A brewery in Manitoba, Canada, has partnered with Canadian sleep-focused digital health company Cerebra to help evaluate their locally grown, hops-based pillow spray product, according to an article in Sleep Review.

The study involved 10 individuals who had been identified as having sleep-onset insomnia. Research subjects used the hops pillow spray for a period of one week or more and conducted a second follow-up study to measure changes in their sleep. Results suggest the Farmery Estate Brewery hops pillow spray improved the time to fall asleep for each participant, though further trials are needed to confirm safety and efficacy.

In addition to brewing beer and growing barley and hops, Farmery Estate Brewery has also been experimenting with extracting hop oil using a steam-extraction process and researching other uses and applications for hops and potential hop-oil infused products.

Chris Warwaruk, co-owner of Farmery, said in a release, “We’ve always had surplus hops from our harvest. We were looking for something else we could make from our hops, and knew there was probably some health benefits. We started testing and prototyping a line of hop-oil infused health and wellness products, such as shampoo, lotions, lip balms and skin salves—and a sleep product that would become the DreaMist Pillow Spray, a blend of our hop-oil with other aromas such as sage, frankincense, and lavender.”
