My favorite bits from the FAQ:
I have heard bad things about medical treatments in Mexico.
Most of what has been reported in the American press is accurate if not prone to hyperbole.
Will I get worse before I get better?
It is not uncommon to experience what is known as the "worm flu".
How long do the worms last?
That depends on the worm you use. In the case of hookworm you can expect them to last between three to seven years. In the case of the tapeworm it is important to kill the worm before it reaches sexual maturity.
Is it safe?
We would like to take a moment to discuss hookworm specifically. This is an organism that uses a human host and though there are animal surrogates these surrogates run the risk of attenuating the organism or transmission of zoonotic disease. Thus, we use human hosts. This means that the organism that is crawling through your skin and into your bloodstream is only a few weeks removed from developing in the ovaries of its parent organism that feeds on the blood of another human. Moreover, some companies raise their hookworm from ova to the infective L3 stage using human feces. We do not. We can mitigate the risk of hookworm carrying fecal bacteria into your bloodstream and we can use hosts that are tested for blood born pathogens but there are mechanisms of vertical transovary transmission that may exist. This type of transmission of disease has not been reported in the literature and our human reservoirs undergo routine testing to mitigate the risk of co-infection. Bottom line: do your research.
