HelloPharmacist Scorecard of Sleep by Eclectic Herb

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Sleep by Eclectic Herb contains 5 active herbal ingredients in a liquid form. The product includes a proprietary blend — meaning the exact amounts of each ingredient aren't disclosed separately — along with valerian, anise, hops, passionflower, and chamomile.

The inactive ingredients are glycerin and filtered water. Each of these herbs has traditional uses for sleep and relaxation.

Valerian root is the most studied for sleep support. The product also contains two inert ingredients (glycerin and water) that serve as the liquid base and preservative.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: promotes rest and sleep for children.
  • We looked for evidence on: Insomnia, Anxiety, Stress, Adjustment disorders, Sleep quality, Sleep initiation — and 1 related terms.
  • The strongest evidence on file: Valerian is rated "Possibly Effective" for Insomnia (Natural Medicines).
  • Also on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety, Insomnia.
  • Also on file: Hops is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Insomnia.

The evidence for this blend is mixed. Valerian is rated possibly effective for insomnia based on available research.

Passionflower is also rated possibly effective for insomnia and for anxiety before medical procedures. However, for the other ingredients and conditions — including anise, hops, and chamomile for sleep — the evidence we hold isn't strong enough to establish effectiveness.

That doesn't mean they don't work; it means the data hasn't yet proven it clearly enough for us to rate them.

The evidence, ingredient by ingredient Valerian Anise Hops Passion Flower German Chamomile

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Valerian is generally well tolerated short-term, but long-term safety isn't well studied. Common side effects include dizziness, drowsiness, mental slowness, headache, and vivid dreams.

If you've taken valerian for a while and stop suddenly, you may experience withdrawal symptoms like anxiety, irritability, or insomnia — taper the dose slowly instead. Rare cases of liver problems have been reported with multi-ingredient products containing valerian.

Anise is generally safe as a food or tea but needs more caution when used medicinally. Hops and passionflower can cause drowsiness short-term; long-term safety isn't well studied.

Chamomile is generally well tolerated but can trigger allergic reactions in people sensitive to ragweed. Passionflower, hops, and chamomile are all best avoided during pregnancy due to insufficient safety data.

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?
  • 5 of the 5 matched ingredients can interact with medications — Anise, Hops, Valerian, Passion Flower, German Chamomile.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,072 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 pharmacist if you use any central nervous system depressants (sleeping pills, sedatives, anxiety medications, or painkillers with sedative properties) — valerian, hops, passionflower, and chamomile can all add to their drowsy effects. Also double-check if you take blood thinners like warfarin, oral contraceptives, estrogen therapy, diabetes medications, or antidepressants — multiple ingredients in this blend may interact with these drug types.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're looking for help with insomnia and don't take sedating medications, blood thinners, birth control, or psychiatric drugs, this might be worth discussing with your pharmacist. Anyone on medications — especially sleeping pills, anxiety drugs, blood thinners, diabetes medications, or hormonal contraceptives — should check their specific medications with the tool on this page before starting.

Valerian6 drug types · 902 drugs

Alcohol (Ethanol)

Valerian can have additive sedative effects when used concomitantly with alcohol.
Valerian has sedative effects. Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba. However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone.

Likelihood Possible Evidence B
Alprazolam (Xanax)

Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Valerian has sedative effects. Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4). Despite being statistically significant, this increase is not likely to be clinically significant.

Likelihood Possible Evidence B
Cns Depressants

Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.

Likelihood Possible Evidence D
Glucuronidated Drugs

Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme. In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate.

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

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme. In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4. However, this mild inhibition is unlikely to be clinically relevant.

Hops4 drug types · 863 drugs

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 full monograph & interactions

Passionflower3 drug types · 836 drugs

Cns Depressants

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.

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

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition. OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

anise11 drug types · 245 drugs

Antidiabetes Drugs

Theoretically, anise seed might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A small clinical study shows that anise seed powder decreases fasting blood glucose levels by 36% when compared to baseline.

Likelihood Possible Evidence B
Caffeine

Theoretically, anise oil might decrease the efficacy of caffeine.
Animal research shows that taking anise oil with caffeine decreases the bioavailability of caffeine. Whether this interaction will occur in humans is unclear.

Likelihood Possible Evidence D
Codeine

Theoretically, anise oil might increase the effects and adverse effects of codeine.
Animal research shows that anise oil increases the analgesic effects of codeine, possibly by inducing its phase I metabolism and increasing conversion to morphine. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, anise might interfere with contraceptive drug therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.

Likelihood Possible Evidence D
Diazepam (Valium)

Theoretically, anise oil might increase the effects and adverse effects of diazepam.
Animal research shows that taking anise oil with diazepam increases the motor impairment associated with diazepam, possibly by inhibiting its breakdown by cytochrome P450 3A4. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Estrogens

Theoretically, anise might interfere with estrogen-based hormone replacement therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.

Likelihood Possible Evidence D
Fluoxetine (Prozac)

Theoretically, anise oil might decrease the efficacy of fluoxetine.
Animal research shows that taking anise oil with fluoxetine reduces the antidepressant effects of fluoxetine, possibly by promoting its breakdown by cytochrome P450 2D6. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Imipramine (Tofranil)

Theoretically, anise oil might decrease the efficacy of imipramine.
Animal research shows that taking anise oil with imipramine reduces the antidepressant effects of imipramine, possibly by promoting its breakdown by cytochrome P450 2D6. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, anise oil might increase the effects and adverse effects of midazolam.
Animal research shows that taking anise oil with midazolam increases the motor impairment associated with midazolam, possibly by inhibiting its breakdown by cytochrome P450 3A4. Whether this interaction occurs in humans is unclear.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, anise might interfere with tamoxifen therapy.
Some in vitro research suggests that anise has estrogenic effects, while other in vitro research suggests that anise has antiestrogenic effects.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Theoretically, anise oil might decrease the levels and clinical effects of acetaminophen.
Animal research shows that taking anise oil with acetaminophen decreases peak plasma levels of acetaminophen but does not reduce overall bioavailability. Whether this interaction will occur in humans is unclear.

Sleep by Eclectic Herb: Common Questions

Does Sleep by Eclectic Herb interact with any medications?
Yes. Based on its ingredients, Sleep has a known interaction with 1,071 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sleep contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this make me drowsy the next day?
Drowsiness is a common side effect of valerian, passionflower, hops, and chamomile, especially in people who are sensitive to them. Since this is a liquid blend, how much you take matters — start with a smaller dose if you're concerned. If next-day grogginess happens, try taking it earlier in the evening or use a lower dose.
Is this safe if I'm pregnant or nursing?
No. Valerian, hops, passionflower, and chamomile are all best avoided during pregnancy because we don't have enough safety data. While anise is rated likely safe in pregnancy, the blend also contains ingredients we advise against. For breastfeeding, safety information is limited or unavailable for most of these ingredients. Talk to your doctor or pharmacist for personalized guidance.
Can I take this with my other medications?
This blend interacts with a lot of medication types — including sedatives, blood thinners, birth control, diabetes drugs, and some antidepressants. Don't assume it's safe just because the bottle says "natural." Use the medication checker on this page with your exact drugs, or ask your pharmacist before you start.
How long can I take this safely?
The data we have focuses on short-term use. Long-term safety of valerian, hops, passionflower, and chamomile isn't well studied. If you plan to use this for more than a few weeks, talk to your pharmacist about whether that's right for you. Also, stopping abruptly after extended use can cause withdrawal symptoms like anxiety or insomnia — taper slowly instead.
What's a proprietary blend, and why don't I see the amounts?
A proprietary blend is a mix of ingredients where the manufacturer keeps the exact amounts of each one secret to protect their formula. That means you don't know how much valerian, anise, hops, passionflower, or chamomile you're actually getting in each dose — which also makes it harder to predict side effects or interactions.
Is this product checked for quality or purity?
The facts we hold don't include quality, purity, or third-party testing information. That's a good question to ask the manufacturer directly or to research before you buy.
