HelloPharmacist Scorecard of Black Currant Leaf Mint Flavor 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.

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: black currant leaf glycerite liquid extract. It's the whole botanical concentrate in liquid form.

The product also contains glycerin and mint flavor as inactive ingredients—these are the carrier and flavoring.

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 Black Currant product and its label doesn't state a use — see Black Currant'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 have for black currant leaf doesn't support its use for Alzheimer disease, liver disease, upper respiratory tract infections, cough, or atopic dermatitis (eczema). We hold insufficient reliable evidence to rate it for any of these uses right now.

The evidence, ingredient by ingredient Black Currant

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.

Black currant berries are safe to eat as food, but this is a concentrated supplement, and the safety data is limited. That's why it's important to talk it over with your doctor before you start, especially if you're considering it long-term.

In a trial of about 2,000 people taking black currant seed oil at a higher dose, a small number reported mild diarrhea within the first 2–10 days. There's no safety data on file for pregnancy or breastfeeding, so if either applies to you, check with your doctor or pharmacist for personalized guidance.

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 — Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 140 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 taking this product if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, and others) — black currant may increase bleeding risk. Also double-check if you're taking an antipsychotic medication called a phenothiazine, as the interaction could theoretically affect your seizure risk.

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.

Black Currant Leaf Mint Flavor is generally well tolerated at food doses, but concentrated supplements lack robust safety data. If you're on a blood thinner, antiplatelet drug, or antipsychotic medication, you'll want to confirm with your doctor or pharmacist that this product is right for you before starting.

Anticoagulant/Antiplatelet Drugs

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.

Black Currant Leaf Mint Flavor by TerraVita: Common Questions

Does Black Currant Leaf Mint Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Black Currant Leaf Mint Flavor has a known interaction with 140 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Black Currant Leaf Mint Flavor 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 is black currant leaf extract used for?
Black currant leaf has been studied for several uses — Alzheimer disease, liver disease, upper respiratory infections, cough, and eczema — but we don't have enough reliable evidence right now to say it works for any of them.
Is this safe if I'm not on medication?
Black currant berries are safe to eat as food, but this is a concentrated supplement with limited safety data. It's a good idea to mention it to your doctor before you start, especially if you plan to use it regularly.
What side effects did people experience in trials?
In a large trial, a small number of people taking black currant seed oil reported mild diarrhea a few days after starting. It's one of the few adverse effects we have on record.
Can I take this while pregnant or breastfeeding?
There isn't enough data to know whether this supplement is safe in pregnancy or while breastfeeding. Talk with your doctor or pharmacist for personalized advice if either applies to you.
Why is this product a liquid instead of a capsule?
A glycerite liquid extract dissolves the active compounds in glycerin, which acts as a carrier and preservative. The mint flavor makes it easier to take by mouth.
