In ancient India saints used to store and drink water from copper utensils. Copper in small quantity required for haemoglobin synthesis and activation of some body enzymes.
Copper sulphate is still in use in hospitals in India to check unwanted growth of tissue in a healing wound.
This recent trial proves the anti-bacterial potential of it in preventing hospital acquired infections.
Copper kills 97 percent of hospital ICU bacteria: study
The study, presented at the World Health Organization‘s 1st International Conference on Prevention and Infection Control (ICPIC) in Geneva, Switzerland, on Friday, backed what research teams at three U.S. hospitals suggested four years ago: replacing the most heavily contaminated touch surfaces in ICUs with antimicrobial copper will control bacteria growth and cut down on infection rates.
