HelloPharmacist Scorecard of Elderberry by Red Moon 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.

From our pharmacy team — supplement deep dive

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.

This liquid contains one active ingredient: Elderberry Extract (also called American Elder). The liquid itself is made up of water and alcohol as inactive ingredients — the alcohol serves as a preservative and extraction solvent for the herb.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see American Elder's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune support and cold and flu symptoms.
  • We looked for evidence on: Common cold, Cough, Sore throat, Fever, Congestion, Flu.
  • The closest evidence on file: American Elder is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).
  • Also on file: American Elder is rated "Insufficient Reliable Evidence To Rate" for Cough, Sore throat.

The evidence for elderberry isn't established in the data we hold. The facts show insufficient reliable evidence to rate it for common cold, cough, asthma, headache, cancer, or flatulence.

That doesn't mean it doesn't work — it means the studies aren't robust enough yet to say either way. If you're considering it for a specific condition, ask your pharmacist or doctor what the current research shows.

The evidence, ingredient by ingredient American Elder

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.

Cooked ripe elderberries and flowers are generally well tolerated. However, raw or unripe berries and other plant parts can be toxic, so make sure you're using a properly prepared product.

The most commonly reported side effects from medicinal amounts are dizziness, nausea, numbness, vomiting, and weakness — though the safety data overall is limited. Elderberry is not recommended during pregnancy or while breastfeeding because there isn't enough reliable safety information.

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 — American Elder.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 645 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 with your pharmacist if you take any medications metabolized by the CYP3A4 enzyme (a large group including certain statins, blood pressure drugs, and immunosuppressants) or if you take lithium. Both carry a Moderate risk.

No other major drug interactions are documented for the ingredients we could check.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Elderberry extract might be worth a try if you're looking for immune support, but the evidence for specific conditions isn't strong yet. If you take any prescription medications — especially those processed by your liver, cholesterol drugs, blood pressure medications, or lithium — you'll want to check with us first.

Talk to your pharmacist before starting, particularly if you're pregnant or nursing.

Elderberry by Red Moon Herbs: Common Questions

Does Elderberry by Red Moon Herbs interact with any medications?
Yes. Based on its ingredients, Elderberry has a known interaction with 644 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Elderberry 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 this if I'm pregnant or breastfeeding?
No. The safety data advises against elderberry during pregnancy and while breastfeeding because there isn't enough reliable information to know it's safe. Talk with your doctor or pharmacist about what's appropriate for you.
What are the side effects?
Common ones from medicinal doses include dizziness, nausea, vomiting, numbness, and weakness. Safety data is limited, so we don't have a complete picture. If you drink several glasses of elderberry juice, nausea and vomiting are more likely.
Does this actually work for colds or cough?
The evidence we have is insufficient to say either way. It's not established that it works for common cold, cough, asthma, headache, or the other conditions people use it for. Your pharmacist can point you to the latest research.
Why does the label say to avoid raw berries?
Raw or unripe elderberries and other parts of the elder plant can be toxic. This product uses cooked ripe berries and is prepared safely, but it's good to know the raw plant isn't safe.
Is the alcohol content a problem?
The product contains alcohol as a solvent and preservative in the liquid. If you need to avoid alcohol — for health, religious, or recovery reasons — let your pharmacist know so they can suggest an alternative form.
