milk splash potion

Now that improvements have been made to combat with entities, such as wolf armor or enhancements to make the horse a viable combat mount, I feel that a critical weakness for them is magic attacks via potions.
A poison potion can significantly weaken allied mobs, or in the case of horses, paralyze them upon taking damage, which can hinder their use in combat. Therefore, I propose adding a throwable potion that removes effects like those caused by milk, or a potion made with milk, to make them more viable in combat.
