HelloPharmacist Scorecard of Wild Hops by Hawaii Pharm
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
This product contains one active ingredient: Wild Hops extract, a liquid supplement made from the hops plant. The extract is mixed with vegetable palm glycerin and alcohol as inactive ingredients.
Does it work?
Couldn't assess
The evidence for hops extract in the conditions it's marketed for — cognitive decline with aging, sexual dysfunction, anxiety, ADHD, indigestion, and insomnia — is not established in the data we hold. Every condition listed carries an "insufficient reliable evidence" rating, meaning we don't have enough solid research to say whether it works.
How safe is it?
Well-documented data
Hops is generally well tolerated in the short term, though it may cause drowsiness — something to keep in mind if you're driving or operating equipment. Long-term safety hasn't been well studied, so we don't know what happens with extended use.
The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know it's safe. Workers who harvest hops have reported menstrual disturbances, and occupational exposure to hops dust has been linked to respiratory symptoms like cough and chronic bronchitis — though that's from the dust itself, not oral supplements.
A small number of postmenopausal women taking supplements combining hops and soy experienced abnormal bleeding, though it's unclear whether hops, soy, or the combination was responsible.
Meds to double-check
Moderate interaction found
Before taking Wild Hops, double-check with your pharmacist if you take any sedative or sleep medications, estrogens or hormone replacement therapy, or drugs metabolized by the liver enzymes CYP1A2 or CYP3A4 — a large group that includes some heart and cholesterol medications. No interactions are documented for the ingredients we could check beyond those listed above.
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.
Wild Hops might appeal to someone looking for a natural sleep aid or anxiety support, but the evidence for those uses isn't solid yet. If you take sedative drugs, estrogen therapy, or medications your liver processes through CYP1A2 or CYP3A4, you should check your specific medications with your pharmacist before adding this.
Avoid it in pregnancy and while breastfeeding. Talk to us before you start.

Wild Hops by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Wild Hops by Hawaii Pharm contains a single active ingredient — hops extract — that does interact with some medications, so you'll want to check your list before starting.
Read the full breakdown — every affected drug type, severity by severity
The most serious concern is with CNS depressants (sedative drugs like benzodiazepines, sleep aids, and opioids). Hops has sedative properties of its own, and taking it alongside these medications could cause extra drowsiness — a Moderate severity interaction.
Similarly, if you take estrogens or hormone replacement therapy, large amounts of hops might theoretically interfere because the herb's constituents can compete for the same receptors; however, most commercial hops extracts contain very small amounts of these active compounds, so the real-world risk is less clear.
Hops also has Minor interactions with two groups of drugs that your liver metabolizes through specific enzyme systems: CYP1A2 substrates and CYP3A4 substrates. Animal studies suggest hops could shift how your body processes these medications, but a pharmacokinetic study in humans didn't find a clinically meaningful effect, so the actual impact appears to be small.
Use the medication checker on this page to look up your exact drugs. Altogether, these interactions span 853 individual medications.

For each ingredient in Wild Hops with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Wild Hops extract
Cns Depressants
Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.
Some animal research shows that hops has sedative effects.
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.
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.
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.
