Thanks so much for all your replies! I think I got a lot of great advice. I have been trying to help my daughter with her Lyme and Bart, really focussing on that, then the warm weather starts and the mold and allergies kick in! She also has mild asthma too, so that in combination with everything else......poor girl.
I've added the quercetin with vitamin C to her daily vitamins. She also takes Vitamin D and Magnesium Malate. She was taking the Green Vibrance capsules, but it became a bit too much for her to swallow 12 capsules a day (and she didn't like the powder mixed in with water & juice). Looks like it was a good thing for her NOT to take it anyway! She does love mushrooms, but I'll eliminate that from her diet for a couple of months.
I was ready to buy an ionizer for her room, but it doesn't sound like it does much unless I vacuum constantly (which I just might have to do). I already have an ozone machine, which I have to run in every room of my house to blast out the mold. I haven't used it yet though. I'm convinced that the mold problem in my house is severe and that needs to be addressed first.
