HelloPharmacist Scorecard of Ashwagandha by Herbs Etc.
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
This product contains one active ingredient: ashwagandha, an herb traditionally used in Ayurvedic medicine. The liquid is prepared in a base of grain alcohol and purified water.
Does it work?
Moderate evidence
Ashwagandha is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder (GAD), according to the evidence we have on file. For bipolar disorder, the evidence isn't strong enough to rate.
How safe is it?
Well-documented data
Ashwagandha is generally well tolerated in the short term by healthy adults, though long-term safety data are limited. Stomach upset, nausea, diarrhea, and vomiting can occur, but these don't happen with typical doses.
Rare serious side effects include liver injury and, in case reports, drowsiness and headache. The safety data advises against use during pregnancy because it's traditionally thought to carry miscarriage risk.
There isn't enough information to know whether it's safe while breastfeeding — talk with your pharmacist for personalized advice.
Meds to double-check
Moderate interaction found
Before taking this product, check your exact medications with your pharmacist if you take CNS depressants or sedatives (including benzodiazepines), blood pressure medications, diabetes medications, thyroid hormone, immunosuppressants, or any drug that affects the liver. The biggest concern is liver risk.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Ashwagandha may help with insomnia, anxiety, and stress. If you take any prescription medications — especially sedatives, blood pressure drugs, diabetes medications, immunosuppressants, thyroid hormone, or liver-metabolized drugs — check with your pharmacist first.
People who are pregnant, planning pregnancy, or breastfeeding should talk with their doctor or pharmacist before using it.

Ashwagandha by Herbs Etc. Drug Interactions
HelloPharmacist Interaction Report
Ashwagandha by Herbs Etc. has documented interactions with seven categories of medications.
The most serious concern is with hepatotoxic drugs (medications that can damage the liver) — ashwagandha itself has been linked to liver injury in rare cases, and combining it with drugs that carry liver risk theoretically increases that danger further.
Read the full breakdown — every affected drug type, severity by severity
Major concerns also include CNS depressants (sedatives, sleep aids, and anxiety medications like benzodiazepines), which ashwagandha may enhance, raising the risk of over-sedation. It may also lower blood pressure when combined with antihypertensive drugs, and could interfere with blood sugar control when taken with antidiabetes medications — both Moderate-severity interactions.
Ashwagandha has immune-stimulating properties that theoretically may reduce the effectiveness of immunosuppressants, and it may boost thyroid hormone levels, potentially causing or worsening hyperthyroidism in people already on thyroid replacement therapy.
One minor interaction involves a specific liver enzyme (CYP1A2 substrates) — ashwagandha may lower the levels of certain medications processed by that pathway. Altogether, these interactions span 1,351 individual medications.

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
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.
