I gave my 10 year old son quercetin 500 mg with bromelein caps a few days ago and he hasn't had hives since then. I'm keeping my fingers crossed that this might be his cure or at least the best way to manage his daily hives.
My son has had hive attack daily for the past two years. They appeared suddenly out of the blue and have plagued him ever since sometimes multiple times a day. We never go anywhere without Bendadryl and Zyrtec and sometimes even those don't work so well. He also had about 20 NAET treatments with a chiropractor that gave him marginal results while he was getting them but had no long term results.
Nettle Tea, Quercetin
I have had 2 bouts of Hives after going gluten free. I believe contact with gluten is the culprit but I'm not positive. I had a very untimely breakout before Christmas and the only way I got through it was to drink tons of nettle tea and taking quercetin. Both suppress the production of histamine which causes the itching and ill side effects.
There are great supplements out there that contain both. I can't believe this hasn't been posted yet!
