Homeopathy was born in Germany around the end of the eighteenth century through the work of Samuel Hahnemann (1755–1843). In the context of a medical era characterized by remedies such as bloodletting and the therapeutic use of odd blends of poorly defined substances, it can be understood that homeopathy had its own appeal. Yet, taking into account the Avogadro law as well as the huge dilutions of homeopathy products, their contents in term of active principles is close to zero, thus making indistinguishable the various available brands with alleged different therapeutic properties.
