerful type of healing potions made from the combination of both Herbs and Herbal Boosters. They are introduced in Mortal Kombat Mythologies: Sub-Zero.
The alchemical mixture of a Herbal healer and a Herbal Booster results in a boosted healer, which will completely replenish the user's life forces.
Sub-Zero the Elder uses these potions to vastly heal himself during his quest for the Amulet of Shinnok.
