"I ate just a few CC's at a staff function. Within an hour I had a red rash and itch like that from a caterpillar inside my right elbow. By the time I went to bed I was scratching myself all over the armpit and upper body. Having a shower really made it go, across my chest and up my neck on the right. The next morning at an aerobics class I had a red rash over my entire right body from the waist up to my neck, where it formed an unsightly and extremely itchy vivid red high-water mark around my neck.- by email.

"Three days later I still have lumps and itches in my right armpit and up to my face. I seem to have become hyper-sensitised to other allergens that rarely affect me, sneezing, scratching and itching. If I hadn't seen this all happen to my son I wouldn't believe that it was caused by such a small amount of an additive. And I know that it will last a week, based on his experience."
