HelloPharmacist Scorecard of Elder Flower 450 mg by TerraVita Premium Collection

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 11, 2026

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, 450 mg per capsule. Elderberry is the fruit of the elder plant, traditionally used to support various aspects of health.

The capsule itself is made from gelatin and water, which are inactive ingredients that help deliver the herb.

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 Elderberry product and its label doesn't state a use — see Elderberry'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 we hold doesn't establish that elderberry works for any of the conditions it's marketed for — hay fever, heart disease, fatigue, lung disease, thinking and memory, or colds and flu. The data shows insufficient reliable evidence to rate it for each of those.

That doesn't mean it doesn't work; it means the research backing it isn't solid enough to say one way or the other.

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. The risk comes from raw or unripe berries, seeds, leaves, and bark, which contain compounds that can cause nausea, vomiting, severe diarrhea, weakness, dizziness, numbness, and even stupor — but cooking gets rid of that toxin.

There's also one rare case report of liver inflammation tied to long-term elderberry use in someone with an underlying autoimmune disease, so keep an eye on how you feel. During pregnancy and breastfeeding, the safety data isn't solid enough to recommend elderberry.

Talk with your doctor or pharmacist about whether it's right for you in those situations.

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, double-check with your pharmacist if you take immunosuppressants (medications after organ transplant or for autoimmune disease) or pazopanib (Votrient) for cancer. Both carry moderate interaction risks with this product.

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.

Elderberry is generally well tolerated when it's properly prepared. If you're taking immunosuppressants, pazopanib, or any other prescription medication, check with us first — this product has documented interactions with a large number of 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.

Elder Flower 450 mg by TerraVita Premium Collection: Common Questions

Does Elder Flower 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Elder Flower 450 mg 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?
Elder Flower 450 mg 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 elderberry safe if I'm pregnant or breastfeeding?
There isn't enough reliable safety information to recommend elderberry during pregnancy or breastfeeding. Talk with your doctor or pharmacist about what's right for your situation — they can weigh the facts with you.
What are the side effects of elderberry?
Properly prepared elderberry is generally well tolerated. Problems come mostly from raw or unripe berries, seeds, leaves, and bark — which can cause nausea, vomiting, diarrhea, weakness, dizziness, numbness, or stupor. Cooking eliminates this risk. There's also one rare case of liver inflammation reported after years of use in someone with an underlying autoimmune disease.
Can I take this with my immunosuppressant medication?
Not without checking with your pharmacist first. Elderberry stimulates your immune system, which could theoretically interfere with immunosuppressants. This is a moderate interaction risk that needs a one-on-one conversation with your pharmacist about your specific drug.
Does elderberry actually work for colds or the flu?
The research we have doesn't establish that it does. The evidence for elderberry against respiratory infections is insufficient to rate — we can't say it works or doesn't work based on the data we hold.
What if I eat raw elderberries instead of taking this supplement?
Raw or unripe elderberries, seeds, leaves, and bark contain compounds that can make you sick — nausea, vomiting, diarrhea, weakness, and dizziness. That's why cooking them is important; it eliminates the toxin. This supplement is made from properly prepared elderberry, so it sidesteps that risk.
