So yeah its a complicated issue. Unfortunately there are crappy rife machines out there, and also some use frequencies that are simply ineffective.
I have owned several rife machines and always recommend the spooky plasma whole heartedly. GREAT machine, its the real deal. https://www.spooky2-mall.com/product-category/kits/spooky2-central-plasma-kits/
the plasma energy permeates anything, bone, blood, tissue etc. Much better than the hand held units that use electrical charges.
I also recommend the DNA frequencies which are calculated using the published genome info. The inventor has figured out how to calculate the kill frequency that literally dismantles the DNA of the pathogen. https://www.dnafrequencies.com/
Spooky also has its own very large database of frequencies you can use, for free. They also have a forum where you can discuss and ask questions and any problems you have with your machine someone can help you. https://spooky2.com/forums/index.php?sid=4c02e5b671c639e9db4e2c16a3a99e8a
I had a crazy intense painful rash on my back while back. Didn't know what it was, finally got diagnosed with shingles. Got the shingles DNA freqs (Human herpesvirus 3), cranked up the rife plasma machine, and in just 2 days the pain went from 10/10 to about
Had some kidney problems. Tried different freqs for that, finally discovered that the Hantavirus could infect the kidneys. Got the DNA freqs it, treated with the rife, and kidneys felt and worked much much better.
My main problem right now is mercury however, and the rife cannot help with that. Only chelation helps and thats a slow process. The rife treatments do however, free up mercury that is hiding in Lyme biofilms.
I am a big believer in rife technology and also totally understand anyone who is skeptical. Its expensive and there are many who don't use it correctly and then go online and proclaim it doesn't work and doesn't help anyone. You have to use it correctly. You have to use the right frequencies and you have to get a quality machine.
