Thanks so much for responding. I took parastroy for three weeks. My symptoms include gas issues, painful lymph nodes (not swollen) and going from frequent to infrequent bowel movements. The pain started in my stomach, then, over the course of a few months, moved to my head and extremities. It started a little less than a year ago. Without being formerly diagnosed with anything, I took a round of Cipro which helped, but never fully resolved my symptoms and a month later they were back. The course was a bit weak so maybe that's why it came back. I was then prescribed a two week course of flagyl, which I can't say helped or not. My symptoms have still persisted, but never as bad as they were six months ago. With the parastroy the pain felt so much better. I thought okay... for sure I have parasites and this stuff is actually working... but then when I stopped taking it the symptoms come back. Never as bad as they were six months ago, but they are there. I read that Wormwood has anti-inflammatory aspects to it... so maybe it made my painful lymph nodes less inflamed and when I stop taking it they become inflamed again. I don't know. What everyone's going through on here sucks and I wish no one had to go through the discomfort of sharing your body with these horrible invaders.
