Copper bracelets relieve pain and inflammation. They have been used specifically for anemia, arthritis, cardiovascular, and immune health.
“The copper bracelets were weighed before and after use. Preliminary results show that, to a significant number of subjects, the wearing of the 'copper bracelet' appeared to have some therapeutic value.”
“It has also been shown that the wearing of a 'copper bracelet' results in a weight loss in excess of the body's total burden of copper (100-150 mg). A pair of copper bracelets lost 80 mg in 50 days when worn around the ankles and a copper bracelet worn around the wrist also lost about 90 mg in that time.” https://pubmed.ncbi.nlm.nih.gov/961545/
