Gold is the ultimate precious metal and has been coveted for its use in jewelry. But its true value may lie in its health benefits. Dating back to the Egyptian use of this metal for its anti-aging properties, it was also cherished for its mental focus enhancing abilities and as a mood up-lifter. According to recent studies demonstrated that ingesting colloidal gold liquid increased a subject's IQ by four points. The colloidal gold contained in these soap bars are made with 24 karat gold and is the same colloidal gold that's being used in the formulation of some of Europe's most elite anti-aging cosmetics and facial creams.
