Used forWhy
2 Stars
Insomnia
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. Chamomile, , passion flower, lemon balm, American scullcap, and catnip are commonly recommended by doctors. 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. In a double-blind trial, the combination of valerian root and hops was significantly more effective than valerian root alone for treating insomnia.

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 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

Botanical names:
Humulus lupulus

How It Works

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 to Use It

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.
