were you asking about whether or not the 14 week candida protocol addresses parasites and heavy metal toxicity or the other program? The modern herbalist program DOES address parasites, it is antifungal and antiparasitic but doesn't address metal toxicity. If you have metal toxicity you have to investigate chelation. He recommends you get your Amalgams removed if you have them, which I haven't worried about b/c I am fortunate to not have any metal in my mouth whatsoever. If you do, I recommend you research a biological dentist skilled in the removal of mercury fillings etc... b/c it is hard to eradicate candida with that metal influence in your body. I also don't worry about heavy metal toxicity b/c I have never been a big fish eater before so while I eat a lot of salmon/tuna now, mercury has not been a concern for me before now. If you don't have a specific metal in your body, but you are just worried about metal toxicity, I would be careful. If you have candida, your immune system is probably compromised, and if you undergo too many cleanses at one time, your body may be unable to cope. A lot of different cleanses, recommend that you deal with your candida, first before your address other toxicities... But everybody is different.
