It’s a good question, but I don’t, as I'm not a trained naturopath. If you wanted those kind of solutions seek out an experience veterinary naturopath. They will help you figure out why the excessive scratching exists in the first place, as without knowing that it’s just all guess work. And guess work sucks. With regards to the hyperthyroid, I have no first hand experience with naturopathic treatments for that. What ever you try, just test it. It’s easy to make sure the thyroid levels drop.
