Not OP, but I have done this for allergies. N. Americanus, 10-15 eggs at a time. No side effects other than an awful itch 12-36h after administration. Been great for my allergies. I've cut way down on fexofenadine. I also live with a cat and a poodle and only really feel symptoms if I literally rub my face in the cat, or groom the dog inside without a mask.
