I suspect the gold method has more to do with the heat created from the friction. But, if believing it's the gold helps, then that just puts more umph into the method for the person. Mind and body are connected, even this skeptic can see that.
It's been awhile since I've had one, but I remember hot as I could stand wet washclothes working well to bring it to a head then draining away. The antibiotic cream would be a good follow up I'd think, since a stye is an infection. But, having said that I've never had a doc prescribe me one.
