I dose low level of ALB and FenBen for Ascaris and Strongyloides.
I would be tempted to try FenBen and low dose MBZ for Toxo.
The use of Papain every night has all but eliminated the need for me to take IVM, I have no birthing signs, or acid, or gerd, or wormballs from the lungs. The 3 and 10 day reproduction cycles have stopped. I do have purple balls in my ankle veins, (strongyloides) that virtually disappear when dosing FenBen. I am certain that once Strongyloides are eliminated, my problems will be over.
I do the naturals nematodea formula with FenBen and ALB, trend line is good.
There may be circumstances where or one could consider taking low dose mebendazole, I have corresponded with several that claim it eventually knocked out their infection.
I personally believe the devil is in the details, and that getting to the stages with naturals and pharmas is the most direct, and fastest approach.
Identifying the antiparasitic of choice, with co factors, and hitting it hard, eventually gets results. This is like watching grass grow in Kansas. Mind Numbing.
