HelloPharmacist Scorecard of Black Currant Leaf Strawberry 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.

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: black currant leaf glycerite liquid extract. It also includes glycerin and strawberry flavor as inactive ingredients to improve taste and preserve the extract.

The black currant leaf extract is the ingredient delivering whatever benefit the product may offer. It's suspended in a glycerin base, which is a common and mild preservative in herbal supplements.

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 hold doesn't yet support claims that black currant leaf extract works for Alzheimer disease, liver disease, upper respiratory tract infection, cough, or atopic dermatitis (eczema). All of those conditions show insufficient reliable evidence in our data.

That doesn't mean it won't help — just that strong clinical proof isn't on file yet.

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.

The safety data here is thin. Black currant as a food is generally well tolerated, but concentrated supplements like this one haven't been studied as thoroughly.

The caution notes make clear: food amounts are probably fine, but supplements lack solid safety information, so you should check with your doctor first. In one trial, a small number of people taking black currant seed oil reported mild diarrhea 2 to 10 days after starting.

Pregnancy and lactation safety information isn't on file for this ingredient, so there's no data to know either way — talk with your doctor or pharmacist for personalized advice if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Black Currant

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 before taking this product if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin) — the GLA in black currant may increase bleeding risk, and this is a Moderate interaction. Also check if you take phenothiazines, a psychiatric medication — there's a Moderate concern that black currant may lower your seizure threshold.

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.

This is a black currant leaf extract in liquid form with very limited evidence for the conditions it may claim to address. If you take blood thinners, antiplatelet drugs, or phenothiazines, it's essential to check with your own doctor or pharmacist before adding it.

Anyone considering it should also talk it over with their pharmacist first, since the safety data on concentrated supplements is sparse.

Black Currant Leaf Glycerite Liquid Extract2 drug types · 140 drugs

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 Strawberry Flavor by TerraVita: Common Questions

Does Black Currant Leaf Strawberry Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Black Currant Leaf Strawberry 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 Strawberry 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.
Does black currant leaf extract actually work for anything?
The evidence we hold doesn't establish it for Alzheimer disease, liver disease, respiratory infections, cough, or eczema — all show insufficient reliable evidence. That means the science isn't in yet, not that it can't help.
Is this safe to take long-term?
Safety data on concentrated black currant supplements is limited. Food amounts are probably fine, but because we don't have solid long-term safety information, you should check with your doctor before starting, especially if you plan to use it regularly.
What are the side effects?
In one trial, a small number of people reported mild diarrhea 2 to 10 days after starting black currant seed oil. That's the main adverse effect we have on file.
Is this okay if I'm pregnant or breastfeeding?
We don't have safety information on concentrated black currant supplements during pregnancy or lactation. Talk with your doctor or pharmacist for advice tailored to your situation.
What's the glycerin for?
Glycerin is an inactive ingredient that preserves the extract and adds sweetness. Strawberry flavor is there to make the liquid taste better.
