Health may be considered to be the state characterized by normal cell metamorphosis; thus, when by means of digestion of food and drink, recompense is made to the blood for the losses it sustains by furnishing nutritive material to the tissues, this compensation is made in requisite quantities and in proper places, and no disturbance of the motion of the molecules occurs. Under these conditions alone will the building of new cells and the destruction of old ones proceed normally, and the elimination of useless materials be furthered.

Disease is the result of a disturbance of the molecular motion of one of the inorganic tissue salts. The cure consists in the restoration of the equilibrium of the molecular motion by furnishing a minimal dose of the same inorganic substance, since the molecules of the material thus used remedially fill the gap in the chain of molecules of the affected cell or tissue salt.

Virchow says that disease is an altered state of the cell, and hence the normal state of the cell constitutes health. The constitution of the cell is determined by the composition of its nutritive environment exactly as a plant thrives according to the quality of soil around its roots.

In agricultural chemistry we add as fertilizer that element most lacking in the soil. But three essential substances used as fertilizers are required, namely, ammonia, phosphate of lime or potash. The other substances needful for plant nutrition are found in sufficient quantities in the soil. The same law of supplying a lack applies to biochemical remedies; for instance, take the following example:

A child suffering with rickets shows a lack of phosphate of lime in the bones due to a disturbed molecular motion of the molecules of this salt. The quantity of phosphate of lime intended for the bones, but failing to reach its goal, would accumulate within the blood were it not excreted by the urine, for it is the office of the kidneys to maintain the proper composition of the blood, and therefore to cast out every foreign substance or surplus supply of any one constituent Now after the normal molecular motion of the phosphate of lime molecules is again established within the involved nutritive soil by administering small doses of the same salt, the surplus can again enter the general circulation and the cure of the rachitis be brought about.

Every normal cell has the faculty of absorbing or rejecting certain substances. This property is diminished or suspended when the cell has suffered a loss in one of its salts in consequence of any irritation. As soon as this deficiency is made good by a supply of a homogeneous material from the immediate nutritive soil, the equilibrium is re-established. But if the supply is not offered spontaneously, it is to be assumed that the needful salt is lacking in quantity, or, on the other hand, that the diseased cells have suffered a physical alteration besides, which precludes the entrance of the required tissue salt. In such a case the salt must be offered in a more diluted state, that is, a higher trituration.

If the altered cells regain their integrity by recovering their loss, they can again perform their normal functions, and bring about the removal by chemical processes of morbid products, exudations, etc. The biochemical therapeutics aids nature in her efforts to cure by supplying the natural remedies lacking in certain parts, that is, the inorganic cell-salts, and in this way corrects abnormal states of physiological chemistry.

The aim of biochemistry is to cover a deficiency directly. All other methods of cure reach this goal indirectly, when they make use of remedial agents heterogeneous to the constituents of the human organism.
