Determined, I have noticed such things in the past - in my case with inflammation - In fact - I'll have to tell this to Idie - internal trembling would go away as well as any joint pain if I were fighting off a cold - leading me to believe these were caused by inflammatory cytokines which in the event of an actual infection went off to fight THAT instead of me. So...I would guess that chemicals cause inflammatory cytokines for you and I'll bet strategies against those might do the trick. But what are such strategies? Well one is high dose omega-3 (like 7-9g/day) as these use up the enzymes required to produce inflammatory cytokines. When I had a horrible new allergy develop last winter I found 20 Spirulina pills woul do the same thing. Neither is fun as it's so much. There are herbs that are supposed to help with inflammation, thus must target those cytokines, like curcumin. However if you are on meds, and you are, these strategies can be dangerous. Omega-3 thins the blood. I don't know what spirulina does but you can bet there are a lot of constituents in at, any one of which might interact with your meds. Curcumin interacts with 50% of the medicines on the market via CYP3A4...it will PREVENT you from eliminating any medication which is supposed to be cleared via CYP3A4 (50% of the drugs on the market) and this will cause their levels to rise to where they could be toxic. So many herbs do just this sort of thing that I would never take any herbs if I were on drugs. As to blood if your drugs thin your blood or affect clotting this is also something you need to do only under a doctor;s care. For someone NOT on drugs, the above are things I might look into. Rydra Sorry, the Yasko report does not contain rs numbers. If I were to research it I would never remember which topic this was under to report back. You could probably look onlin eas well as me for "CBS gene rs" or some such. But it will not necessarily help you find a solution. I mean a lot of CBSers are still sick.
