The entire theory of the Biochemic system (Tissue - Cell Salts) of medicines is based on the fact that the structure and vitality of organs depend upon certain necessary components in appropriate proportions. These are the inorganic salts that play a vital role in the human body by maintaining the integrity and proper function of an organ. They are the originators, the builders, the governors and the destructors of the life phenomenon.

Dr. Schussler believed that when a human being is reduced to ashes by heat, there are only twelve minerals left. He called these "the tissue salts". They are responsible for the natural balance and vitality of the body. Normally, there are different inorganic salts present in variable proportions in the body, performing their respective functions.
 

EXAMPLES

Natrum-mur or sodium chloride is a constituent of every liquid and solid part of the body. It is the most important of the chemical substances found in the blood plasma, being present in the proportion of about 0.7% (in the blood plasma in the body). 

Kali-mur or potassium chloride is found in the blood in greater quantity than any other inorganic salt. Concentration of Potassium in plasma is 20 mgms%, in corpuscles 440 mgms%, in whole blood 200 mgms% and muscles 250-400 mgms%. 

Calcarea-phos or calcium phosphate constitutes 57% of the bone.

According to him, deficiency of any of these tissue salts produces a diseased condition in the human organism, and replenishment or supplementation of the deficient salt, in physiological doses, restores health in the organism.

A deficiency of these cellular salts in a human body causes disturbance in the molecular motion of the salt in living tissues, eventually resulting in disease. Replenishing this deficiency with the appropriate salts restores the disturbance of the molecular motion of the salt and rectifies the corresponding dysfunction of the tissue and ultimately the organ. Schussler potentised the tissue salts and made them into biochemic remedies for administration.

Let us understand this in a simple way by considering the example of a plant. Blood is to the human body what soil is to a plant. For a plant to thrive well, the quality of soil around its roots must have all the essential substances in the right proportions. If any substance is deficient in the soil, it will produce a weak plant. In agriculture, when this deficiency is supplemented in the form of a organic fertilizer, the weak plant starts to flourish.

Similarly, when the human blood is deficient of the necessary constituents, the cells that depend on the constituents of its nutritive neighborhood are deprived of the nutrition, which leads to weak and sick bodies susceptible to diseases. When the appropriate tissue salt replenishes this deficiency in blood, it leads to the restoration of the sick individual's body.

CONCEPT OF HEALTH
The Health may be considered as the state of stable equilibrium of the ionic movement of the inorganic salt in the living cell. According to the definition of the German pathologist Virchow, 'Health is normal cell metamorphosis' i.e. destruction of old cells and regeneration of newer ones.

A human body is composed of two kinds of matter- organic and inorganic. For normal tissue building both kind of substances are needed. These constituents are necessary for the normal functioning of the cell and are supplied through blood for the nutritional requirements of the tissues. Blood is a medium, which consists of sugar, fat and albuminous substances as organic substances and inorganic substances in the form of water and salts like chloride of sodium, chloride of potash, fluoride of lime and many other. 

But water and organic substances are useless without the presence of the inorganic cell-salts. These salts use the organic matter and water for tissue building and are responsible for the generation of new cells and a harmonious functioning of all the tissues and organs in the body.

The presence of these constituents or inorganic salts is vital for the proper growth and development of every part of the system. In normal conditions if there is any loss of these nutrients it is furnished in the necessary locations and in appropriate amounts by the digestion of food and drinks that we consume so that there is no imbalance in the molecular motion of the salt. 

This normal functioning is responsible for the constructive, building process of new cells and destruction of the old cells simultaneously, as well as for the removal of the waste material from the body. Hence 'Health' is defined as a state of being that is typified by normal cellular metamorphosis.

CONCEPT OF DISEASE
The Disease is a state of disequilibrium of the normal ionic movement of the inorganic cell salt. According to Virchow's definition, 'Disease is an altered state of the cell'. It is caused by the imbalance of the molecular motion of one of the inorganic tissue salts.

In a normal functioning cell, each and every cell is capable of absorption or elimination of certain substances. Disease results if this functioning of the cell is reduced or rendered dormant for the time being, because of the loss of one of its salts. When there is lack of one or more of these inorganic salts, the cell loses its normal functioning of absorption or elimination of unwanted products giving rise to abnormal conditions, which are termed as diseases. Diseases are manifested as symptoms in different ways and different locations according to the specific deficiency of the tissue salt.

Symptom is nothing but an indication of this deficiency, a signal by Nature that a particular part is in danger and requires a particular element for safety or restoration. Once this deficiency is recompensed by providing a plentiful store of homogenous material from the neighboring nutritive medium, the equilibrium is restored once again and health is established. The cells can now resume their normal function and recommence the elimination of waste products with the means of various chemical processes.

Biochemic system does not consider the presence of bacteria, virus or fungus as disease, but takes into account the symptoms produced due to deficiency of a salt and remedies are given accordingly.

CONCEPT OF CURE
Cure is obtained by supplying the requisite proportion of inorganic cell salt to maintain the equilibrium of ionic movement in the cell.

It can be achieved when the molecular imbalance is restored by administration of minimal remedial dose of the deficient inorganic salt. The salt thus furnished refills the breach in the chain of molecules of the affected cell or tissue salt and restores back its normal functioning. For e.g. the clinical condition of 'rickets' in children shows the deficiency of 'phosphate of lime' in the bones due to the imbalance in the molecular motion of this salt. By replenishing the salt in appropriate proportion the molecular imbalance is restored and brings about cure of rickets

The Biochemic remedies assists the body's natural efforts towards cure by supplementing these tissue remedies that are deficient in certain tissues, thus leading to correction of the derangements in the physiological chemistry. In other words, the Biochemic remedies correct the deficiency directly, unlike other therapies that use medicinal substances, which are heterogeneous to the constituents of the body, to indirectly achieve cure.
