Colloidal silver is an excellent choice and should be very effective against HPV. Colloidal silver is nature's antibiotic and kills single cell pathogens, even those that have become resistant to antibiotics. However, for something such as HPV, you want to make sure that you are ingesting true colloidal silver and not ionic silver or something of a lesser quality. Utopia Silver which is also a Curezone sponsor, has a high quality product. Right now they have a 25% sale. However, in the future, members of this forum get a 15% discount on items not on sale by inserting code LR001.
In addition, Oleander extract is over 90% effective against all types of cancer and since you mentioned that there are cell changes, I highy recommend that you incorporate Oleander into your daily regimen. This should take care of those abnormal cells and continual use of Oleander should prevent the onset of cancer. Myself, I take Oleander as a preventative. You can either purchase it at http://www.sutherlandiaopc.com or you can make the soup yourself. Below are the links:
However, if you should choose to make the soup, please keep in mind that you must follow the directions precisely and you must also insure that the plant you use has not been sprayed with commercial pesticides, even if you get it from an organic nursery. Not all organic nurseries are "organic."
Let me also include Tony's anti-cancer protocol which will guide you in a complete lifestyle change, together with giving you the supplements that will boost your immune system.
