HelloPharmacist Scorecard of Asafoetida by Hawaii Pharm

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Oct 6, 2026

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This is a single-ingredient product: certified organic Asafoetida extract in liquid form. Asafoetida comes from the resin of a plant root and has been used traditionally in herbal medicine.

The liquid is suspended in vegetable glycerin, pharmaceutical-grade alcohol, and purified water.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Asafoetida product and its label doesn't state a use — see Asafoetida's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The data we hold shows insufficient evidence to rate asafoetida for irritable bowel syndrome, polycystic ovary syndrome, or COVID-19. That doesn't mean it doesn't work for these conditions — it means there isn't enough reliable research yet to say one way or the other.

The evidence, ingredient by ingredient Asafoetida

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Asafoetida appears generally well tolerated at food-level amounts, but medicinal doses haven't been well studied. Large amounts have been reported to cause swelling of the lips, belching, gas, diarrhea, headache, or convulsions; doses as low as 50–100 mg have caused headache or convulsions in some reports.

There are also reports of infantile methemoglobinemia (a condition affecting blood oxygen) tied to asafoetida, and topical use has been linked to genital swelling. The safety data advises against this supplement during pregnancy and while breastfeeding, so talk with your doctor or pharmacist before use if either applies to you.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Asafoetida.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 289 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're on blood pressure medications (captopril, enalapril, losartan, valsartan, diltiazem, and others) or blood thinners and antiplatelet drugs (aspirin, clopidogrel, warfarin, ibuprofen, naproxen, enoxaparin, and others). Altogether, these interactions span 289 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Asafoetida is a traditional herbal extract with two documented interactions you need to know about before you take it — especially if you're on blood pressure or blood thinner medications. The evidence for what it actually does isn't established yet in our data.

Check your exact medications with your doctor or pharmacist before you start.

certified organic Asafoetida extract2 drug types · 289 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, asafoetida might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs. Some anticoagulant/antiplatelet drugs include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Antihypertensive Drugs

Evidence from animal research suggests that asafoetida has hypotensive effects. Theoretically, concomitant use may increase therapeutic effects of antihypertensive therapy due to hypotensive activity of asafoetida. Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

Asafoetida by Hawaii Pharm: Common Questions

Does Asafoetida by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Asafoetida has a known interaction with 289 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Asafoetida contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 pregnant or breastfeeding?
No. The safety data advises against asafoetida in medicinal amounts during pregnancy and while breastfeeding. Talk with your doctor or pharmacist for personalized guidance.
What are the most common side effects?
At food amounts, asafoetida is generally well tolerated. At larger medicinal doses, belching, gas, and diarrhea are reported. A small number of reports link it to headache and, rarely, convulsions.
Does asafoetida actually work for IBS or PCOS?
The evidence we hold is insufficient to rate it for either condition. There may be research out there, but we don't have enough reliable data yet to say whether it works.
Is this supplement safe to use with my blood pressure medication?
That depends on which medication you take. Animal research suggests asafoetida can lower blood pressure on its own, so combining it with your prescription could drop your pressure too low. Check the specific medications you take with your doctor or pharmacist before you start.
