Apparently we got our lines a little crossed (no pun intended) when we spoke about the Bioguard and Biophone products last time. These were two solutions mentioned to help the reader who developed an eczema-type rash around her ear when she used her mobile phone. Biophone is attached to the back of the phone and is designed to combat the effects of the radiation spectrum. Bioguard comes as a lapel pin or pendant and is designed to respond to the broader-band ELF and VLF radiation. Ecoflow in Cornwall manufactures both products.
