evidence: Hulda Clark’s "zapper" device is based on pseudoscience; doesn’t kill parasites or cure diseases [...] In the Facebook video, Clark explained how to use the "zapper", an electric device she developed herself that supposedly cures all diseases by clearing parasites from the body. Iterations of Clark’s claims are also common on TikTok, where they accumulate hundreds of thousands of views. [...] Then came the "zapper", a device consisting of two copper handles connected to a battery that pulses mild electric currents (nine volts) through the body at a specific frequency (bioresonance). This device is based on the idea that each living organism, including parasites, produces a unique frequency. The "zapper" is supposed to specifically counter the frequency of parasites, killing them without harming human tissues.
