HelloPharmacist Scorecard of Cinnamomum Spp. Cinnamon by Wise Woman Herbals

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1.50 mL) without saying how much of each component you get.

This liquid contains one active ingredient: cinnamon (from the cassia cinnamon monograph). The product also holds inactive ingredients — alcohol, spring water, and glycerine — which help deliver the cinnamon in liquid 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 reliably for any condition. We have insufficient reliable evidence to rate it for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (high cholesterol and triglycerides).

That doesn't mean it's ineffective — just that the scientific support isn't solid enough for us to vouch for it.

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.

Cinnamon is generally well tolerated at food amounts, but supplement doses — especially high-dose or concentrated forms — raise concerns. Because cinnamon contains coumarin, a compound that can harm the liver over time with large amounts taken long-term, be cautious with this product if you already have liver stress or take drugs that stress your liver.

During pregnancy and breastfeeding, food amounts of cinnamon are likely fine, but medicinal or high-dose supplement amounts aren't well studied — talk with your doctor or pharmacist for personalized guidance. In clinical trials, a rash was reported in one person, and in separate cases, cinnamon in the diet triggered skin reactions in adults with cinnamic alcohol allergies.

There's also one report of low blood sugar (hypoglycemia) with seizure in a patient, though it's unclear whether the supplement was responsible.

Side effects, ingredient by ingredient Cassia Cinnamon

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 — 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.

Check this product against any diabetes medications (insulin, sulfonylureas, metformin, or others) — cinnamon may lower blood sugar, and you might need a dose adjustment. Also double-check if you take any drugs that stress your liver (hepatotoxic drugs), since cinnamon contains coumarin, which theoretically adds to that risk with extended high-dose use.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take diabetes medications or drugs that stress your liver, you'll want to check with your pharmacist before adding this. Food-level amounts of cinnamon are well tolerated, but supplement doses — especially over the long term — warrant caution due to coumarin content.

For most uses listed in our data, the evidence isn't strong enough to say whether it works.

Cinnamon2 drug types · 442 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.

Cinnamomum Spp. Cinnamon by Wise Woman Herbals: Common Questions

Does Cinnamomum Spp. Cinnamon by Wise Woman Herbals interact with any medications?
Yes. Based on its ingredients, Cinnamomum Spp. Cinnamon 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?
Cinnamomum Spp. Cinnamon 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 this safe to take while pregnant?
Food amounts of cinnamon are likely fine in pregnancy, but supplement doses like this one aren't well studied enough to know either way. Talk with your doctor or pharmacist about your specific situation before starting.
Is this safe while breastfeeding?
Food amounts of cinnamon are likely fine while breastfeeding, but medicinal or high-dose supplement amounts don't have enough safety data. Check with your pharmacist or doctor for personalized advice.
Does this cinnamon actually lower blood sugar?
We don't have reliable evidence to say whether it works for diabetes. The data we hold rates it as insufficient evidence, so we can't vouch for it.
What side effects have been reported?
In clinical trials, a few people reported a rash and skin reactions. There's also one report of low blood sugar with a seizure, though it's unclear if the cinnamon caused it. Most people taking it didn't report these issues.
Can I take this long-term without worrying about my liver?
Food amounts are fine, but supplement doses — especially over a long time — are a concern. Cinnamon contains coumarin, which can harm your liver if you take large amounts for extended periods. If you're already taking something tough on your liver or have liver problems, be cautious and talk to your pharmacist.
