Hello, I began drinking nettle leaf tea and taking mg and ca last Friday as well as the foot bath with these and vit c. They seemed to help with my difficulty breathing. But then today, I had the head pressure again and am just not sure what's helping/hurting. I read that nettle contains quercetin. And I remember seeing in the past that those with COMT (I think that was the SNP) should avoid quercetin. I have COMT defective so now am not sure about the team. It also contains boron, and I think I've already depleted my sulfur b/c I've been on a low sulfur diet and probably went too far with it. So is boron from the tea a bad idea right now too? Anyone have insight into this? Thank you.
