How does radionics work in homeopathy?

Radionics in homeopathy is based on the belief that diseases can be diagnosed and treated through the use of subtle energies or vibrations emitted by the body. Practitioners use instruments to detect these energies and identify imbalances, often employing "witnesses" such as hair or blood samples. Remedies are then formulated to restore balance, often involving potentized substances that are thought to resonate with the patient's energy field. Critics argue that the scientific basis for radionics lacks empirical support, viewing it as a pseudoscience.
