CS>Basic CS Question -- Anyone?

[Marmar845]

The following comment was made on one of my  lists, and I wanted to bring it 
up here for input.
 
>>Just speculating --  CS kills the offspring of internal  parasites at the 
single-cell stage, so they can never successfully  reproduce.<<
 
The comment pertained to effective worming for  horses.  I'm wondering about 
the assumption that CS would kill *parasites*  at the single-cell stage.  Any 
thoughts?    MA
