Dr. Schuessler theorized that the human body contains twelve essential vital minerals/salts, the proper balance of which is essential for normal cell function and for maintaining good health. When the cellular balance is disturbed, an abnormal condition follows, leading to various diseases. According to Dr. Schuessler, a normal balance of these vital salts can be restored by administering the deficient mineral salts in an easily assimilated form. These are now known as Schuessler's tissue salts. Dr. Schuessler found that the most effective way to assimilate these salts was through a homeopathically prepared microdose, which passes quickly into the bloodstream and therefore into our cells.
If the blood does not have the necessary quantities of these active, life-giving, inorganic elements, then the rebuilding process cannot proceed in a normal manner and this causes a disorder or disease of the body.
