Overview:The female flowers of the hop plant, Humulus lupulus, have long been used as a preservative and flavoring ingredient in beer. The cultivation of hops dates back to at least 860 A.D., based on written records. The therapeutic use of hops for treating anxiety, insomnia, and restlessness is first noted in Europe in the 9th century. It was introduced in England in the sixteenth century but was soon banned by King Henry VIII whose public believed it spoiled the taste of drinks, caused melancholy, and endangered the people. Young hops shoots can be eaten but it is the strobiles (oval-shaped, semi-transparent scales otherwise known as hops or hop cones) and grains that are used in medicinal teas and manufacturing beer. Hops are primarily used as a sedative and relaxant. Sleeping on a pillow filled with hops is believed to help insomnia. Hops have traditionally been used for insomnia, as a bitter to stimulate the appetite, increase the flow of digestive juices, relieve indigestion, and treat ulcers, skin abrasions, and bladder inflammation.
