[@Banana] I still think the healing sap is a bit to versatile. I would say, do away with healing illnesses, magical or otherwise, and instead make it a magic salve that, when applied to a wound accelerates healing and prevents infection. It could be used to treat cuts, burns, bruises, natural poisons, and the like. I'm going to have to say no to restoring lost body parts, whether they be lost limbs or lost eyes. I think this would make it a highly useful power without making it too versatile.
