Any definite source? Pulling them out is usually easy.. but not always, if freezing them off is feasible and better would like to try, but this thread now has already the bad alcohol recommendation :/ so would like to make sure not just hearsay?
So I guess the recommendation remains: remove with tweezers carefully, targeting the head so as to avoid sqeezing the body and flushing toxins back into your body. Which is easier than heading to a drugstore for freezing wart removers anyway.
