The problem is that many detox agents has effects on candida and parasites as well.

ALA - I haven't seen much advertisement on the usage against candida, but ALA, being a master anti-oxidant, and going everywhere in the body, and raising glutathione must be effective against systemic candida. This is also why it is effective for patients suffering from AIDS or diabetes (they also have candida, because of lowered immunity).

DMSA - causes some form of mild neutropenia (the same thing that mercury appears to cause), makes die-off reactions more manageable, but slows down the body's ability to fight yeast & parasites.

Garlic - certainly an efficient anti-fungal, but also claimed to be a mercury chelator.

Cilantro - also an anti-fungal and anti-bacterial, but also claimed to chelate mercury

and the list goes on..
