Rhodium: Associated with the thymus.
Early research has shown that rhodium has a positive effect on tumors in mice. Much research has been done to analyze why it had positive effects. Later research has determined that mismatched DNA is associated with carcinogenesis. Studies have shown that rhodium will bind with mismatched DNA and inhibit the damage associated with these cells.
Interestingly, the ingredients sheep sorrel and slippery elm in Essiac Tea both contain rhodium.
