HelloPharmacist Scorecard of Ashwagandha by Pure Herbs
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 liquid contains one active ingredient: Ashwagandha Root Extract. There are no other inactive ingredients listed.
Does it work?
Moderate evidence
Ashwagandha is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder (GAD) based on the evidence we hold. The data for bipolar disorder is insufficient to rate whether it works.
If you're taking it for sleep or anxiety, keep realistic expectations—the evidence suggests benefit, but it's not a guarantee.
How safe is it?
Well-documented data
Ashwagandha is generally well tolerated in short-term use by healthy adults, though long-term safety data are limited. The most common side effects—diarrhea, nausea, vomiting, and gastrointestinal upset—don't typically occur at standard doses.
Drowsiness has been reported. Rare but serious concerns include acute liver damage, liver failure, and in one case, reversible brain blood vessel narrowing (reversible cerebral vasoconstriction syndrome).
One case report described a person who developed overactive thyroid (hyperthyroidism) after taking ashwagandha for two years. During pregnancy, the safety data advises against it—it's traditionally thought to risk miscarriage.
While breastfeeding, there isn't enough safety information, so avoid it. Talk to your doctor or pharmacist before using this if you're pregnant, planning to become pregnant, or nursing.
Meds to double-check
Moderate interaction found
Before taking Pure Herbs Ashwagandha, double-check with your pharmacist if you're on drugs that suppress your immune system, sedatives or anti-anxiety medications (including benzodiazepines), blood pressure medications, diabetes medications, thyroid hormones, or drugs that stress the liver. Minor caution applies to medications broken down by the liver enzyme CYP1A2.
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.
Ashwagandha may help with sleep, anxiety, and stress if the preliminary evidence holds for you. But if you take sedating medications, blood pressure or diabetes drugs, thyroid hormones, immunosuppressants, or medications broken down by your liver, check your specific prescriptions with your pharmacist first.
Avoid it in pregnancy and while breastfeeding. It's generally well tolerated short-term, but serious liver problems are rare and documented.

Ashwagandha by Pure Herbs Drug Interactions
HelloPharmacist Interaction Report
Pure Herbs Ashwagandha is a single-ingredient product that does interact with several types of medication.
The most serious concern is with drugs that suppress your immune system (immunosuppressants): ashwagandha may reduce how well they work, which could compromise your treatment if you're taking them after an organ transplant or for an autoimmune condition.
Read the full breakdown — every affected drug type, severity by severity
Ashwagandha also carries Moderate-severity interactions with sedating drugs—including benzodiazepines like Valium and Klonopin, other sedatives, and barbiturates—because it may amplify their calming effects and increase drowsiness. It may lower blood pressure when used with blood pressure medications (antihypertensive drugs), raising the risk of low blood pressure (hypotension).
Similarly, it could lower blood sugar (glucose) when combined with diabetes medications, creating a risk of low blood sugar (hypoglycemia). There's also preliminary evidence it might boost thyroid hormone levels, which could intensify both the therapeutic and side effects of thyroid medications.
Ashwagandha has been linked to rare but serious liver damage in case reports, so combining it with drugs that stress the liver (hepatotoxic drugs) warrants caution.
One minor interaction exists with drugs broken down by a liver enzyme called CYP1A2; ashwagandha may lower their levels slightly.
Altogether, these interactions span 1,351 individual medications. Use the search tool below to check your exact prescriptions before starting.

For each ingredient in Ashwagandha 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.
Ashwagandha Root Extract
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
