HelloPharmacist Scorecard of Calmhills by Herbal Hills

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 9 of its 9 active ingredients.
  • “Processed by the method of Siddha Ghruta in” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Quath Dravya of” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

Calmhills is a 9-ingredient blend centered on ashwagandha, a traditional herb used for relaxation and sleep support. The other active herbs are brahmi (bacopa), gotu kola, and Indian long pepper (pippali), all traditional nerve tonics.

Supporting ingredients include a traditional preparation called go-ghruta (cow ghee), shankhpushpi, and jatamasi, each contributing to the herbal formula. The softgel also contains inactive excipients (cow milk and processing vehicles), which are fillers and capsule materials.

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: Burns — rated "Possibly Effective" (Gotu Kola) (Natural Medicines).
  • On file: Venous insufficiency — rated "Possibly Effective" (Gotu Kola) (Natural Medicines).
  • On file: Anxiety — rated "Possibly Effective" (Ashwagandha) (Natural Medicines).
  • On file: Generalized anxiety disorder (GAD) — rated "Possibly Effective" (Ashwagandha) (Natural Medicines).
  • On file: Insomnia — rated "Possibly Effective" (Ashwagandha) (Natural Medicines).

Ashwagandha in this product is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder (GAD) based on the evidence we hold. The other ingredients—brahmi, gotu kola, and Indian long pepper—do not have reliable evidence in our data for the conditions this product is marketed to address.

Brahmi shows insufficient evidence for cognitive function, ADHD, and other uses; gotu kola shows insufficient evidence for anxiety and Alzheimer disease; and Indian long pepper has no established effectiveness ratings in our files. Overall, ashwagandha carries the strongest evidence signal in this formula.

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 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.

Ashwagandha is generally well tolerated short-term in healthy adults, though long-term safety data are limited. The most common side effects from ashwagandha are mild—diarrhea, nausea, gastrointestinal upset, and vomiting—and occur rarely at typical doses.

Serious but rare cases of acute liver problems have been reported. Henbane, however, is a toxic plant that can cause severe poisoning and death even in small doses; it causes anticholinergic effects like dry mouth and vision problems, and at higher doses can trigger hallucinations, delirium, rapid heartbeat, and coma.

Brahmi is generally well tolerated but may cause abdominal cramps, diarrhea, dry mouth, headache, nausea, and in some trials gastrointestinal upset occurred in 12–30% of participants; it can also cause drowsiness. Gotu kola is generally well tolerated short-term, though rare cases of liver problems have been reported; common side effects are gastric irritation and nausea.

Indian long pepper as a food spice is likely fine, but concentrated supplements lack strong safety data.

Major identified

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

Why this rating?
  • 5 of the 5 matched ingredients can interact with medications — Henbane, Indian Long Pepper, Gotu Kola, Bacopa, Ashwagandha.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,579 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 you start: check all blood pressure medications, diabetes drugs, thyroid hormones, and especially anticholinergic medications (like some antidepressants, antihistamines, and bladder medications) with your pharmacist. Ashwagandha may amplify sedatives and benzodiazepines, reduce immune suppressants, and stress the liver with hepatotoxic drugs.

Brahmi affects how your body breaks down many medications through enzyme systems, and Indian long pepper interacts with blood thinners, heart medications like propranolol and theophylline, and the transplant drug cyclosporine. Gotu kola adds CNS depressant interactions.

Henbane carries Major severity anticholinergic effects—do not use this product if you take anticholinergic drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

If you take blood pressure, diabetes, thyroid, sleep, or anticholinergic medications—or any prescription drug—check your exact medications with our tool before starting this product. Henbane in this formula carries serious toxicity risk and should prompt an immediate conversation with your pharmacist.

Ashwagandha may help with sleep and anxiety, but the overall safety profile depends on what you're already taking and your liver function.

Ashwagandha10 drug types · 1,372 drugs

Antidiabetes Drugs

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.

Likelihood Possible Evidence D
Thyroid Hormone

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.

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

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.

Likelihood Possible Evidence D
Serotonergic Drugs

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Curr Neuropharmacol. 2021 Sep 14; 19: 1468–1495. - A Prospective, Randomized Double-Blind, Placebo-Controlled Study of Safety and Efficacy of a High-Concentration Full-Spectrum Extract of Ashwagandha Root in Reducing Stress and Anxiety in Adults. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3573577/]

Likelihood Possible Evidence C

Brahmi8 drug types · 930 drugs

Anticholinergic Drugs

Theoretically, concurrent use might decrease the effectiveness of both agents.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels, which could counteract the effects of anticholinergic drugs. Similarly, anticholinergic drugs might counteract the cholinergic effects of bacopa.

Likelihood Possible Evidence D
Cevimeline (Evoxac)

Theoretically, bacopa might increase the effects and adverse effects of cevimeline.
In one case, a 58-year-old female taking cevimeline long-term for Sjogren syndrome experienced hyperhidrosis, malaise, nausea, and tachycardia shortly after taking a single dose of bacopa. Symptoms resolved after two days. Cevimeline is metabolized by cytochrome P450 (CYP) 2D6 and CYP3A4, and researchers theorize that bacopa may have inhibited these isoenzymes. However, it is unclear if bacopa causes clinically significant inhibition of either CYP2D6 or CYP3A4.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concurrent use of bacopa with other cholinergic drugs might have additive effects.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels. Theoretically, this could result in additive cholinergic effects when used with cholinergic drugs.

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

Theoretically, bacopa might increase the levels and adverse effects of CYP1A2 substrates.
Research on the effects of bacopa extracts on CYP1A2 enzymes is conflicting. Some in vitro evidence shows that bacopa extract can moderately and non-competitively inhibit CYP1A2, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, bacopa might increase the levels and adverse effects of CYP2C19 substrates.
In vitro evidence suggests that bacopa extract can moderately and non-competitively inhibit CYP2C19 enzymes. It is not known whether this is clinically significant.

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

Theoretically, bacopa might increase the levels and adverse effects of CYP2C9 substrates.
Research on the effect of bacopa extracts on CYP2C9 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and non-competitively inhibit CYP2C9, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.

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

Theoretically, bacopa might increase the levels and adverse effects of CYP3A4 substrates.
Research on the effects of bacopa extracts on CYP3A4 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and competitively inhibit CYP3A4, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, bacopa might have additive effects when used with thyroid hormone.
Animal research suggests that bacopa increases thyroxine (T4) levels in mice by about 40%.

Likelihood Possible Evidence D

Pippali14 drug types · 896 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, Indian long pepper might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research shows that Indian long pepper extract inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, Indian long pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of Indian long pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, Indian long pepper might increase the effects and adverse effects of cyclosporine.
In vitro research shows that piperine, a constituent of Indian long pepper, increases the bioavailability of cyclosporine.

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

Theoretically, Indian long pepper might increase the effects and adverse effects of CYP3A4 substrates.
In vitro research shows that piperine, a constituent of Indian long pepper, inhibits CYP3A4.

Likelihood Possible Evidence D
Nevirapine (Viramune)

Theoretically, Indian long pepper might increase blood levels of nevirapine.
A small pharmacokinetic study shows that piperine, a constituent of Indian long pepper, increases the plasma concentration and systemic exposure of nevirapine. However, no adverse effects were associated with the elevated plasma levels of nevirapine.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Theoretically, Indian long pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of Indian long pepper, can inhibit P-glycoprotein.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, Indian long pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of Indian long pepper, can increase pentobarbitone-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Theoretically, Indian long pepper might increase blood levels of phenytoin.
A small pharmacokinetic study shows that piperine, a constituent of Indian long pepper, increases phenytoin serum levels and slows its elimination.

Likelihood Possible Evidence B
Propranolol (Inderal)

Likelihood Possible Evidence B
Amoxicillin (Amoxil, Trimox)

Theoretically, Indian long pepper might increase the effects and adverse effects of amoxicillin.
Evidence from animal research shows that piperine, a constituent of Indian long pepper, increases the plasma levels of amoxicillin when taken concomitantly.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, Indian long pepper might increase blood levels of carbamazepine.
A small pharmacokinetic study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that a single 20 mg dose of purified piperine, which is a constituent of Indian long pepper, increases carbamazepine levels. Piperine may increase absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or by cytochrome P450 3A4 (CYP3A4) inhibition in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects.

Likelihood Possible Evidence B
Cefotaxime (Claforan)

Theoretically, Indian long pepper might increase the effects and adverse effects of cefotaxime.
Animal research shows that piperine, a constituent of Indian long pepper, increases the plasma levels of cefotaxime when taken concomitantly.

Likelihood Possible Evidence D

Mandukparnee2 drug types · 579 drugs

Cns Depressants

Theoretically, taking gotu kola might increase the sedative effects of CNS depressants.
In vitro research suggests that gotu kola may have sedative effects via binding of GABA receptors.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking gotu kola with hepatotoxic drugs might have additive adverse effects.
There are at least four case reports of hepatotoxicity associated with the use of gotu kola. However, more information is needed to determine if gotu kola was the causative factor in these cases.

Calmhills by Herbal Hills: Common Questions

Does Calmhills by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Calmhills has a known interaction with 1,578 medications, including 195 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Calmhills contains 9 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 Calmhills safe during pregnancy?
No. Ashwagandha is listed as likely unsafe in pregnancy—it's traditionally thought to risk miscarriage. Brahmi and gotu kola don't have enough safety data, so they're best avoided. Henbane is definitely unsafe; its alkaloids are toxic to both mother and baby. Do not use this product if you're pregnant.
Can I breastfeed while taking Calmhills?
It's best to avoid this product while breastfeeding. Ashwagandha, brahmi, gotu kola, and Indian long pepper all lack enough safety information for nursing infants. Henbane is unsafe because its toxic alkaloids may pass into breast milk. Talk to your doctor or pharmacist about safer options.
What are the most common side effects?
From ashwagandha and brahmi, you might experience mild gastrointestinal issues—diarrhea, nausea, stomach upset—or dry mouth and headache. Brahmi can also cause drowsiness. These are usually mild and don't happen at typical doses, but if they do occur and persist, let your pharmacist know.
Will Calmhills make me drowsy?
Possibly. Both ashwagandha and brahmi have been reported to cause drowsiness, and gotu kola's sedative effects are theoretically possible. If you drive or operate machinery, start low and see how you feel before taking it during the day.
Can I take this if I have liver problems?
Be very cautious. Ashwagandha, gotu kola, and henbane have all been linked to liver concerns in rare cases. If you have liver disease or take medications that stress the liver, talk to your pharmacist before using this product.
What is ashwagandha supposed to do in this product?
Ashwagandha is an herbal nerve tonic traditionally used to ease anxiety, stress, and sleep problems. Research suggests it may be helpful for those concerns, though the evidence is preliminary. It's the main active ingredient in Calmhills.
