Average Ratings


Adults (18 years and older)

For insomnia or sleep disturbances, studies have used 300 to 400 milligrams of hops extract combined with 240 to 300 milligrams of valerian extract, taken by mouth before bed. Traditionally, doses of 0.5 to 1.0 gram of dried hops extract or 0.5 to 1.0 milliliter of liquid hops extract (1:1 in 45% alcohol) have been taken up to three times daily, although using hops alone has not been well studied.

Intravenous/intramuscular dosing is not recommended.

Children (younger than 18 years)

Hops extract is traditionally considered to be one of the milder sedative herbs and to be safe for children. However, there is limited research in this area and safety has not been clearly established.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


Rash (contact dermatitis) and difficulty breathing have been reported mainly in hops harvesters. Allergy to hops pollen has also been reported. Hops allergy has been reported in a patient with previous severe allergic reactions to peanut, chestnut, and banana. Therefore people allergic to any of these agents should avoid hops.

Side Effects and Warnings

Dry cough, difficulty breathing, chronic bronchitis, and other occupational respiratory diseases have been associated with hops. Dust from hops can contain harmful bacteria. Long-term breathing problems have been reported.

Hops may cause mild central nervous system (CNS) depression (drowsiness, slowed breathing and thinking), especially when taken with drugs or herbs/supplements that also cause CNS depression. Caution is advised while driving or operating machinery.

Eating hops in large quantities may cause seizure, hyperthermia, restlessness, vomiting, stomach pain, and increased stomach acid. It is unclear what effects may occur in hormone-sensitive conditions such as cancer (breast, uterine, cervical, prostate) or endometriosis.

Hops may lower blood sugar levels in normal individuals, but may actually increase blood sugar in those with diabetes. Caution is advised in patients with diabetes or hypoglycemia and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary.

Pregnancy and Breastfeeding

Hops are not recommended during pregnancy or lactation due to possible hormonal and sedative effects. Limited research is available in these areas. Many tinctures contain high levels of alcohol and should be avoided during pregnancy.
