Nuclear Magnetic Resonance T1 and T2 Relaxation Times of Potentized Preparations

Background: The physicochemical properties of potentized homeopathic preparations, created through serial dilution and succussion, often exceeding the Avogadro limit, have long been a subject of debate. Despite the lack of a clear scientific consensus, certain potentized preparations have demonstrated biological effects in plant assays. This study assesses basic molecular characteristics of such preparations using nuclear magnetic resonance (NMR), focusing on preparations previously shown to be bioactive in plant-based assays. NMR measures the longitudinal (T1) and transverse (T2) relaxation times of hydrogen nuclei, which are sensitive to supramolecular structures and nano-sized phenomena that might explain their biological effects. Methods: NMR T1 and T2 relaxation times were measured using a Bruker minispec mq20 at 20 MHz with inversion recovery and Carr–Purcell–Meiboom–Gill sequences, respectively. The experimental design followed rigorous protocols, including randomization, blinding, positive controls, and multiple production lots, to ensure accuracy and reproducibility. To track and correct environmental influences, such as temperature fluctuations, we systematically monitored key parameters and used NaCl and MgCl 2 control solutions to detect drifts and assess environmental impacts. This study replicates methodologies outlined by Demangeat and others, enhancing experimental rigor with systematic negative controls and environmental monitoring. Results: Data analysis is currently underway. Results will be presented at the conference and are expected to provide insights into the potential structural characteristics of biologically active homeopathic preparations. Conclusion: This research seeks to provide robust, reproducible evidence regarding the physicochemical properties of potentized homeopathic medicines. By replicating key experiments, incorporating stringent environmental controls, and using NMR spectroscopy, the study aims to uncover molecular-level phenomena that could explain the bioactivity of these preparations. The final results will contribute to the ongoing investigation into the mechanisms underlying homeopathic potentiation.
