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 10 active ingredients.

Neural-Ease contains 10 active herbal ingredients: rhodiola, hawthorn, blessed thistle, white pond lily, blue cohosh, prickly ash, lobelia, blue vervain, black cohosh, and condurango. The product is formulated as a liquid and also contains alcohol and glycerin as inactive ingredients.

These herbs are traditionally used to support relaxation and nervous system function, though the evidence for most claims is not well established in modern research.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Menopausal symptoms — rated "Possibly Effective" (Black Cohosh) (Natural Medicines).

The evidence supporting these ingredients is limited. Black cohosh is possibly effective for menopausal symptoms, but most other uses listed — including anxiety, arrhythmia, cardiovascular conditions, cognitive function, dyspepsia, and back pain — have insufficient reliable evidence.

Lobelia is considered possibly ineffective for smoking cessation. For the remaining ingredients and uses, the data we hold does not establish effectiveness.

The evidence, ingredient by ingredient Rhodiola Hawthorn Blessed Thistle White Lily Blue Cohosh Northern Prickly Ash Lobelia Black Cohosh

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 6 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Rhodiola and hawthorn are generally well tolerated for short-term use, though long-term safety isn't well studied. Minor side effects can include dizziness, dry mouth, or excessive saliva production.

Blue cohosh and lobelia carry stronger cautions: both can cause serious adverse effects including chest pain, elevated blood pressure, heart rate changes, and gastrointestinal upset, and lobelia can be toxic at higher doses. Black cohosh is generally well tolerated short-term but rare liver concerns warrant medical oversight.

Blessed thistle may cause stomach upset or nausea at higher doses. White pond lily and condurango have very limited safety data.

Pregnancy and breastfeeding are not advised for most ingredients due to insufficient safety data or uterotoxic concerns; blue cohosh and lobelia are considered likely unsafe in pregnancy and lactation.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 7 of the 9 matched ingredients can interact with medications — Northern Prickly Ash, Blessed Thistle, Lobelia, Hawthorn, Black Cohosh, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,511 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 Neural-Ease, check with your pharmacist if you take nitrates or phosphodiesterase-5 inhibitors (Major risk), antihypertensive drugs, blood thinners (anticoagulants or antiplatelets), diabetes medications, beta-blockers, calcium channel blockers, digoxin, hepatotoxic drugs, atorvastatin, cisplatin, estrogen therapy, serotonergic antidepressants, lithium, or acid-suppressing medications (H2-blockers, antacids, proton pump inhibitors).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

If you take any blood pressure medications, blood thinners, diabetes drugs, heart medications, antidepressants, or estrogen therapy, check your specific medications with the interaction tool before starting Neural-Ease. The ingredients blue cohosh and lobelia carry serious cardiovascular and toxicity risks and warrant extra caution.

Rhodiola10 drug types · 1,271 drugs

Antidiabetes Drugs

Theoretically, taking rhodiola with antidiabetes drugs might increase the risk of hypoglycemia.
In vitro and animal research shows that rhodiola extract can decrease blood glucose due to alpha-glucosidase activity.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking rhodiola with antihypertensive drugs might increase the risk of hypotension.
In vitro and animal research shows that rhodiola extract inhibits angiotensin-converting enzyme (ACE) and might lower blood pressure.

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

Theoretically, rhodiola might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that rhodiola inhibits CYP2C9. This effect is highly variable and appears to be dependent on the rhodiola product studied. Also, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, rhodiola use might interfere with immunosuppressive therapy.
In vitro and animal research show that rhodiola has immunostimulatory effects.

Likelihood Possible Evidence D
Losartan (Cozaar)

Rhodiola might increase the levels and adverse effects of losartan.
A clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Theoretically, rhodiola might increase levels of P-glycoprotein substrates.
In vitro research shows that rhodiola inhibits P-glycoprotein. Theoretically, using rhodiola with P-glycoprotein substrates might increase drug levels and potentially increase the risk of adverse effects.

Likelihood Possible Evidence D
Antidepressant Drugs

Theoretically, rhodiola might increase the risk of adverse effects when taken with antidepressants.
A review of adverse event reports in Poland identified cases of tachyarrhythmias, myalgia, arthralgia, gum pain, restless leg syndrome, swallowing disorders, and changes in consciousness when rhodiola was taken in combination with paroxetine, escitalopram, fluoxetine, sertraline, trazodone, and/or duloxetine.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.

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

Theoretically, rhodiola might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that rhodiola inhibits CYP1A2. This effect is highly variable and appears to be dependent on the rhodiola product studied. However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of caffeine, a CYP1A2 substrate.

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

Theoretically, rhodiola might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that rhodiola inhibits CYP3A4. This effect is highly variable and appears to be dependent on the rhodiola product studied. However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of midazolam, a CYP3A4 substrate.

Likelihood Possible Evidence B
Rhodiola full monograph & interactions

Black Cohosh7 drug types · 652 drugs

Atorvastatin (Lipitor)

Taking black cohosh with atorvastatin might increase the risk for elevated liver function tests.
In one case report, a patient taking atorvastatin (Lipitor) developed significantly elevated liver function enzymes after starting black cohosh 100 mg four times daily. Liver enzymes returned to normal when black cohosh was discontinued. It is unclear whether the elevated liver enzymes were due to black cohosh itself or an interaction between atorvastatin and black cohosh.

Likelihood Possible Evidence D
Cisplatin (Platinol-Aq)

Theoretically, black cohosh may reduce the clinical effects of cisplatin.
Animal research suggests that black cohosh might decrease the cytotoxic effect of cisplatin on breast cancer cells.

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

Some research suggests that black cohosh might inhibit CYP2D6, but there is conflicting evidence.
Some clinical research suggests that black cohosh might modestly inhibit CYP2D6 and increase levels of drugs metabolized by this enzyme. However, contradictory clinical research shows a specific black cohosh product (Remifemin, Enzymatic Therapy) 40 mg twice daily does not significantly inhibit metabolism of a CYP2D6 substrate in healthy study volunteers. Until more is known, use black cohosh cautiously in patients taking drugs metabolized by CYP2D6.

Likelihood Possible Evidence B
Estrogens

Theoretically, black cohosh may alter the effects of estrogen therapy.
Some research suggests that black cohosh has estrogenic effects. This may enhance or inhibit the effects of estrogen therapy.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
There is concern that black cohosh might be linked to cases of liver failure and autoimmune hepatitis.

Likelihood Possible Evidence D
Serotonergic Drugs

Combining serotonergic drugs with black cohosh might cause additive serotonergic effects.
Black cohosh might increase the risk of serotonin syndrome when combined with other serotonergic drugs. Black cohosh acts as an agonist at several serotonin receptor subtypes and might interact with other serotonergic medications. In one case, a 55-year-old female who had been on stable treatment with sertraline 50 mg and duloxetine 60 mg daily developed serotonin syndrome after taking black cohosh extract 40 mg daily for 3 days.

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

Black cohosh may inhibit one form of OATP, OATP2B1, which could reduce the bioavailability and clinical effects of OATP2B1 substrates.
In vitro research shows that black cohosh modestly inhibits OATP2B1. OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.

Likelihood Possible Evidence D
Black Cohosh full monograph & interactions

Blue Cohosh3 drug types · 259 drugs

Antidiabetes Drugs

There is some concern that blue cohosh might increase blood glucose levels. Theoretically, it might decrease the effectiveness of medicines used for diabetes. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

Likelihood Possible Evidence D
Antihypertensive Drugs

Constituents in blue cohosh might increase blood pressure by causing coronary vasoconstriction. Theoretically, concomitant use might decrease the effectiveness of drugs used for angina and high blood pressure; use with caution. Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

Likelihood Possible Evidence D
Nicotine

Blue cohosh can increase the effects of nicotine.

Likelihood Possible Evidence D
Blue Cohosh full monograph & interactions

Hawthorn6 drug types · 191 drugs

Nitrates

Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Probable Evidence D
Phosphodiesterase-5 Inhibitors

Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.

Likelihood Possible Evidence D
Beta-Blockers

Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.

Likelihood Possible Evidence D
Calcium Channel Blockers

Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.

Likelihood Possible Evidence D

Theoretically, blessed thistle might decrease the effectiveness of antacids.
There are reports that blessed thistle increases stomach acid.

Neural-Ease by Earth Friend Herb Co.: Common Questions

Does Neural-Ease by Earth Friend Herb Co. interact with any medications?
Yes. Based on its ingredients, Neural-Ease has a known interaction with 1,510 medications, including 14 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Neural-Ease contains 10 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.
Is Neural-Ease safe during pregnancy or while breastfeeding?
No. The safety data is insufficient for most ingredients, and several — particularly blue cohosh and lobelia — are considered likely unsafe in pregnancy due to potential uterine effects and toxicity risks. Talk with your doctor before using this product if you're pregnant, planning pregnancy, or breastfeeding.
What are the most common side effects?
Rhodiola may cause dizziness, dry mouth, or excessive saliva production. Blessed thistle in higher doses can cause stomach upset or nausea. Lobelia can trigger nausea, vomiting, diarrhea, dizziness, and throat irritation. Blue cohosh may cause chest pain, elevated blood pressure, and gastrointestinal upset.
Can I use Neural-Ease if I have heart problems?
Not without medical supervision. Hawthorn, blue cohosh, and lobelia all affect heart rate and blood pressure. If you have any heart condition — including high blood pressure, arrhythmia, or angina — discuss this product with your doctor first.
Does black cohosh in this product help with menopause symptoms?
Black cohosh is possibly effective for menopausal symptoms, so it may help. However, the evidence is not conclusive, and individual results vary. Talk with your healthcare provider about whether it's right for your situation.
Is this product meant to treat anxiety?
Both hawthorn and black cohosh are listed for anxiety, but the evidence is insufficient to establish they work for this purpose. If you're dealing with anxiety, check with your doctor about proven options.
What if I'm on lithium for bipolar disorder?
Lobelia in this product theoretically increases lithium levels, which could be dangerous. You should talk with your prescriber before using Neural-Ease if you take lithium.
