Overview
Hops are the cone-shaped female flowers of the hop vine, most famous for flavoring beer. Beyond brewing, hops have a long history as a calming nervine and sleep aid. The bitter compounds that give beer its characteristic flavor also have sedative and estrogen-like effects. Hops pillows have been used for insomnia for centuries.
