“i can’t find any information showing this. That seems backward from how it functions. I doubt this part.”
So after looking at the Flockhart table..that many Doctors and researchers use...you might want to rethink what you are saying.
And btw, there are MANY studies that have looked quercetin as an inhibitor of P450 AND P-glycoprotein.
If anyone really wants to look at Quercetin you can look at the pharmacology at the Drug Bank.
