In small amounts I'd imagine. I've done a ton of them and I'm still alive! I only use a pinch in a 4 oz bottle though.
Also I'm finding I have to change it up... 3 or 4 with borax (twice a week) and then 3 or 4 with acv and back & forth.
I only seem to get rid of ropes while there is albendazole in my body though... without it, enemas don't yield much.
