Copper has been used for medicinal purposes in Ancient Egypt, Greece and by the Aztec civilization. Magnets have been used in traditional Chinese Medicine for thousands of years and are still used today as a first line treatment for many common complaints. And they believed health benefits of copper include proper growth of the body, efficient utilization of iron, proper enzymatic reactions, as well as improved health of connective tissues, hair, and eyes. Magnets worn close to your joints are believed to help increase blood flow to these joints, bringing healing nutrients such as iron and Vitamin C to them. For these reasons, many people feel copper magnetic bracelets are a great way to bring natural pain relief to your life. • STORAGE AND TARNISHING EFFECT: Copper Oxidation occurs in acidic environment when it contacts with sweat gland. Green Deposit is not bad: It is a fact that our body needs copper and can get it from food like milk, nuts, seafood and yummy chocolate. If you wear copper jewelry and it leaves a green deposit, your body will also absorb it and put it at good use. For storage remove it and store it in a Velvet bag and close properly using tightening rope on it to reduce the tarnishing effect. It also helps to keep bright copper shiny i.e. remove any beginning oxidation by cleaning it regularly. Ketchup, vinegar or lemon juice works. Alternatively you can use renaissance wax to protect the jewelry though this is not the permanent solution.
