I was diagnosed with labial cysts two months ago. My doctor drained the largest cyst and put me on antibiotics but as soon as I was off them, it popped back up again. I went back and he put me on on antibiotics yet again but still no cure. I assumed you could put apple cider vinegar directly on this cyst. I put it on twice by soaking Cottonwool in and organic ACV and leaving it on for 10 minutes. It stung like crazy. The cyst is no longer raised but flat and red raw and weeping. I can barely walk. And all I would say that apple cider vinegar works but I guess you need to dilute it, who knew?!
