Botanical nameHumulus lupulus
Parts used and where grown
The hops plant, Humulus lupulus, is a climbing plant native to Europe, Asia, and North America. Hops are the cone-like, fruiting bodies (strobiles) of the plant and are typically harvested from cultivated female plants. Hops are most commonly used as a flavoring agent in beer.
Hops have been used in connection with the following conditions (refer to the individual health concern for complete information):
Science Ratings - Health Concerns
* - Anxiety
* - Insomnia
* - Poor appetite
*** - Reliable and relatively consistent scientific data showing a substantial health benefit.

*** - Reliable and relatively consistent scientific data showing a substantial health benefit.
** - Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
* - For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.
Historical or traditional use (may or may not be supported by scientific studies)
Soothing the stomach and promoting healthy digestion have been the strongest historical use of this herb. Hops tea was also recommended by herbalists as a mild sedative and remedy for insomnia, particularly for those with insomnia resulting from an upset stomach.1 A pillow filled with hops was sometimes used to encourage sleep. Traditionally, hops were also thought by herbalists to have a diuretic effect and to treat sexual neuroses. A poultice of hops was used topically to treat sores and skin injuries and to relieve muscle spasms and nerve pain.2
Active constituents
Hops are high in bitter substances. The two primary bitter constituents are known as humulone and lupulone.3 These are thought to be responsible for the appetite-stimulating properties of hops. Hops also contain about 1–3% volatile oils. Hops have been shown to have mild sedative properties, although the mechanism is unclear.4 Some herbal preparations for insomnia combine hops with more potent sedative herbs, such as valerian. Hops also contain phytoestrogens that bind estrogen receptors in test tube studies but are thought to have only mild estrogen-like actions.5
How much is usually taken?
The German Commission E monograph recommends a single application of 500 mg of dried herb for anxiety or insomnia.6 The dried fruits can be made into a tea by pouring 1 cup (250 ml) of boiling water over 1–2 teaspoons (5–10 grams) of the fruit. Steep for ten to fifteen minutes before drinking. Tinctures, 1/4–1/2 teaspoon (1–2 ml) two or three times per day, can also be used. As mentioned above, many herbal preparations use hops in combination with herbal sedatives, including valerian, passion flower, and scullcap.
Are there any side effects or interactions?
Use of hops is generally safe. However, some people have been reported to experience an allergic skin rash after handling the dried flowers. This is most likely due to a pollen sensitivity.7
At the time of writing, there were no well-known drug interactions with hops.
