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.

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 product contains one active ingredient: Asafoetida Herb Extract, Dry — a resinous plant material traditionally used in herbal practice. The liquid formulation also includes alcohol, water, and glycerin as inactive ingredients to deliver the extract.

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 product facts we hold do not include effectiveness ratings for asafoetida, so we can't tell you from our data whether it works for any particular use.

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 in food amounts appears to be generally well tolerated. At medicinal doses, though, the safety data is thin — we don't have solid information on how safe higher amounts really are.

Large doses have been tied to swelling of the lips, belching, gas, diarrhea, headache, and in rare cases convulsions. Doses of 50–100 mg specifically have caused headache or convulsions in reports.

Asafoetida has also been associated with a serious blood condition (methemoglobinemia) in infants, including one documented case of a 3-month-old given asafoetida for colic who developed dangerously high levels and required intensive care — though he recovered fully. Topically, it's been reported to cause genital swelling.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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.

Check your blood pressure medications (captopril, enalapril, losartan, valsartan, diltiazem, and others) and any blood thinners or antiplatelet drugs (aspirin, clopidogrel, warfarin, ibuprofen, naproxen, enoxaparin, and others) before you start this product — both categories carry Moderate interaction risk.

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 documented interactions involving blood pressure control and bleeding risk. If you take antihypertensive or anticoagulant drugs, you'll want to check this with your pharmacist before starting.

Pregnant people and those breastfeeding should avoid medicinal doses — the safety data advises against it. Talk to us before you use it.

Asafoetida Herb Extract, Dry2 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 asafoetida while I'm pregnant?
No. The safety data advises against medicinal amounts of asafoetida during pregnancy — it's traditionally been avoided and hasn't been proven safe at those doses. Stick with your doctor or midwife for what's right for you.
Is it safe to use while breastfeeding?
No. There isn't enough safety information to recommend asafoetida supplement doses while you're breastfeeding, so it's best to avoid it during that time.
What are the side effects I should watch for?
In larger amounts, asafoetida can cause gas, belching, diarrhea, swelling of the lips, headache, or rarely convulsions. Infants have developed a serious blood condition (methemoglobinemia) from it, so don't give this to babies. At doses of 50–100 mg, headache or convulsions have been reported.
Why does this product interact with so many medications?
The single active ingredient — asafoetida — theoretically affects how your blood pressure is regulated and your blood's clotting ability. Those two systems involve a lot of different drug types, which is why the total interaction count is high even though we're only talking about two categories of concern.
What is asafoetida used for?
Asafoetida is a traditional herbal extract, but we don't hold effectiveness data on this product that tells us what it works for — that's something to ask your herbalist or pharmacist about.
