This sounds more like scare tactics and advertisement than an actual cure to anything. Fear mongering is a great selling tool for pharmaceuticals. I love how they go on about unnatural substances but proceed to discuss putting something into pill form. The notion that you are allergic to your own dust, which is just your own dead skin cells, seems laughable at least. The blanket terms and ideas they use to convince people to swallow cockroach in pill form is absurd and I am curious if anyone would actually consume this. http://www.youtube.com/watch?v=62vm1Mb0T38 here is a video to something that some may find more possible and likely to work. It is called, 'spring cleaning for your nose' on you tube. However, I do agree with the idea that our diets and what we consume is becoming more and more toxic, clearly though, I do not believe the solution to this problem will be find in a pill.
