From scientific point of view, role of sarcodes or animal products in homeopathy arise from the fact that they contain diverse types of biological ligands that play important roles in the normal biological processes happening in living body. Biological ligands include substrates, inhibitors, activators, signaling lipids, and neurotransmitters. Various hormones, cytokines, immunoglobulins, neuclic acids, neurochemicals, metabolic byproducts etc also work as biological ligands.
In normal biochemistry, each biological ligand can bind to a particular biological target of protein structure due to their conformational affinity, and work as a molecular key in effecting some molecular transformations. That is the way normal biological processes work.
During disease proceses, some pathogenic molecules compete with biological ligands having conformational similarity and bind to the biological targets, causing their inhibition that lead to disruption of normal biological processes.
When sarcodes are potentized above 12c, the biological ligand molecules contained in them undergo molecular imprinting, and as such, potentized sarcodes will contain only molecular imprints of constituent biological ligands.
When used as medicines, these molecular imprints can bind to the pathogenic molecules having conformational affinity and deactivate them.
Deep understanding of biochemistry and molecular pathology is essential to identify the biomolecular targets as well as molecular processes involved disease processes, so that most appropriate biological ligands or sarcodes could be selected and applied in molecular imprinted forms as therapeutic agents.
