Kleen Green is an enzyme that will get all kinds of bugs on the outside.
As far as I can see, drugs don't work for parasitic infections. You can't stay on them long enough for it to work. They'll just come back. they'll come back if you don't use a good herbal long enough and do some internal cleansing. Herbs with Wormwood , cloves and green hull of male walnut buds work over time. That entails dong a good Colon Cleanse over time as well as flushing out the liver. Once that's accomplished, I wouldn't go off a maintenance dewormer of every three days for the rest of my life. I use whole food supplements to get my immune system up there.
You could ask a master herbalist about the kids. email@example.com He makes some good herbals and is knowledgeable. He also has sprays that work on the outside of the body. All his stuff worked very well for me.
