Actually I have started UT which is why I am asking these questions. I had tried to start it once before 2 years ago when I noticed my parasites but because of this concern I didn't continue. I started again because with the naked eye I haven't noticed the same parasitic indications but will scope some samples soon. I can of course always take antihelmintic herbs along with doing UT. But others might also be concerned as I am about the possability of recycling the buggers. I'll let you know if I see any eggs or worms as I've been going the UT for about a week. I did try the do the exterior application of aged urined yesterday and just about hurled. Assuming this was supposed to be unrefrigerated collections how can anybody stand to apply aged urine anywhere when just opening the bottles is enough to vomit? Is it known just why aged urine smells so much or is ther a way to recue the odor?
