chronic – a condition which persists over a long period of time

coagulation – the transformation of a liquid into a soft, or semi-soft, solid mass


colloidal Copper
 – true colloidal Copper, such as MediCOPPER, consists of nanometer sized Copper particles evenly dispersed and held in suspension within a liquid (usually water) due to the net charge on the Copper nanoparticles and their interaction with the liquid

colloidal Gold – true colloidal Gold, such as MediGOLD, consists of nanometer sized Gold particles evenly dispersed and held in suspension within a liquid (usually water) due to the net charge on the Gold nanoparticles and their interaction with the liquid

colloidal Platinum – true colloidal Platinum, such as MediPLATINUM, consists of nanometer sized Platinum particles evenly dispersed and held in suspension within a liquid (usually water) due to the net charge on the Platinum nanoparticles and their interaction with the liquid

colloidal Silver – true colloidal Silver, such as MediSILVER BLACK, consists of nanometer sized Silver particles evenly dispersed and held in suspension within a liquid (usually water) due to the net charge on the Silver nanoparticles and their interaction with the liquid

colloidal Zinc – true colloidal Zinc, such as MediZINC, consists of nanometer sized Zinc particles evenly dispersed and held in suspension within a liquid (usually water) due to the net charge on the Zinc nanoparticles and their interaction with the liquid

colloid stability – the stability of a colloidal suspension of nanoparticles in a polar liquid, such as water, due to the mutual repulsion that exists between the nanoparticles and the attraction that exists for the nanoparticles by the polar liquid

compound – a pure substance consisting of two or more different elements that can be separated into simpler substances through the use of chemical reactions 

element –  a pure substance that cannot be broken down into simpler substances

elemental Copper – Copper in its natural metallic, rather than ionic, state

elemental Gold – Gold in its natural metallic, rather than ionic, state

elemental Platinum – Platinum in its natural metallic, rather than ionic, state

elemental Silver – Silver in its natural metallic, rather than ionic, state

elemental Zinc – Zinc in its natural metallic, rather than ionic, state

Gold deficient – a condition in which the micro-nutrient requirements of the mineral Gold is deficient within living tissue

heavy metal – The label “heavy metal” does not refer to the density or atomic mass of a metal, but instead refers to metals that are dangerous or toxic.  There is no standard by which a metal is designated as a heavy metal – a heavy metal is a toxic metal.  Though most heavy metals have a high atomic number, atomic weight, and a specific gravity greater than 5.0, there are some lighter metals and metalloids which, because they are toxic, are deemed heavy metals; and yet some metals which are indeed heavy, such as Gold, are not toxic. Heavy metals include some metalloids, transition metals, basic metals, lanthanides and actinides. Examples of heavy metals include Lead, Mercury, Cadmium, some forms of Chromium. Metals such as Iron, Copper, Zinc, Aluminum, Beryllium, Cobalt, Manganese and Arsenic have been deemed as heavy metals on occasion, but many may disagree with this; we need Iron, Copper and Zinc in our diet – so how toxic can they be?  Gold, platinum and other high density metals are not “heavy metals” in terms of this usage. Lead fillings are toxic, while Gold fillings are not. Lead will give you heavy metal poisoning – Gold ( although it has a much higher density – will not give you heavy metal poisoning and is indeed not classified as a “heavy metal”.

ion – an atom or molecule in which the total number of electrons is more, or less, than the total number of protons – more resulting in a negatively charged ion (anion) or less resulting in a positively charged ion (cation)

ionic Gold – A solution consisting of water and gold ions (dissolved gold) usually in the form of Au+3 ions, with chloride being the companion anion.. Contains no gold particles and does not exhibit a Tyndall Effect. Ionic gold has been reported to be neurotoxic which means it is toxic to nerve cells. Gold (III) chloride (ionic gold) is potentially harmful to humans if ingested. See the Material Safety Data Sheet (MSDS) for gold chloride for more information on toxicity.
Ionic gold should not be confused with colloidal gold which consists of metallic gold particles and is not harmful to humans.

MediCOPPER – the trademarked brand name of solution consisting of 99.99+% pure Copper as bio-available nanoparticles – colloidally dispersed and suspended in pure, pharmaceutical grade water.  MediCOPPER – the trademarked brand name of solution consisting of 99.99+% pure Copper as bio-available nanoparticles colloidally dispersed and suspended in pure, pharmaceutical grade water.
