A few that I came across while reading on something or other:
Anise, Barberry, Berberine,
Black-Walnut , Clove oil, Curled mint, Goldthread, Goldenseal, Grape fruit seed extract, Propolis, Oregano oil, Oregon grape,
Wormwood
BTW Be very careful with some of these herbs, check them out thoroughly before using any of them!
