Yes, I'm a Christian, druid boy, and no, GOD doesn't provide a manual. He knew we would figure it out. Did the trees tell you what to do with iodine? I could tell you what to do with it, but I'll let you figure it out for yourself.
And by the way, if you have a sick one, figure out what it's called, especially before you tell people how to treat it. Calling it by the wrong name just takes all the validity of your claims away.
