There are different types of roundworms. Paragone will work good for the regular roundworms(tanish ones) and thread worms, but the Ascaris roundworm is harder to kill and usually takes L-cyestine(an amino acid) or pomegranate (also takes longer on these) to kill them. You need 3 main ingredents in the parasite cleanse, blackwalnut hull, Wormwood , and cloves, these 3 kill most worms and flukes.(not Ascaris or tapeworms)
How did you find out that you have them?
I would just take the herbs for now, it will probably take months on the herbs to get rid of all the roundworms, depending on how long you have had them and how large they have gotten(one female can lay 5,000 to 200,000 eggs each day)....heyjude
