The world's oldest medical texts, the Eber Papyrus, states, "Treat inflammation
with pulverized copper". Today, thousands of years later, pharmacies
around the world offer copper bracelets as a safe first aid for joint pains.
"Copper, when in contact with the skin, forms chelates with human sweat
(sometimes seen as green deposits) and is thus absorbed through skin."
"Copper chelates are more effective and less toxic than drugs being used
to treat arthritis."
Green wrist occurances vary depending on the body chemistry of the wearer
and, if desired, are easily washed off. Many expect an occassional green mark
to show that the copper "is working". Copper combines with sweat,
and forms compounds called chelates which are assimilated by the body. Green
deposits occur when chelates are formed faster then they are absorbed. This
phenomenon increases with stress and it can be intrepreted as an early warning
to slow down.
