Iridium is a chemical element with the atomic number of 77 and
the second densest element (after osmium) and is the most
corrosion resistant metal, even at temperatures as high as 2000 °C.
Iridium is found in meteorites with an abundance much higher than
its average abundance in the Earth's crust.
In the human body
iridium acts as a powerful antioxidant that stabilises the body’s
metabolism and destroys free radicals. Free radicals are what cause
the human body to decay, breakdown and become susceptible to viral
and bacterial infections. It has been said that iridium may also be involved with processes that
are associated with the spinal cord and pituitary gland although scientists have yet to prove it.
