Lufenuron is what really helped a member(Tony Orlando) get rid of his candida. I noticed more short term benefit with Lufenuron than any other RX. Lufenuron seems to work best for people that have " fungal" candida as it targets the chitin(might not be as effective for people that have candida "yeast" overgrowth?). Whether how much can reach the colon is questionable. It takes 2 months for it to be entirely effective--so sodapop might not post for a while.
