I just want to share my experience. I’ve done some research and learned that copper is great for fighting against viruses. I’m not claiming anything but sharing my experiences. I’ve felt like a cold sore or maybe even a sore throat that was about to happen to me. I put the pure copper onto the receiver side on my scalar device and sat in the middle. It cleared it up in a couple of hours. Give it a shot. Who knows what else it can clear.
