Re: another super bug from a lab perhaps?
I would dip a sponge in some diluted Iodine, insert and leave overnight, do the same with goldenseal tincture. I would also take them both internally, in addition to the other recipe. I make a great big batch of tea, keep it in the refrigerator, and drink a big swallow or two several times per day. It tastes horrible, but it works.
If that doesn't work, I would google anti-biotic herbs, make a list, buy as many as I could, take them both internally and do the dip the sponge trick. Be very careful about infusions, as tinctures and concoctions will burn the delicate vaginal tissues if you make them too strong.
Start with a small amount and slowly increase by a couple of drops each day until it starts to burn just a tiny little bit and then decrease a drop or two. That is your dose.
