noun: an element that occurs at very small quantities in the body or soil but is nonetheless important for many biological processes
A trace element, also called minor element, is a chemical element whose concentration (or other measure of amount) is very low (a "trace amount"). They are classified into two groups: essential and non-essential. Essential trace elements are needed for many physiological and biochemical processes in both plants and animals. Not only do trace elements play a role in biological processes but they also serve as catalysts to engage in oxidation and reduction mechanisms.
The exact definition depends on the field of science:
In analytical chemistry, a trace element is one whose average concentration is less than 100 parts per million (ppm) measured in the atomic count or less than 100 micrograms per gram.
In biochemistry, an essential trace element is a dietary element that is needed in very minute quantities for the proper growth, development, and physiology of the organism. The dietary elements or essential trace elements are those that are required to perform vital metabolic activities in organisms. Examples of essential trace elements in animals include Fe (hemoglobin), Cu (respiratory pigments), Co (Vitamin B12), Mn and Zn (enzymes). Some examples within the human body are cobalt, copper, fluorine, iodine, iron, manganese and zinc. Although they are essential, they become toxic at high concentrations. Elements such as Ag, As, Cd, Cr, Hg, Pb, and Sn have no known biological function, with toxic effects even at low concentration.
In geochemistry, a trace element is one whose concentration is less than 1000 ppm or 0.1% of a rock's composition. The term is used mainly in igneous petrology. Trace elements will be compatible with either a liquid or solid phase. If compatible with a mineral, it will be incorporated into a solid phase (e.g., nickel's compatibility with olivine). If it is incompatible with any existing mineral phase it will remain in the liquid magma phase. The measurement of this ratio is known as the partition coefficient. Trace elements can be substituted for network-forming ions in mineral structures. Trace elements that are not essential to a mineral's defined composition will not appear in the chemical formula of that mineral. https://en.wikipedia.org/wiki/Trace_element
If such ennobled water is drunk, which accumulates normally insoluble trace-elements in a 'released' state and binds its oxygen content up to a maximum of 4%, then the dissolution of normally insoluble sediment accretions takes place, enabling sclerosis, encrustation of the blood, sap and lymph vessels to be healed. The organisms thus treated regain their metabolic functions as well as their reproductive abilities. In this way senile men almost fully recover their virility. After extended consumption of regenerated drinking water, even people who wear glasses can use weaker ones, because the capillaries of the eye, which supply it with high quality nutrients, will be purged of deposits. Rheumatic disorders are cured within a short space of time, for through this general detoxification the joints move freely and painlessly again and are provided with a film of essential oils. Kidney and gall stones also dissolve after only a few weeks of drinking such healing water and are passed out in gravel-like form with the urine. All those suffering from cancer can get relief from their tearing pains almost immediately, because the almost oxygen-free water binds the excess oxygen in the blood, thus eliminating dangerous hyperacidity. It is therefore not only possible to prevent cancer in this way, but even to cure this dreadful disease, if this all-healing water is drunk in good time. The healing of rheumy eyes with the aid of gold earrings also occurs in a similar way. Situated in the earlobes - the coolest location, they function bio-catalytically and make any form of water secretion impossible. If one burns one's finger, then almost intuitively one grasps the earlobe, where the relatively strongest falling temperature gradient prevails, and an almost instantaneous relief from the burning sensation is felt. Catalysts in the form of the emanations from gold and silver not only function oligodynamically (they kill pathogenic bacteria), but also build up apathogenic bacteria, as happens in the vicinity of high springs. Having recognised this, a very open-minded doctor, the director of the old peoples' home at Lainz near Vienna, attempted to cure the sclerotic symptoms of seriously rheumatic W.W.II soldiers by administering the finest gold and silver dust. He only achieved a partial cure, however, because this can only be done with the infusion of precious metals in an organic state.
 This is slightly equivocal and can be interpreted in two ways: Either 4% of the 100% oxygen content is bound, or, up to 4% of the 100% oxygen content is bound, namely 96%. In view of what has been stated in "The Liquefaction of Coal by means of Cold Flows" on p. 95 of this book, it would appear that the latter interpretation is what is intended here. — Ed.

The raw material for these atomic developmental products are the earthly remains of former life. Above all, it is the concentrates of fatty-matter which, regardless of any external positive temperature influences, solidify after death. These are subjected to fermentation processes similar to those taking place in the stocks of fatty-matter in plant juices from which, depending on the type of motion and excitation, various acids evolve that give further rise to essential and energetic concentrates. This only happens if no vessels are used, wherein annihilating fire robs these concentrates of their allotropic (polymorphic) trace-elements, namely their concentrates of essential oils, which in such high-grade fermentation processes act like yeasts.

the alteration of the above fermentation process at its most fundamental phase. To make this even clearer: Allotropic oxygen conformations are liberated through pressure- and heat-intensifying dynamic effects or volume-enlarging thermal influences, because the fat-concentrates with opposite polarity become inactive and are maintained in a passive state under such influences. This results in the inner fission (dissociation) of the previously internally interconnected and highly evolved, therefore extremely pressure- and heat-sensitive trace-elements, which like yeasts initiate the process of raw-material transformation - the fermentation process described above.
