Aura machines are not medical machines and do not treat, cure, or heal diseases or their symptoms. You should always ask your physician before using any type of PEMF machine. PEMF machines should not be used by anyone with a battery implanted device, such as pacemakers, cochlear implants, intrathecal pumps, etc. Magnetic fields are known to interfere with these machines. PEMF is also not recommended for clients who are currently pregnant or using chemotherapy.
