I had a wart show up 6 o'clock area right below my vagina on the cusp. For me, (since all women are different) it was almost on a labia fold. I was nervous but I took a small piece of a cotton ball and soaked it in ACV and gingerly placed it on the wart. I was able to 'arrange' my labia so the cotton stayed on there. Yes, it was a bit stingy. I'd check the spot after each time I peed. I'd say I'd put a new piece of cotton ball on there 2-3 times a day. After a day, it would really sting for a minute when I put the cotton on there. It took about 4 days for the wart to go away. I check the area regularly to make sure it does not start to grow again. Yes I know it is a HPV but when I was last tested for HPV I was clear.
I would not recommend this for the faint of heart, but my gyno said it wasn't a big deal... LOL, maybe not to him. I am 66 yrs old.
