earlier last year i had alot of stomache pain/cramping. although i typically do get stomache ailments every few weeks, this was really bad. in the stool i passed i had swirling worm looking things for awhile. 2-3 stools. it was scary as heck. i did a ton of instant research and read about garlic and cleansing. i got a bunch of licorice root tea with chamomille and other digestive laxative herbs. I drank this for a few days along with taking fiber and alot of water. I read that as soon as you 'see' the parasites in your stool, that means you have passed them and it is over.... im not sure, but after i saw them for a few movements and then took the herbs mentioned, the gut cramps and worms were gone. Colloidal Silver and a good multi-v with all the essential minerals couldnt hurt... good luck
