Quacks love light therapy for everything, whether there’s good evidence or not that it works for the condition treated. COVID-19 is no exception.
Dr. David Brownstein is a “holistic” physician who practices in Orac’s neck of the woods. Unfortunately, he just wrote a book promoting an unproven protocol involving vitamins, nebulized hydrogen peroxide and iodine, and intravenous ozone to treat COVID-19. There is no evidence that his protocol works, other than a very poor quality case series.
