Viruses tend to like biofilms (candida colonies) as hideyholes, have you found any bowel cleanses that help detatch the hyphal attachment points of biofilmic colonies in the gut?
That may lower your HPV count signifigantly- I have been studying the subject.
Digestive enzymes speed the healing process, as mentioned in the earlier reply thread by another forum member here, but they tend to break down biofilms and increase the load without activated charcoal to hand.
Vitamin D speeds the apoptosis (cell death) of infected cells which can harbour the virus inside your own tissues, which can account for the rise in HPV count. There is no fault in using vitamin D, because it aids in the production of vital new tissues as well.
I am familiar with the Marshall protocol- and yes, extra silica from horsetail or diatomaceous earth really helps! It gives a heck of a dieoff though, so extra vitamin C and liver helpers like dandylion root and milk thistle (holy thistle, etc) are good to compliment that.
Write back if you'd like me to write up more about detatching biofilms. (mucoiud plaque, fodmaps, mucicin, same game, different name).
