Abstract: A method and device that can deliver a time-varying electric field non-invasively inside of biological tissue and/or biological fluid such as blood and/or lymph and/or synovial fluid and/or interstitial fluid and/or other fluids in-vivo and with magnitudes that do not cause a tolerable amount of neural motor and sensory action potential generation and frequency components below the megahertz range by means of the placement of more than one electrode on the skin with or without some intermediate biological, synthetic, or natural agent or substance between the electrode and the skin and/or by induction by means of a time-varying magnetic field or both with the novel purpose of activation and/or potentiation and/or normalization and/or regulation and/or stimulation and/or signaling and/or increase and/or regulation of the alertness and/or self tuning of the immune system or any of its parts or components directly or indirectly, locally and/or globally with the purpose of pathogen load reduction and/or reduction
