HelloPharmacist Scorecard of Erigeron Cinnamon by Herb 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 Jul 23, 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 2 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (585 mg) without saying how much of each component you get.

This liquid extract contains 2 active ingredients: a proprietary extract blend (which breaks down into individual components listed separately) and erigeron essential oil. The product also includes cinnamon essential oil as an active ingredient.

Certified organic cane alcohol is used as an inactive carrier. The blend and erigeron oil make up the botanical core; we could only assess interactions for the cinnamon essential oil component.

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 Ceylon Cinnamon product and its label doesn't state a use — see Ceylon 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 for cinnamon's effects is weak. For obesity and diabetes, the data we hold rates it possibly ineffective — meaning it hasn't shown clear benefit in reliable studies.

For hay fever, COPD, and common cold, there isn't enough reliable evidence to rate it one way or the other. We hold no effectiveness data for erigeron.

The evidence, ingredient by ingredient Ceylon 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 essential oil is generally well tolerated when taken by mouth, though some people report bloating, indigestion, or nausea. Skin contact with cinnamon oil can irritate or trigger an allergic reaction, especially in people sensitized to cinnamaldehyde (a main component of cinnamon oil).

A rare case of bleeding has been reported after long-term use at high doses. Food amounts of cinnamon are considered likely safe in pregnancy; however, supplement doses haven't been well studied in pregnancy.

For breastfeeding, food amounts are likely safe, but the safety of supplement doses is unknown. Talk with your doctor or pharmacist about whether supplement-strength doses are right for you in either situation.

We hold no safety data for erigeron.

Side effects, ingredient by ingredient Ceylon 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 — Ceylon Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 258 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 before combining with blood pressure medications (antihypertensive drugs) — cinnamon may increase the risk of low blood pressure. Also double-check if you take diabetes medications (antidiabetes drugs), since cinnamon may lower blood sugar further.

We could not check the erigeron essential oil for interactions.

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.

This product may appeal to someone looking for an herbal liquid extract, but the evidence for cinnamon's effectiveness on the listed conditions is limited or absent. If you take medications for blood pressure or blood sugar, check your specific drugs with the tool on this page before starting — cinnamon can theoretically add to their effect.

Have a conversation with your doctor or pharmacist about whether this supplement fits your health plan.

Erigeron Cinnamon by Herb Pharm: Common Questions

Does Erigeron Cinnamon by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Erigeron Cinnamon has a known interaction with 258 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Erigeron Cinnamon contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Does this product actually help with colds or allergies?
For common cold and hay fever, we don't have enough reliable evidence to say whether cinnamon works. For COPD, the same is true. The data we hold simply isn't there to back up a claim either way.
Can I take this if I'm breastfeeding?
Food amounts of cinnamon are likely safe while breastfeeding, but supplement doses haven't been studied enough to know. Talk with your doctor or pharmacist about whether this product is the right choice for you right now.
What side effects should I watch for?
Most people tolerate cinnamon well when taken by mouth. Some report bloating, indigestion, or nausea. If you apply it to your skin, it can cause irritation or an allergic rash in some people.
Is cinnamon actually effective for weight loss or blood sugar control?
The evidence we hold rates cinnamon as possibly ineffective for both obesity and diabetes. That means reliable studies haven't shown it works for those purposes.
What's the erigeron ingredient for?
We don't have effectiveness or safety data on file for erigeron essential oil in this product, so I can't tell you what role it's meant to play or how well it works.
What's in this besides the active ingredients?
The product uses certified organic cane alcohol as a carrier to deliver the extract in liquid form.
