Hops

Hops are the female flowers (cones) of Humulus lupulus, a climbing plant most commonly grown in Europe. Hops have been used for hundreds of years as herbal medicine to treat sleep problems as well as anxiety, irritability, excitability, and restlessness. Research indicates that the sedative effects of hops may come from its ability to lower body temperature. Lowering body temperature helps to bring about drowsiness and is an important part of the body’s sleep process.
