HelloPharmacist Scorecard of Common Ivy 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: common ivy (English ivy) leaf extract at 450 mg per capsule. The capsules also contain gelatin and water as inactive ingredients.

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 English Ivy's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Cough and respiratory tract health.
  • We looked for evidence on: Bronchitis, Cough, Respiratory tract infections, Chest congestion, Asthma symptoms.
  • The closest evidence on file: English Ivy is rated "Insufficient Reliable Evidence To Rate" for Bronchitis (Natural Medicines).
  • Also on file: English Ivy is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Cough.

The evidence for common ivy isn't established in the data we hold. The product has been studied for bronchitis, respiratory tract infections, gout, spasticity, and neuropathic pain, but all those uses show insufficient reliable evidence to rate whether it actually works.

The evidence, ingredient by ingredient English Ivy

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.

The standardized leaf extract in this product is generally well tolerated when taken by mouth. The most common side effects reported are abdominal pain, diarrhea, nausea, and vomiting.

Skin irritation has also been noted with oral use. Do not use this product during pregnancy—there isn't enough reliable safety information.

Safety during breastfeeding is also unknown, so avoid it unless your doctor has specifically directed you to take it. Be aware that raw English ivy plant material (not the extract in this capsule) can be toxic and cause poisoning or skin reactions.

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 — English Ivy.
  • The most serious interaction on file is rated Moderate.
  • For scale: 280 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 this product, double-check any medications you take that are metabolized by the liver enzymes CYP2C19, CYP2D6, or CYP2C8—English ivy theoretically may raise their blood levels. Use the interaction checker below with your exact medication list, and talk to your pharmacist or doctor if you're unsure.

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.

Common Ivy 450 mg is generally well tolerated when taken as directed, but it theoretically may raise blood levels of drugs processed by three major liver enzymes. This hasn't been seen in humans yet, but the risk is real enough to warrant checking your medications first.

Talk to your pharmacist before starting, especially if you take heart drugs, antidepressants, blood pressure medications, or pain relievers. Avoid it if you're pregnant or breastfeeding.
