I am newbie to all of these too.
But my first surpise was the use of H2O2. I was amazed. I drink it and my reflux and my stomach felt immediately well. Also I used it to moles and it worked. But it was a little strong. It killed everything I am afraid of leaving white spots and scars.
Then by luck I found iodine. It was a lot milder to everything. Then I searched more and I found curezone. I think Iodine is closer to our body. I still wait my Lugol from jcrow to start using it. So long I use tincture. I don't believe it is so hazardous but Lugol is better ( no alcohol).
In conclusion H2O2 (Hydrogen-Peroxid) works wonders but I am afraid is too strong. I think our white cells use it for virus and fixing problems only. Not to feed with oxygen the other cells. The best way is whatever you choose to make it with caution and see how will your body react. In my opinion Iodine is far better.
