Can I use fenben for my children? My 4 and 2 year old have several parasites. We live in mold. Iím so stressed about how to treat them as they cannot tolerate herbs due to MCAS. They are chronically starving all the time, have major stomach issues, etc. A biofeedback machine shows they have schistosomiasis, hookworm and Giardia. I donít want to creat resistance but also donít want to hurt them with harsh medications. I donít know what to do! Any advice appreciated.
