"Shelley said that she felt that people could regain full health by cleansing whilst still have amalgams."
Mercury is one of the most toxic substances known to man. Placed in a humans mouth, it is a constant source of toxicity which feeds the body so a person cannot ever reach optimal health. Mercury toxicity is a huge load for the immune system and it it very toxic to all cells. But then I look to real human potential for the model of optimal health, not the average joe walking wounded which is the "norm" for our dumbed down, medically dependent culture. For instance, Dr. Gabriel Cousens did 600 pushups on his 60th birthday.
There is alot you can do to take your total toxic load down to help detox prior to Amalgam removal. A raw diet is a great start.
