HelloPharmacist Scorecard of Organic Ceylon Cinnamon Powder by Herb Affair

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 Jul 11, 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 product contains one active ingredient: Ceylon cinnamon powder. That's it—no other actives.

The inactive ingredients listed are the cinnamon powder itself in its final form.

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 Cassia Cinnamon product and its label doesn't state a use — see Cassia Cinnamon'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 evidence we hold doesn't establish that cinnamon works for any of the conditions listed—amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (high cholesterol). All six show insufficient reliable evidence to rate.

If you're thinking about using cinnamon for one of these, talk with your doctor or pharmacist about what the broader research says.

The evidence, ingredient by ingredient Cassia Cinnamon

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.

Food amounts of cinnamon are generally well tolerated. However, supplement doses—especially high ones over time—carry caution because of coumarin content, which can harm the liver with prolonged use.

In clinical trials of cassia cinnamon at doses from 360 mg to 12 grams daily for up to 3 months, liver enzyme levels didn't rise significantly, but very high coumarin doses (50–7,000 mg per day) have caused liver damage in people that reversed when they stopped. A small number of trial participants reported a rash or, in one case, a hypoglycemic seizure (low blood sugar seizure), though the connection to cinnamon in that seizure case is unclear.

If you have a documented allergy to cinnamic alcohol, dietary cinnamon can trigger systemic contact dermatitis (a whole-body allergic rash). During pregnancy and breastfeeding, food amounts are likely fine, but avoid medicinal or high-dose supplement amounts—there isn't enough safety data for those.

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 — Cassia Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 443 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, double-check your medications if you take any drugs that strain the liver (hepatotoxic drugs) or diabetes medications—both carry moderate interaction risks with cinnamon at supplement doses. Use the medication checker on this page to look up your exact drugs.

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Organic Ceylon Cinnamon Powder by Herb Affair: Common Questions

Does Organic Ceylon Cinnamon Powder by Herb Affair interact with any medications?
Yes. Based on its ingredients, Organic Ceylon Cinnamon Powder has a known interaction with 442 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Ceylon Cinnamon Powder 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.
Is Ceylon cinnamon safe in pregnancy?
Food amounts are likely fine during pregnancy and breastfeeding. However, medicinal or high-dose supplement amounts aren't well studied for safety, so it's best to avoid them and talk with your pharmacist or doctor for personalized advice.
Can cinnamon help lower my blood sugar?
The evidence we hold shows insufficient reliable data to say cinnamon works for diabetes. That said, cinnamon may lower blood glucose, which is why it can interact with diabetes medications—dose adjustments might be needed if you use both.
Are there any side effects I should know about?
In trials, a rash was reported in one person taking 1 gram daily for 90 days. There's also a report of one person experiencing a hypoglycemic seizure (very low blood sugar seizure), though it's unclear if cinnamon caused it. If you have a known allergy to cinnamic alcohol, even dietary cinnamon can trigger an allergic rash.
Is this safe to take long-term?
At food amounts, yes. At supplement doses over a long time, there's caution because cinnamon contains coumarin, which can harm the liver with very high or prolonged intake. Clinical trials at 360 mg to 12 grams daily for 3 months didn't show liver damage, but very high coumarin doses carry risk.
What's the difference between Ceylon and cassia cinnamon?
Our data link Ceylon cinnamon to cassia cinnamon, so the interactions and safety information we hold apply to this product. The two are different species, but we evaluate this product using cassia cinnamon research.
