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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Good Night Herbal Complex contains four active herbal extracts: organic valerian, organic chamomile, organic passion flower, and organic lemon balm. Valerian is traditionally used to support sleep; chamomile is known for its mild calming properties; passion flower is included for its sedative effects; and lemon balm is added for relaxation and mood support.

The product also contains inactive ingredients such as tapioca dextrose, bamboo extract, rice extract blend, maltodextrin, sunflower lecithin, palm oil, and guar gum, which serve as fillers and binders.

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: relaxation and occasional sleeplessness.
  • We looked for evidence on: Insomnia, Anxiety, Stress, Restless legs syndrome (RLS), Adjustment disorders, Benzodiazepine withdrawal — and 4 related terms.
  • The strongest evidence on file: Lemon Balm is rated "Possibly Effective" for Stress (Natural Medicines).
  • Also on file: Valerian is rated "Possibly Effective" for Insomnia.
  • Also on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety, Insomnia.

For sleep, valerian and passion flower are rated possibly effective based on the evidence we hold. Lemon balm is rated possibly effective for stress and mood support.

However, chamomile's effectiveness for anxiety, hay fever, and other uses listed in our data is rated insufficient reliable evidence—meaning the research hasn't yet established whether it works for those purposes. If better sleep is your goal, the valerian and passion flower may help, but results vary from person to person.

The evidence, ingredient by ingredient Valerian German Chamomile Passion Flower Lemon Balm

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Valerian and passion flower are generally well tolerated short-term, though long-term safety isn't well studied. Common side effects include dizziness, drowsiness, headache, and vivid dreams.

Valerian can cause withdrawal symptoms—anxiety, irritability, and insomnia—if you stop suddenly after extended use, so taper your dose slowly. Chamomile may trigger allergic reactions in people sensitive to ragweed and related plants, ranging from itching and watery eyes to severe reactions like anaphylaxis, though this is rare.

Lemon balm is generally well tolerated short-term but may cause dizziness and sedation. Valerian is not established as safe during pregnancy and should be avoided; passion flower is rated possibly unsafe in pregnancy.

Chamomile and lemon balm lack enough safety data in pregnancy—talk with your doctor before using either while pregnant. None of the four ingredients have adequate safety data for breastfeeding, so discuss with your doctor or pharmacist before nursing.

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?
  • 4 of the 4 matched ingredients can interact with medications — Lemon Balm, Valerian, Passion Flower, German Chamomile.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 1,018 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 any blood thinners (especially warfarin), CNS depressants like benzodiazepines or sleep aids, alprazolam (Xanax), alcohol, oral contraceptives, hormone replacement therapy, thyroid hormone replacement, or drugs metabolized by your liver's CYP2D6, CYP2C9, or CYP3A4 enzymes. The Moderate interactions with these drug types are the main concern.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Good Night Herbal Complex may help with sleep if you take it short-term, though the evidence is strongest for valerian and passion flower. Because all four ingredients add to sedation and can interact with numerous medications—especially blood thinners, sleep aids, anti-anxiety drugs, and thyroid medication—you'll want to run your medications through the interaction checker and discuss this product with your own doctor or pharmacist before starting, particularly if you're pregnant, breastfeeding, or take prescription drugs.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, large amounts of German chamomile might reduce the effectiveness of oral contraceptives.
In vitro, German chamomile has demonstrated antiestrogenic activity. Theoretically, concomitant use of large amounts of German chamomile might interfere with contraceptive drugs through competition for estrogen receptors.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, German chamomile might inhibit CYP2C9 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP2C9. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP2C9 in patients taking German chamomile.

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

Theoretically, German chamomile might inhibit CYP3A4 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP3A4. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP3A4 in patients taking German chamomile.

Likelihood Possible Evidence D
Estrogens

Theoretically, large amounts of German chamomile might reduce the effectiveness of estrogens.
In vitro, German chamomile has demonstrated antiestrogenic activity. Theoretically, large amounts of German chamomile might interfere with hormone replacement therapy through competition for estrogen receptors.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, large amounts of German chamomile might interfere with the activity of tamoxifen.
In vitro, German chamomile has demonstrated antiestrogenic activity.

Likelihood Possible Evidence D
Warfarin (Coumadin)

German chamomile might increase the effects of warfarin and increase the risk of bleeding.
In one case, a 70-year-old female taking warfarin developed retroperitoneal hematoma and bilateral recti muscle bleeding along with an INR of 7.9 following ingestion of German chamomile tea 4-5 cups daily and use of a topical chamomile-based lotion applied 4-5 times daily.

Likelihood Possible Evidence D

organic 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.

Likelihood Possible Evidence B
organic Valerian full monograph & interactions

organic Passion Flower extract3 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.

Cns Depressants

Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Lemon balm seems to have CNS depressant activity in animals and in humans.

Likelihood Possible Evidence B
Thyroid Hormone

Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity. In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion.

Good Night Herbal Complex by Sundown Organics: Common Questions

Does Good Night Herbal Complex by Sundown Organics interact with any medications?
Yes. Based on its ingredients, Good Night Herbal Complex has a known interaction with 1,017 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Good Night Herbal Complex contains 4 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.
Can I take this if I'm on birth control?
Chamomile in large amounts may theoretically reduce how well oral contraceptives work by interfering with estrogen receptors. This product contains a standardized extract, so the dose of chamomile may be less of a concern than it would be with large amounts of fresh chamomile tea, but talk with your doctor or pharmacist to be sure.
What if I stop taking this suddenly?
Valerian in particular can cause withdrawal symptoms—anxiety, irritability, insomnia, and rapid heartbeat—if you stop after regular use. Taper your dose slowly over a few days to weeks rather than quitting all at once.
Will this make me drowsy?
Yes. Dizziness, drowsiness, and mental slowness are the most common side effects, especially with valerian and passion flower. Don't drive or operate machinery until you know how it affects you.
Is this safe during pregnancy?
No. Valerian and passion flower are rated as unsafe or possibly unsafe during pregnancy, and chamomile and lemon balm don't have enough safety data. Talk with your doctor before taking any of these ingredients if you're pregnant or planning to become pregnant.
Can I drink alcohol with this?
No. Valerian can add to alcohol's sedative effects, causing extra drowsiness and impaired judgment. Avoid alcohol while taking this product.
Can I use this if I have a thyroid condition?
Lemon balm may theoretically interfere with thyroid hormone replacement therapy. If you take thyroid medication, check with your doctor or pharmacist before starting this product.
