Parts Used & 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.
What Are "Star" Ratings?
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Refer to label instructions
Hops is commonly recommended by doctors as a mild sedative for those suffering from insomnia or nervous exhaustion.
Combining valerian root with other mildly sedating herbs is common both in Europe and the United States. Reference Chamomile, Reference hops, Reference passion flower, Reference lemon balm, Reference American scullcap, and Reference catnip are commonly recommended by doctors.3 These herbs can also be used alone as mild sedatives for those suffering from insomnia or nervous exhaustion. Chamomile is a particularly good choice for younger children whose insomnia may be related to gastrointestinal upset. Hops and lemon balm are approved by the German government for relieving sleep disturbances.4 In a double-blind trial, the combination of valerian root and hops was significantly more effective than valerian root alone for treating insomnia.5

Hops is one of a group of “nerve tonic” (nervine) herbs used in traditional herbal medicine for people with anxiety, with few reports of toxicity.
Traditional Use (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 Reference 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
How It Works
How It Works
Hops are high in bitter substances. The two primary bitter constituents are known as humulone and lupulone.6 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.7 Some herbal preparations for insomnia combine hops with more potent sedative herbs, such as Reference valerian. Hops also contain phytoestrogens that bind estrogen receptors in test tube studies but are thought to have only mild estrogen-like actions.8
How to Use It
The German Commission E monograph recommends a single application of 500 mg of dried herb for Reference anxiety or Reference insomnia.9 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 Reference valerian, Reference passion flower, and Reference scullcap.
Interactions with Supplements, Foods, & Other Compounds
Interactions with Medicines
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.10
