You're welcome.

My allergic type symptoms seem to have minimized with the introduction, but it's too soon to tell. I've also been breaking my diet now and then, so I can't tell. Now I'm back on it and has more of a baseline. The studies linked to in the article, this one in particular, note that quercetin blocks more than just histamine, which is why it's so promising. Apparently unlike any other mast cell stabilizer, it also blocks the inflammation. Anyway, worth a try, since it has all sorts of other benefits. I hope it works for you. I just skipped the histamine step, keeping to the natural root. I take 500 mg of quercetin with breakfast. With so little work on the supplement and this issue, it's difficult to know dosage and such things. I may up it to up to 3 500 mg doses at some point, but not now.

I'm seeing a specialist in a week's time, got lucky with an early appointment, otherwise it wouldn't have been till August. I don't know if I'm going to run the tests, since they're not particularly the best and so often result in false negatives. My situation/symptoms, etc. are always changing. Plus, I'd have to pay out of pocket, just over $1100. I may just take the quercetin approach and see what happens, because if I do have it, all they will do is try to use a chemical pharma cocktail to stabilize the mast cells. The one thing I think about is whether I have mast cell proliferation, but there I don't want to do a bone marrow biopsy, since it's invasive and has risks.

Well, I hope your testing and quercetin use are useful. Such a journey indeed! Keep me posted and I'll do the same. In the meantime, good luck!
