Pumpkin seeds are limited in the types of parasites they address, and fennel has no antiparasitic properties that I am aware of. Do a Black-Walnut -wormwood-clove parastie cleanse...Clarkia, ParaGone of Old Amish Dewormer are some to try. The Master-Cleanse is also a kidney cleanse and should be sufficient...unless you have a history of kidney problems, in which case you may want to use an herbal combination kidney cleanse.
