Figure 1: Timeline of preparation of the samples and measurements. After 34, 35, 41, and 42 days, samples of potencies and controls were either exposed to UV light (UV) for 12 h, incubated at 37°C for 24 h (incubation), exposed to an electromagnetic field (EMF) for 2 h, or incubated in an autoclave (autoclave) for 20 min, respectively, and light transmission was measured the following day (days 35, 36, 42, and 43, resp.).
