Herbal antibiotics didn't help at all. I did a full month on biotics research fc fidal, dysbiocide, ADP as well as allicen.
Taking prescript assist is the one thing that has helped me tremendously. Herbal abx might help you depending on what bacteria is overgrown. The benefit often told by herbals is they only kill bad bacteria and don't kill "good bacteria" such as acidophilus. I believe I have an overgrowth of d-lactate producing bacteria which most herbals don't address. I would be interested in herbal that could kill off d-lactate bacteria. All I can find is maybe cinnamon could do the job.
