Delayed luminescence signals of Arg.met. CMf (100Mf), Canth. CMf, Bov. CMf absorbed onto sugar globuli was observed by exciting them at their known resonance frequency of 2.060 MHz. Arn. CMf also showed delayed luminescence when excited at 2.060 MHz and at 1.828 MHz. Alc. LMK (50MK) could not be excited by 2.060 MHz and showed properties of control globuli. Canth. LMK could not be excited at 2.006 MHz.The delayed luminescence signals were characterized by the coefficient B2 typical of the delayed luminescence of non-living complex systems, and by the coefficient B0 typical of living systems. Both coefficients can be considered as indicative of holistic quantum structures in homeopathic potencies.
