HelloPharmacist Scorecard of Hops by Herbal Terra

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: certified organic hops (Humulus lupulus) dried flower liquid extract. The extract also includes menstruum, an inactive ingredient that acts as the solvent base.

Hops flower has been used traditionally to support relaxation and sleep, though the strength of evidence for specific uses varies.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Hops product and its label doesn't state a use — see Hops's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for hops on this label is not established in the data we hold. The facts show insufficient reliable evidence to rate its use for age-related cognitive decline, sexual dysfunction, anxiety, ADHD, dyspepsia, and insomnia.

That doesn't mean it doesn't work — it means the research supporting it for these uses isn't solid enough yet to make a confident claim. If you're considering hops for a specific concern, talk it over with your doctor or pharmacist about what the current research actually shows.

The evidence, ingredient by ingredient Hops

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Hops is generally well tolerated in the short term but may cause drowsiness — so don't drive or operate machinery until you know how it affects you. Long-term safety isn't well studied, so we don't have good data on taking it for months or years.

The data advises against hops during pregnancy because there isn't enough safety information. For breastfeeding, safety is also unknown, so it's best avoided then too.

On rare occasions, people have reported allergic reactions or contact dermatitis from contact with fresh hops plant material or dust.

Side effects, ingredient by ingredient Hops

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Hops.
  • The most serious interaction on file is rated Moderate.
  • For scale: 864 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check with your doctor or pharmacist if you take sedative drugs (like sleep aids or anti-anxiety medications) — hops may add to their drowsiness effect. If you're on hormone replacement therapy or estrogen-containing medications, confirm those too.

Finally, if you take medications that your liver metabolizes via CYP3A4 or CYP1A2 enzymes (a large group including some statins, blood thinners, and immunosuppressants), verify those with your pharmacist — the clinical impact is likely minor, but it's worth confirming.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Hops may appeal to you if you're looking for herbal support for relaxation, but the evidence for specific uses isn't strong yet. If you take sedatives, hormone therapy, or other regular medications — especially those your liver breaks down — check your exact drugs with your pharmacist or doctor before starting.

Avoid it during pregnancy and breastfeeding. Talk with your own healthcare provider to see if it's right for you.

Cns Depressants

Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.
Some animal research shows that hops has sedative effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of hops might interfere with hormone replacement therapy due to competition for estrogen receptors.
In vitro research suggests that certain hops constituents can competitively bind to estrogen receptors. However, most hops extracts contain very small amounts of these constituents.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Hops extract does not seem to affect the metabolism of CYP1A2 substrates.
In vitro research suggests that flavonoid constituents of hops inhibit CYP1A2 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, does not affect levels of caffeine, a CYP1A2 probe substrate.

Likelihood Unlikely Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hops extract might alter metabolism of CYP3A4 substrates; however, this effect may not be clinically significant.
Animal research suggests that specific constituents of hops, called lupulones, can induce hepatic CYP3A4 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients with normal metabolism shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, decreases the concentration of alprazolam, a CYP3A4 probe substrate, by 7.6%. This reduction is unlikely to be clinically relevant.

Hops by Herbal Terra: Common Questions

Does Hops by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Hops has a known interaction with 863 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hops contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will hops make me drowsy?
It may. The data notes that hops is generally well tolerated short-term but can cause drowsiness. If it does affect you that way, avoid driving or operating machinery until you know how you respond.
Can I take hops while pregnant or breastfeeding?
The safety data advises against hops during pregnancy because there isn't enough information. For breastfeeding, safety is unknown, so it's best avoided then too. Talk with your doctor or pharmacist about your specific situation.
Does hops actually help with sleep or anxiety?
The facts show insufficient reliable evidence to rate hops for insomnia or anxiety. That means the current research isn't strong enough to make a confident claim either way. If you're considering it for one of these uses, discuss the evidence — or lack of it — with your doctor.
What's in this product besides the active ingredient?
The hops flower extract is suspended in menstruum, which is the liquid solvent base. There are no other added ingredients.
Is hops safe to take long-term?
Long-term safety isn't well studied in the data we hold, so we don't have solid information on taking it for months or years. If you're thinking of using it regularly, check with your doctor or pharmacist about what we do and don't know.
