Aytu BioScience posts video to YouTube describing Healight, a UV light-based technology developed at Cedars Sinai which can kill many viruses from inside the lungs. YouTube deletes said video for TOS violation.

I was just looking at some stuff on this > Ultraviolet blood irradiation (UBI) was extensively used in the 1940s and 1950s to treat many diseases including septicemia, pneumonia, tuberculosis, arthritis, asthma and even poliomyelitis. The early studies were carried out by several physicians in USA and published in the American Journal of Surgery. However with the development of antibiotics, UBI use declined and it has now been called “the cure that time forgot”. Later studies were mostly performed by Russian workers and in other Eastern countries and the modern view in Western countries is that UBI remains highly controversial. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6122858/ related - https://vitamindwiki.com/tiki-index.php?page_id=8962 They basically draw some blood, run it through a machine with the uv light, then back into the person.
