HOPS

OTHER NAME(S):

Asperge Sauvage, Common Hops, Couleuvrée, Couleuvrée Septentrionale, European Hops, Hop, Hop Strobile, Hopfenzapfen, Houblon, Humulus lupulus, Lupuli Strobulus, Lupulin, Lúpulo, Pi Jiu Hua, Salsepareille Indigène, Vigne du Nord.<br/><br/>

Overview

Overview Information

Hops are the dried, flowering part of the hop plant. They are commonly used in brewing beer and as flavoring components in foods. Hops are also used to make medicine.

Hops are commonly used orally for anxiety, sleep disorders such as the inability to sleep (insomnia) or disturbed sleep due to rotating or nighttime work hours (shift work disorder), restlessness, tension, excitability, attention deficit-hyperactivity disorder (ADHD), nervousness, irritability, and symptoms of menopause among other uses. But there is limited scientific evidence to support using hopes for any of these conditions.

How does it work?

The chemicals in hops seem to have weak effects similar to the hormone estrogen. Some chemicals in hops also seem to reduce swelling, prevent infections, and cause sleepiness.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Body odor. Early research suggests that applying a deodorant that contains hops, zinc salt, aloe leaf juice, witch hazel, chamomile, vitamin C, lemon grass, and other ingredients to the underarm can reduce body odor.
  • Insomnia. Taking hops along with other herbs and supplements may improve some aspects of sleep in people with insomnia, but research is mixed. Additionally, there is no evidence that taking hops by itself helps with insomnia. Some research suggests that taking a combination of hops extract plus valerian extract at bedtime helps some people fall asleep faster. It appears to take 28 days of treatment to see these benefits. Also, taking a combination of valerian extract and hops extract seems to improve sleep quality similarly to bromazepam (Lexotanil) when taken for only 14 days. In addition, taking a specific combination product containing valerian extract, passionflower extract, and hops extract daily at bedtime for 2 weeks seems to increase total sleep time by 2.5 hours, decrease the number of nighttime awakenings by 50%, and reduce the amount of time it takes to fall asleep by about one hour compared in patients with mild insomnia. These improvements are similar to the effects of the sedative zolpidem. However, other research suggests that taking a combination of hops, soya oil, soya lecithin, and Cannabis sativa for one month does not improve sleep quality. Other early research suggests that taking a combination of hops and valerian doesn’t improve the time it takes to fall asleep.
  • Menopausal symptoms. Early research suggests that taking a specific product containing hops extract daily does not improve menopausal symptoms such as hot flashes after 8-12 weeks of treatment.
  • Sleep disorder due to rotating or night shifts (shift work disorder). Early research suggests that drinking non-alcoholic beer containing hops at dinner for two weeks can reduce the amount of time it takes to fall asleep by about 8 minutes in nurses working rotating or night shifts. It also seems to decrease total activity during the night and anxiety. However, it doesn’t appear to increase the total amount of time slept.
  • Leg ulcers. Early research suggests that applying a cream containing bladderwrack, English ivy, horse chestnut, gotu kola, butcher’s broom, horsetail, and hops, together with compression therapy, might help decrease pain and inflammation in people with leg ulcers and poor blood circulation in the legs.
  • Tenseness.
  • Attention deficit-hyperactivity disorder (ADHD).
  • Improving appetite.
  • Indigestion.
  • Prostate cancer.
  • Breast cancer.
  • Ovarian cancer.
  • High cholesterol.
  • Intestinal cramps.
  • Tuberculosis.
  • Pain and swelling (inflammation) of the bladder.
  • Nerve pain.
  • Start the flow of breast milk.
  • Other conditions.
More evidence is needed to rate the effectiveness of hops for these uses.

Side Effects

Side Effects & Safety

Hops are considered LIKELY SAFE when consumed in amounts commonly found in foods. Hops are POSSIBLY SAFE when taken by mouth for medicinal uses, short-term.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking hops if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Depression: Hops may make depression worse. Avoid use.

Hormone sensitive cancers and conditions: Some chemicals in hops act like the hormone estrogen. People who have conditions that are sensitive to hormones should avoid hops. Some of these conditions including breast cancer and endometriosis.

Surgery: Hops might cause too much sleepiness when combined with anesthesia and other medications during and after surgical procedures. Stop taking hops at least 2 weeks before a scheduled surgery.

Interactions

Interactions?

Moderate Interaction

Be cautious with this combination

!
  • Alcohol interacts with HOPS

    Alcohol can cause sleepiness and drowsiness. Hops might also cause sleepiness and drowsiness. Taking large amounts of hops along with alcohol might cause too much sleepiness.

  • Sedative medications (CNS depressants) interacts with HOPS

    Hops might cause sleepiness and drowsiness. Medications that cause sleepiness are called sedatives. Taking hops along with sedative medications might cause too much sleepiness.<br/><br/> Some sedative medications include clonazepam (Klonopin), lorazepam (Ativan), phenobarbital (Donnatal), zolpidem (Ambien), and others.

Dosing

Dosing

The appropriate dose of hops depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for hops. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
