Hi Chris, I have the same problem you have. My warts show up on my nose of all the worst places to be! I've read a lot on the internet like you seem to have. I tried taking large amounts of Zinc Picolinate (is that the same as zinc sulfate?) for about 12 weeks. I tried taking large amounts of Vitamin A for several weeks. I tried taking large amounts of aloe vera, olive leaf extract, and grapefruit seed extract also. I had some treated with a laser and some frozen with liquid nitrogen. The warts that I had treated with a laser left me with crater like indentations on my skin! The ones that I had frozen healed MUCH better! I recomend to have the large warts frozen. You'll have a scab and some redness for 3 weeks or so but long term they will look much better. I've read some research that diet can influence warts. If you eat to much red meat and very little vegetables this seems to contribute to warts. I would recommend that you start eating a large amount of green vegetables on a daily basis to help. Also I personally take a bath in diluted 35% food grade hydrogen peroxide which is very good for skin problems. Please keep us updated on your progress. Thanks
