This is a tough question.
I haven't killed many large worms yet so I don't know the answer.
ARe you taking broad spectrum meds? Prazi, albendazole, any iver?
ASk ICU...she knows a lot and so does..I will have to find her number and tell u later 140..something like that
Prazi and albendazole will kill many different species..just takes time
Are you taking MSM, zinc and c and also iodine, digestive enzymes?
