I work for Mountain Town Brewery in Michigan, one of our staple beers is the Sacred Gruit, probably my favorite beer we brew and I am a Hophead if that says anything. Obviously I can't talk about any specifics but here is the description with the herbs we use from our website to give you an insight
"What is Gruit you might ask? Gruit is a blend of herbs that brewers added to their beer in the renaissance times if not before. Herbs are an essential ingredient in beer, both as a preservative and to counterbalance the bitterness and flavoring. Herbs were the only thing used prior to the extensive use of hops. Sacred Gruit ale is a pale ale brewed with primary combination of three mild to moderate herbs yarrow, sweet gale (myrtle) and marsh rosemary (wild rosemary)."
It's an awesome style of beer an would encourage anyone to brew it
Also would like to add we don't pasteurize or filter and we bottle this, don't believe we have ever had a problem with infections from the herbs or lack of hops.
