Hops (Humulus lupulus)

Traditional indications

Hops are anti-microbial, anti-spasmodic, astringent, hypnotic and sedative. Hops has a marked relaxing effect upon the central nervous system. It is used extensively for the treatment of insomnia. It will ease tension and anxiety, and may be used where this tension leads to restlessness, headache and possibly indigestion. As an astringent with these relaxing properties it can be used in conditions such as mucous colitis. It should, however, be used in caution in marked depression. (1)

Pharmacognosy

Hops, an essential beer ingredient, are a source of prenylflavonoids, including 8-prenylnaringenin (8-PN), one of the most potent phytoestrogens. (2) Hope is known to be a potent phytooestrogen (3) thereby protecting against oestrogen dependent cancers. (4)

A mixture of valerian and hops extract improves sleep-related behaviours, including sleeping time, by modulating GABAergic/serotonergic signaling. (5)
