Oddly enough Quercetin is also a detoxer. I've lived in a house that unknown to us had massive amounts of mold in it. We've used a few detoxers & last winter we were using quercetin for immune boost and started feeling much better. Fast forward to spring, I listened to a doctors lecture about mold & people using Quercetin to detox. So its good for multiple things. No one in my family herxed from it either.
