HelloPharmacist Scorecard of Elderberry Syrup by Planetary 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.

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 syrup contains one active ingredient: elderberry extract. Elderberry has been used traditionally to support respiratory and immune health, though the evidence for most of those uses isn't yet established in the data we hold.

The product also contains honey, grain alcohol, and purified water as inactive ingredients (the base and preservative for the liquid form).

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 Elderberry's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: European classic for natural defenses.
  • We looked for evidence on: Respiratory tract infections, Upper respiratory tract infection (URTI), Lower respiratory tract infections, Common cold, Influenza.
  • The closest evidence on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Elderberry is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Lower respiratory tract infections.

The evidence for elderberry isn't established for the conditions studied so far—allergic rhinitis (hay fever), heart disease, chronic fatigue, COPD, memory and thinking, and respiratory infections all show insufficient reliable evidence to rate it. That doesn't mean it doesn't work; it means we don't have enough solid data yet to make a claim.

The evidence, ingredient by ingredient Elderberry

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.

Properly cooked elderberry products like this syrup are generally well tolerated. The real concern is raw or unripe berries, leaves, bark, and seeds, which contain a toxin that causes nausea, vomiting, severe diarrhea, weakness, dizziness, and other symptoms—but cooking (as is done in a prepared syrup) eliminates it.

There isn't enough safety data to know whether elderberry is safe in pregnancy or while breastfeeding, so the safety data advises against it during both. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.

Side effects, ingredient by ingredient Elderberry

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 — Elderberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 121 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 you start, check with your doctor or pharmacist if you take an immunosuppressant medication (used after organ transplant, for rheumatoid arthritis, lupus, or similar conditions) or pazopanib (Votrient) for cancer. Elderberry may interfere with how these drugs work or raise your risk of side effects.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you're not on immunosuppressant therapy or pazopanib, elderberry syrup is generally well tolerated in its cooked form. But if you take any medications, especially immune-suppressing drugs or cancer therapies, check with your pharmacist or doctor first.

Pregnant people and those breastfeeding should avoid it until they've discussed it with their healthcare provider.

Elderberry Extract2 drug types · 121 drugs

Immunosuppressants

Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor.

Likelihood Possible Evidence B
Pazopanib (Votrient)

Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 4 weeks for soft-tissue sarcoma developed severe nausea, loose stools, and elevated alanine transaminase and aspartate transaminase levels and was diagnosed with grade 3 liver injury. The patient reported taking elderberry supplements for 2 years, dose unspecified, and was also taking a multivitamin and a calcium supplement. The patient's symptoms and liver enzyme levels improved upon discontinuation of pazopanib and all supplements. Pazopanib treatment was re-initiated, at a lower dose, with no further evidence of liver injury. It was unclear in this case report if the elderberry supplements were derived from the berry, the flower, or the combination.

Elderberry Syrup by Planetary Herbals: Common Questions

Does Elderberry Syrup by Planetary Herbals interact with any medications?
Yes. Based on its ingredients, Elderberry Syrup has a known interaction with 121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Elderberry Syrup 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 if I'm pregnant or breastfeeding?
There isn't enough safety data to know, so the safety information advises against elderberry during pregnancy and while breastfeeding. Talk with your doctor or pharmacist for personalized advice.
What are the side effects of this elderberry syrup?
Properly prepared elderberry extract (like this one) is generally well tolerated with few side effects. The nausea, vomiting, and diarrhea reported in some cases come from raw or unripe berries or other plant parts—not from a cooked syrup like this.
Does this actually work for colds or the flu?
That's the most common reason people use elderberry, but the evidence isn't solid enough yet to say whether it helps with respiratory infections. We don't have reliable data supporting its use for that.
Can I take this with my other supplements?
We don't have interaction data on how elderberry works with other supplements. If you're taking other herbs or over-the-counter products, mention it to your pharmacist or doctor—they can spot any potential conflicts.
Why is this a liquid instead of a pill?
A liquid syrup makes it easy to measure a dose and swallow, and the honey and alcohol help preserve the elderberry extract. Some people find liquids easier to take than capsules.
