Human biology is governed by countless intricate biochemical mechanisms (metabolism), most of which depend on catalysts: "facilitating" agents also known as enzymatic cofactors. The vast majority of these catalysts are metallic or metalloid ions, present in very small quantities and essential for the body: trace elements or oligoelements.

The concept of terrain – functional pathologies occurring in certain predisposed patients – is addressed by the concept of long-term treatment with one or more terrain-modifying trace elements: this is the principle of oligotherapy.
