Totally agree with you about Blue Dyes. They contain a substance called cobalt that is damaging to the human body. I see a Kinesiologist (muscle tester) that is treating my parasite problem. I walked into my treatment with a blue mixed fabric jumper on, straight away she said I shouldnt wear it, especially if I was already ill. She told me to take it off so she could test my reaction to it, the difference to when I was tested with the jumper laid on me and when it wasnt was amazing. My muscles weaken significantly, needless to say I havent worn it since.
