I'm not talking about healing, his resurrections isn't revivify (which require the original body), it's true resurrections. It recreate a whole new body, tadpole free.
Gale's true resurrections scroll should also cure him of the tadpole.
It should cure him of the tadpole, yes. However, I have a feeling that the writers will say "The tadpole cannot be removed in such a way, it's a special case. The power behind what is keeping the tadpole there is unique".
They may also say that it isn't a wound, poison, disease, or curse, but rather a parasite or "part of you": if you're brought back, you're brought back with the tadpole.
