What you can expect to feel when using the foot detox machine. People with edema, gout, swollen or deteriorating joints report considerable relief. Skin rashes and pimples, dark circles around eyes, swollen joints are substantially reduced and in some cases even eliminated. The foot detox machine works by introducing electromagnetic waves of a specific frequency into water, which ionizes various substances in the water. When the body's toxins are discharged, they react with the ions in the water to produce color. The color change in the water indicates the type of toxins being removed from the body. Adding salt to the water increases the conductivity of the water and enhances the detoxification effect. The machine is easy to use, simply pour water into the foot bath, add salt, and turn on the device. The detoxification process lasts for 30 minutes, and the machine will sound an alert when the cycle is complete.
