gruit was and is a combination of herbs, commonly including sweet gale ("myrica gale"), mugwort ("artemisia vulgaris"), yarrow ("achillea millefolium"), ground ivy ("glechoma hederacea"), horehound ("marrubium vulgare"), and calluna heather ("calluna vulgaris"). gruit varied somewhat, each gruit producer including different herbs to produce unique flavors and effects. other adjunct herbs include juniper berries, ginger, caraway seed, aniseed, nutmeg, cinnamon, mint and occasionally hops in variable proportions (although gruit today is often sought out for lacking hops).
