Good thought. Might have been. I don't know, probably will never know what it was.
After I finish the run of parasite-killing herbs I was planning on doing a gallbladder flush, but I feel SO much better, I am wondering if I should bother. My gallbladder symptoms are gone. Didn't disappear in immediate conjunction with passing the red ball, but they are definitely gone. Well, yeah, I will do a flush. I want to see what comes out.
I do know I passed lots of small red fragments in my stool on a couple days since then.
I was thinking broken-up liver flukes, but might have been small stones. I'm just not that into seiving my poop... I still have the ewww yuck response.
