In this provocative episode of ReversABLE, Josh Dech sits down with physician Dr. Tom Cowan for a wide-ranging conversation about disease, scientific reasoning, the heart, viruses, bacteria, environmental exposures, hormones, and the assumptions underlying conventional medicine. Cowan describes his unusual path into medicine, including 37 years in family practice, and explains the philosophy that drives much of his work: rather than immediately trying to determine what is true, first investigate whether the original claim has actually been demonstrated. That framework takes the conversation into controversial territory. Cowan challenges conventional explanations surrounding viruses and germ theory, using examples involving polio, measles, SARS-CoV-2, bacteria, antibodies, and laboratory procedures. He argues that some commonly accepted demonstrations of causation do not establish what they are claimed to establish. These are among the most contentious claims in the episode and are presented as Cowan's perspective rather than settled medical consensus. The discussion then shifts into physiology, where Cowan challenges the conventional description of the heart as a pressure-propulsion pump. He presents his theory of the heart as part of a vortex-based circulatory system and connects that concept to blood flow, pressure differentials, tissue-level physiology, and electrically charged water. Josh and Tom also explore mold, parasites, bacteria, environmental toxins, EMFs, inflammation, and the question of whether the presence of a microorganism necessarily establishes it as the root cause of illness. One of the most compelling themes throughout the conversation is critical thinking: separating observation from interpretation, correlation from causation, and established evidence from assumptions. For anyone interested in gut health, chronic illness, inflammation, the microbiome, immune system, root-cause health, functional medicine, or simply questioning how medical conclusions are reached, this episode offers a conversation designed to challenge your assumptions—and encourage you to investigate the claims for yourself.
