What worked for me was doing Humaworm first. I would be shocked if you saw no parasites with that product. After that you have to continue the kill. Zappers help a lot, also the standard Black-Walnut , occasional Wormwood , cayenne pepper, peppermint and Colloidal Silver definitely have helped me a lot.
If you take Humaworm & don't see parasites it may be you are not quite looking right. Sometimes you gotta do an enema and get things kind of gooshy, then fish around in the bowl with some kind of long instrument.
Also, if you want to see tapeowrm segments (not the head, you need to kill that with pumpkin oil, seems to me, & it is what reproduces) just spread out over the day about 1 tsp of cayenne pepper for a week or less. You will see "white rice" in your stools. According to Hulda Clark , everyone has Tapeworms - til you get rid of them. But it is an ongoing battle apparently.
