Nosodes are ultra-dilute preparations made from diseased tissues or organisms used in homeopathy since 1830, more frequently used since 1880. Carcinosin is a commonly used nosode prepared over 100 years ago from cancer tissues in the last part of the nineteenth century, of which the exact scientific information on the histopathological characterization of the source material is not available. The current therapeutic indications of Carcinosin have been largely empirical and clinically derived. In such a scenario, understanding the paramount importance of the Cancer nosode, it’s revamping in the light of current scientific knowledge has been identified by the author. Specific cancerous tissue samples were sourced for nosode preparation. Identified pieces of tissue were histopathologically diagnosed, thoroughly washed, quantified and triturated with powder of Saccharum lactis to prepare decimal potencies, as per standard method suggested in the Homoeopathy Pharmacopoeia of India. Centesimal potencies were prepared using electromechanical potentizer, documenting the force parameters. The Cancer nosodes from specific cancer tissues were prepared in a systematic manner, which could be used for research as well as in clinical practice. The author has attempted scientific preparation of new Cancer nosodes making them available to the profession. On similar lines, more of cancer tissues could be explored for making other nosodes. (AU)
