According to Ayurveda water stored in a copper vessel has the ability to balance all the three doshas in your body, (vata, kapha and pitta) and it does so by positively charging the water.Here are the health benefits:Can kill bacteria;Stimulates your brain;Beats arthritis and inflamed joints;Helps the digestive system perform better;Beats anaemia;Helps heal wounds faster.Washing:Do not use a coarse scrub to wash the inside of the vessel as it will tend to scrape away copper from the vessel.Instead, use one half of a lemon (you can squeeze out the juice) and rub it on the inside of the vessel. Allow it to stand for a few minutes and then wash off with plain water. Alternatively you could also try using baking soda with water. Use this mixture to coat the inside of the vessel and allow it to stand for a few minutes and then rinse away the excess baking soda.
