Another factor behind switching from gruit to hops could have been concerns about public health. With stimulating, psychotropic and ultimately poisonous plants such as henbane (Hyoscyamus niger) or even deadly nightshade (Atropa belladona) being used rather routinely in beer brewing, local lords tended to want to edict a workable rule-of-thumb for the spicing of beer, preferably using a single, non-toxic herb which would be easier to monitor than a complex mix. Hops grow freely in most of continental Europe and its innocuousness being relatively clear, it was ideally suited to the task. Hops also have a number of advantages as far as spoil prevention: beer made with hops allegedly last longer than that made with gruit. This no doubt had a large impact on the choice to switch over, although it must be pointed out that other plants commonly used in gruit mixes, for example sage, rosemary or bog myrtle, also have antiseptic properties likely to extend the shelf life of beer.
