Haven't tried Humaworm, but I've tried a few others, Black-Walnut , Paracleanse(?), the HC Zapper. None of these had any noticeable effect, leading me to the conclusion that parasites were not the problem.
My view of the particular form of candida I have is that it's a simple fungal infection. An incredibly tough and resilient one. It responds to everything I've thrown at it over the years by initially decreasing and then, after a week or two, adapting and resuming it's course.
But perhaps I'll give the Humaworm protocol a try.
