HelloPharmacist Scorecard of Common Ivy by TerraVita

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 Glycerite Liquid Extract (English ivy). It's made as a glycerite, which means the herb is extracted using glycerin as the solvent.

The only other ingredient is glycerin, which is an inactive carrier.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Cough, bronchitis, and respiratory support.
  • We looked for evidence on: Bronchitis, Cough, Respiratory tract infections, Chest congestion, Asthma, Sore throat.
  • 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 we hold on English ivy for the conditions it's traditionally used for—bronchitis, respiratory infections, gout, spasticity, and neuropathic pain—is insufficient to rate how well it works. That doesn't mean it doesn't work; it means reliable studies haven't been done or aren't available in our data.

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.

Standardized leaf extracts like this one are generally well tolerated when taken by mouth. The most common side effects reported are abdominal pain, diarrhea, nausea, and vomiting.

Skin irritation can occur with oral use, and allergic reactions or contact dermatitis are possible. There isn't enough safety information to use this product during pregnancy, so it's best avoided.

Safety while breastfeeding is also unknown—avoid it unless your doctor directs otherwise.

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.

Check with your pharmacist before starting if you take any medications metabolized by the liver enzymes CYP2C19, CYP2D6, or CYP2C8. This includes many antidepressants, heart medications, blood pressure drugs, pain relievers, and diabetes medicines.

These interactions are theoretical and haven't been reported in people yet, but your pharmacist can look up your exact drugs to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Common Ivy may be worth discussing with your pharmacist if you're interested in traditional respiratory or joint support—but the evidence for how well it works isn't established in the data we hold. Before you start, check your medications, especially any that your liver processes through CYP2C19, CYP2D6, or CYP2C8 enzymes, since English ivy may slow how fast your body clears them.

If you're pregnant or breastfeeding, talk to your doctor first.

Common Ivy by TerraVita: Common Questions

Does Common Ivy by TerraVita interact with any medications?
Yes. Based on its ingredients, Common Ivy has a known interaction with 280 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Common Ivy 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.
What exactly is in this bottle?
One active ingredient: English ivy extract made as a glycerite (extracted using glycerin). Glycerin is the only other ingredient—it's the liquid carrier.
Does this actually work for cough or chest congestion?
The evidence we hold on English ivy for respiratory infections and bronchitis is insufficient to rate—meaning reliable studies haven't been done or aren't available in our data. You'd want to talk with your doctor about whether it's a good choice for you.
Can I take this while pregnant?
No. There isn't enough reliable safety information, so it's best avoided during pregnancy. Talk to your doctor if you're pregnant or planning to be.
What side effects should I watch for?
The most common are abdominal pain, diarrhea, nausea, and vomiting. Skin irritation can also occur. If any of these happen, stop taking it and let your pharmacist know.
Is this safe to take with my medications?
It depends on what you take. English ivy may slow how your liver clears certain drugs—potentially building them up to higher levels. Use the medication checker on this page with your exact prescriptions, and ask your pharmacist if you're unsure.
