The original use of Lufenuron was to stop the development of fleas on dogs and cats. It worked the same way there, by inhibiting the formation of chitin, which is what the exoskeleton of hard bodied insects is made of. It is the same stuff that the mouth parts of soft bodied insects are made of, so Lufenuron affects the development and production of nearly every insect that can plague man and beast.

It is starting to be recognized that many people who have Leaky Gut and therefore Systemic Candida, also have parasites.
