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.

From our pharmacy team — supplement deep dive

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 product contains one active ingredient: elderberry extract. Elderberry comes from the fruit of the elder plant and has been used traditionally to support immune and respiratory health.

The syrup form includes honey, grain alcohol, and purified water as inactive ingredients that help preserve and deliver the extract.

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: supporting natural defenses.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Lower respiratory tract infections, Respiratory tract infections, immune function, colds, flu.
  • 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's benefits isn't yet strong enough to rate reliably. Our data shows insufficient evidence for hay fever, heart disease, chronic fatigue, COPD, brain function, and common respiratory infections.

That doesn't mean elderberry doesn't work — it means larger, well-designed studies are needed to know how well it performs for these uses.

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 are generally well tolerated. Nausea and vomiting can occur, but they're typically linked to raw or unripe berries, seeds, leaves, or other plant parts — not prepared extracts like this syrup.

The facts do note one case of a patient with underlying autoimmune disease who developed liver inflammation after long-term use and recovered after stopping the product. Because there isn't enough safety data, avoid elderberry supplements during pregnancy and while breastfeeding — talk with your doctor or pharmacist about whether it's right for you during these times.

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.

Check with your doctor or pharmacist before using this product if you take immunosuppressants or pazopanib (Votrient). These are the two drug types with documented interactions in our data.

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.

Elderberry syrup is generally well tolerated when properly prepared. But if you take an immunosuppressant (such as after a transplant) or pazopanib for cancer, you'll need to clear this with your doctor or pharmacist first — the interactions could reduce how well your medication works or increase side effects.

For other medications or health situations, check your exact drugs in the tool below before starting.

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.
