Radionic machines are devices used in alternative healing practices that claim to influence energy fields and promote wellness. They are based on the principles of radionics, a controversial field that suggests that thoughts and intentions can affect physical health. Users typically adjust dials or settings on the machine to target specific issues or conditions. These machines often include a variety of components, such as crystals, dials, and electronic circuits, which are believed to help transmit healing energy. While some practitioners advocate for their effectiveness, scientific evidence supporting their claims remains limited, leading to skepticism within the broader medical community.
