Toxin is the substances living organisms reject. They are usually kept in internal organs of domestic animals. Eating cheap animal organs is akin to consuming the accumulated (toxic) substance in a used water filter.
The natural healing force within each one of us is the greatest force in getting well.
The body initiates an intensive cleansing process when the amount of toxins & debris reaches a dangerous level, and they claim it's a disease caused by a microbe. Then they introduce highly toxic chemicals into the body that paralyze its efforts and the symptoms abate, and they claim it's because they destroyed the microbe.
All erroneous assumptions based on a lack of understanding of the body and its ways.
