I took teasel root for about a month from 1 to 3 drops. I only have a clinical diagnosis of lyme so can't say for sure if it is attacking that or not, but can say that it does the same to me that samento did when I took it. It leaves me exhausted the next day. I took it while I had a cold so I really didn't care about the side effects as I was feeling crappy anyway. No way I can take it now that I am working again.
ON the plus side, my stomach got better from ibs after a month of taking it. My joints felt really good. The pain in a bad knee went away. So felt better after stopping the teasel than I did before I started it. Had some shortness of breath problems, but not sure if from the teasel or the cold. I ended up getting another cold a few weeks after my first cold...lucky me, and the progress I had made has gone away.
