As claimed on page 33 of this MMS book:
All pathogens (poison producers) have a negative ORP.
All beneficial bacteria have a positive ORP.
In other words:
The beneficial bacteria are positively charged.
Human tissue cells also have a weak positive charge.
Are these valid claims?
Additional clarification of the terminology:
All organisms and body cells and even liquids have an ORP (Oxidation Reduction Potential) that can be either positive or negative. The ORP is the electrical charge that cells exert on other things in their immediate environment. Oxidizers also have an ORP, mostly called Oxidation Potential, and all oxidizers have a positive potential.
Pathogens create a waste material that is poisonous to the body.
Beneficial bacteria do not generate any poisonous material.
