In April-2020, this report concludes, the United States Federal Trade Commission began sending out “warning letters” to Rife Machine makers that had discovered and programmed into their devices the resonant frequency for the Covid virus, and stated: “For COVID-19, no such study is currently known to exist for the product identified above...Thus, any coronavirus-related prevention or treatment claims regarding such product are not supported by competent and reliable scientific evidence”—US government “warning letters” that were followed by The Energy and Resources Institute (TERI) in India announcing it had found a way to cure the COVID-19 by using an extraordinary sound therapy using electro-frequency vibration, exactly like the Rife Machine does—and is astonishing research joined with that conducted by Dr. Minghui Yao and Dr. Hongbo Wang at the School of Artificial Intelligence, Tiangong University in Tianjin-China, who in their critical to the world scientific paper being kept hidden from the American people titled “A Potential Treatment For COVID-19 Based On Modal Characteristics And Dynamic Responses Analysis Of 2019-nCoV”, revealed: “The 2019-nCoV is ravaging the world, taking lots of lives, and it is emergent to find a solution to deal with this novel pneumonia…This paper provides a potential treatment for COVID-19 utilizing resonance to destroy the infection ability of 2019-nCoV”.

Note: Thanks to Jerry Tennant, MD, and his personal research into an original Rife machine that was discovered behind a false wall, (As documented in his HEALING IS VOLTAGE series, particularly the CANCER/POLARITY book) we know why the original Rife Machines worked (almost too well - all pathogens on several floors were killed by the machine) and why current versions called "Rife Machines" are not the same as the original. However, there is value to electrical healing, and these two countries' research is being withheld from Americans.
