Ionic foot detoxification does not work, because the skin, a natural barrier, prevents large amounts of toxic or other chemicals from passing through it, reports the Los Angeles Times. There is no scientific support for the claim that adding an electron to hydrogen atoms clears free radicals from the body.
Scientists have concluded that ionic foot baths are ineffective as promoted because they defy the laws of chemistry and physics. If an ionic detox actually produced negative hydrogen ions, the ions would burn a person's feet, explains the Los Angeles Times. The foot baths use low voltages that cannot break water molecules apart, and if they did, the resulting hydrogen ions would have a positive rather than a negative charge.
