Everyone was talking about this ACV (apple cider vinegar) and I thought that I'd give it a try. I've used Aldara cream for a while and it has worked for exterior warts. But inside there is one that just won't budge, i have tried applying liquid nitrogen (with difficulty!) which hasn't done anything. However I would highly recommend this for exterior warts. They sell it here in the UK as a treatment for veruccas and warts in large pharmacies. They say not to use it for your private bits but ya know, it gets embarrassing going to the dr with that sort of stuff!
Just want to share my experience here with ACV. I have just applied it with a Q Tip and felt a burning sensation, bearable though. Left it there for approx 2 mins, maybe a bit longer. It has already shrunk massively! I would say it's a quarter of the size it was! I'm so excited that this little f*cker (excuse my language) might finally be gone and I can get on with my life. I'm going to do the same morning and night for 3 days and will comment on this post with the result. Keep your fingers crossed for me!
