Rife, tested

Does a frequency kill a microbe in a dish? A blinded test, never on a person.

Open experimentNot yet tested — no completed runs as of 2026-10-22

Claim under test, in sellers of Rife frequency devices’s own words — not verified by us:

“A specific frequency, delivered by the device, destroys a specific microbe.”

How it is tested
A blinded test in a dish: yeast cultures exposed to a driven coil or to an identical sham coil, with the counting done by someone who doesn’t know which was which. Never on a person or an animal.

What is known today

A long history of claims, and of regulators

Rife devices are named after Royal Rife, who claimed in the 1930s that frequencies could destroy microbes. Sellers have repeated versions of that claim since. The US Federal Trade Commission sued one seller in 2001 over ads claiming protection against viruses and bacteria, and in 2020 warned another over COVID-19 claims for frequency programmes. We found no modern controlled study showing a Rife device kills microbes.

The full story — and which parts of it are documented — is in Royal Rife: the story vs the record.

That is why this test happens in a dish and nowhere else: if a frequency did kill a microbe, a dish is the simplest place to see it, and nobody is put at risk finding out.

What this page will never say

That a frequency treats, prevents or cures anything in a person. Even a positive result in a dish would not show that.
