HelloPharmacist Scorecard of Cinnamon Bark by Gaia Herbs
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
This product contains one active ingredient: organic cinnamon bark extract from cassia cinnamon. The liquid form also holds organic alcohol and water as inactive ingredients.
Does it work?
Couldn't assess
The effectiveness data we hold doesn't establish whether cassia cinnamon works for any of the conditions listed — amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (high cholesterol) — all show insufficient reliable evidence to rate. If you're considering this supplement for one of those purposes, talk with your pharmacist or doctor about what the current research actually supports.
How safe is it?
Well-documented data
Food amounts of cinnamon are generally well tolerated. At supplement doses, though — especially high doses or long-term use — there's concern about liver harm from the coumarin content.
The safety data advises against using concentrated supplement amounts during pregnancy; food amounts are likely fine. In clinical trials and case reports, a rash occurred in one person taking 1 gram daily, and one person had a low blood sugar seizure (hypoglycemic seizure) in a trial, though the cinnamon's role in that event was unclear.
Rarely, people with a cinnamon allergy have had contact dermatitis (skin inflammation) from dietary cinnamon.
Meds to double-check
Moderate interaction found
Check with your pharmacist if you take hepatotoxic drugs (medications that stress the liver) or antidiabetes drugs (diabetes medications). Both are Moderate interactions — cinnamon may lower blood sugar and might compound liver stress at high doses.
The checker below will tell you if your exact medications are affected.
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.
This supplement might interest you if you're drawn to traditional uses of cinnamon, but the evidence for its effectiveness isn't established in our data. If you take diabetes or liver medications, you'll want to check this product with your pharmacist before starting — the blood-sugar-lowering and liver-stress concerns are real.
Stick to food amounts if you're pregnant or breastfeeding.

Cinnamon Bark by Gaia Herbs Drug Interactions
HelloPharmacist Interaction Report
Gaia Herbs Cinnamon Bark is a single-ingredient liquid extract that does interact with certain medications.
The main concern is hepatotoxic drugs (drugs that can stress the liver). In theory, very large doses of cassia cinnamon over a long time might add to that liver stress, since the cinnamon contains coumarin, a compound that can harm the liver at high doses in humans — though the clinical trials cited used doses up to 12 grams daily for 3 months without significantly raising liver enzymes.
Read the full breakdown — every affected drug type, severity by severity
The second concern is antidiabetes drugs (diabetes medications). Cassia cinnamon may lower blood sugar levels on its own, so it could have an additive effect if you're already taking a medication to bring your glucose down.
Your doctor might need to adjust your diabetes medicine dose if you add this supplement.
Altogether, these interactions span 425 individual medications. Before you start taking this cinnamon supplement, especially if you take liver-support drugs or diabetes medications, run them through the checker on this page.

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.
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.
