Just one question. Please can you explain to me how these 2 drugs work together, as piperazine is an antagonist with pyrantel? Or in this case it does not matter? And the stone breaker herb you have mentioned in your email, does that help you so far with the nausea? I know that fresh ginger can also help with that but have not yet tried it after pyrantel. Great research by the way. I guess engineers should replace parasitologists..
