Well, an autoimmune disease is caused by your own immune system being so ramped up that it attacks your own body...so the cure would be found in whatever will put your immune system back in it's proper place and function.

But first, what caused it to ramp up to begin with?

Probably some kind of chronic inflammation.

So I would say go on a long term course of anti inflammatories or naturally anti inflammatory foods until the symptoms abate.

Then take a maintenance dose of Lugols iodine for the rest of your life...along with eating celery daily and using nothing but coconut oil for cooking and baking.

Good luck.
