An adult human body weighing 70 kg contains about 0.2 milligrams of gold. It’s been found that the element plays an important health function, helping to maintain our joints, as well as facilitating the transmittal of electrical signals throughout the body.

Silver is a white lustrous transitional metallic element found widely in the human environment. Low concentrations of silver are present in the human body through inhalation of particles in the air and contamination of the diet and drinking water, but silver serves no trace metal value in the human body.

Yes! This is will most definitely work, if you don’t have Coke on hand, you can use similar carbonated cola drink and it will work just as well.

Silver’s antibacterial and antifungal properties have been known for centuries. It’s the basis for the old wives’ tale that putting a silver coin in your milk would stop it from growing bacteria and spoiling. If curdled milk makes you queasy these videos may trigger unpleasantness).

Silver prevents bacteria and algae from building up in their filters so that they can do their job — getting rid of bacteria, chlorine, trihalomethanes, lead, particulates and odor. Silver ions are being added to water purification systems in hospitals, community water systems, pools and spas.

In her Stanford laboratory, Alia Schoen purifies water using a new method thousands of times faster than anything previous. It uses nanotechnology and silver. In the days before milk could be pasteurized or refrigerated, people would drop a silver coin into a bottle to preserve it. Silver is lethal to bacteria.

Egyptian writings are known to mention the use of silver. The Greeks and Romans stored liquids in vessels crafted out of silver in order to prevent spoilage and to keep bacteria from. The coins kept the water safe from bacteria and algae and kept the milk fresh.
