I read a news in Sunday Times Of India,Chennai Edition this daty 16th November 2008 in page No 13, that Copper can cure and kill bacteria.
But it is not so., continuous use of Copper will develop gas tic trouble and if you sit in a house constructed with copper roof, will affect your lungs. It will divert the light rays and split them and direct in to the human body that will kill iron in blood.
This will give giddiness and anemic.
Further in India Some herbals are put in to the copper pot placed above 60 ft height so that the rays of the sun penetrates thro the herbal plant and send light rays in the body of human who visit the Temple.
I am having more to tell.
You must know that The Goddess shrine in Kanchi Varadharaja Perumal temple is covered with Copper wholly and the priest often gets gas problems.
Since I am doing PhD in Vedas, under a topic "Vedas- A critical analysis with special reference to human body and health", , which is purely Alchemy, practiced before 10,000 years, I read many books and studying NaNo Technology and health that mentioned in Vedas. Even this day I found in the same page that a root in china is curing Aids. But the news doesn't reveal how the dead cells are to be removed. either through motion or Urine.
They just place few Aids Cell, applied the juice of the root and found that it kills the germ, that's all. They forgot that the aids cell is supported by many other cells that will eat away the juice of the root.
