my DS2 had threadworms for near on 6 months last year and they refused to go with every single treatment available,and having microbiology dont to try to find a way of combatting them, they only seemed to go when he got sick. now they are back and after one night up with him crying most of the night im on the hunt for something to get rid of them! an old lady told me to give him a savoy cabbage heart raw and to make sure he uses the potty as the main culprate will expose itself from the gut. is this worth a try? no one else in the house has them. he is just 6....
