It reminded me a little about the feeling of blodroot that someone else liked at the forum, when I was trying this herb. I have been eating large amounts or Wormwood before which feels much more bitter to me, at least in taste. Still I never felt this nauseaus on Wormwood . Perhaps it has something to do with me drinking it without capsulating it? As soon as I´m a little better I will start again and do less amount each time. Did you feel the movements in your sinuses disappeared after taking this herb?
