Because you will literally feel like hell warmed over on powerful natural Antibiotics like neem oil, oregano oil, etc if you are in a very toxic body.
Have your use of activated charcoal well-practiced before you bring out your weapons, then you'll prevent yourself getting damadged when you start the battle. :)
(Aka, dieoff can damage, minimize it as much as possible!)
DMSO breaks down into formaldehyde when the body has to process it, MSM lignisul cream/powder is much kinder on the body.
Colloidal Silver at 10 PPM is perfect for an internal antibiotic, if you're disciplined and regular at taking it like clockwork.
Coconut oil at 3tblsp to 1-2 drops oregano oil should do the sores well. That's a good starting dilution for oil pulling/mouth rinsing with the mix, too. If you start to swallow some, that's when you'll want the activated charcoal at 1/2 tsp-1 tablespoon dose in water. (Depends upon how severe the situation is!)
While cleansing, drink seriously lots of water (!)
