HelloPharmacist Scorecard of Borage by Herbal Terra

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: a certified organic borage liquid extract made from the dried flower and herb. Borage (Borago officinalis) is a flowering plant whose seed oil and other parts have been studied for various health purposes.

The product also includes menstruum, an inactive ingredient used as the liquid base for the extract.

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 Borage product and its label doesn't state a use — see Borage'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 for borage is mixed and limited. For atopic dermatitis (eczema), the data suggests it's possibly ineffective.

For attention deficit-hyperactivity disorder (ADHD), acute respiratory distress syndrome (ARDS), and alcoholism, there isn't enough reliable evidence to rate whether it works. If you're considering borage for any of these conditions, talk with your doctor about what the current research actually supports.

The evidence, ingredient by ingredient Borage

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.

Borage seed oil by itself is generally well tolerated, though some people experience mild digestive side effects like belching, bloating, soft stools, or diarrhea. The real safety concern is with other parts of the borage plant — the leaf, flower, and seed can contain pyrrolizidine alkaloids, compounds that may damage your liver, especially with long-term use.

The safety data advises against use during pregnancy because of possible liver-toxic alkaloids and theoretical uterine risk. If you're pregnant or breastfeeding, don't use this product without talking to your doctor or pharmacist first.

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 — Borage.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 227 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 take this borage extract, check with your pharmacist or doctor if you use blood thinners or antiplatelet drugs (like warfarin or aspirin) — borage may increase bleeding risk. Also flag any antipsychotic medications (phenothiazines) and any drugs that induce CYP3A4, since borage may raise levels of toxic plant compounds with these combinations.

No interactions are documented for other medication types in our data.

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.

Borage liquid extract may appeal to people exploring herbal remedies, but you should be cautious if you take blood thinners, antipsychotics, or medications that induce CYP3A4. The liver-toxin risk from pyrrolizidine alkaloids is real, especially over time.

Check your exact medications with your own doctor or pharmacist before starting, and avoid it entirely if you're pregnant or nursing.

Anticoagulant/Antiplatelet Drugs

Theoretically, borage seed oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In healthy individuals, borage seed oil supplementation does not seem to affect platelet aggregation. However, gamma-linolenic acid, a constituent of borage seed oil, seems to decrease platelet aggregation by 45% and increase the risk of bleeding by 40% in animal and clinical research.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Inducers

Theoretically, taking borage with drugs that induce CYP3A4 might increase levels of pyrrolizidine alkaloid (PA) toxic metabolites.
Although borage seed oil contains little to no PAs, some borage plant parts, such as the leaf, flower, and seed, can contain hepatotoxic PAs. Hepatotoxic PAs are substrates of CYP3A4, which converts these chemicals into toxic metabolites. Tell patients to avoid borage preparations that are not certified and labeled as hepatotoxic PA-free.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, taking borage sed oil with phenothiazines might increase the risk of seizures.
Borage seed oil contains gamma-linolenic acid (GLA). There is concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines. This is based on limited data from two reports published in the 1980s. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with evening primrose, another source of GLA. However, none experienced an actual seizure. In the other report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily was added. One of these patients had a prior history of seizures. It is unclear whether evening primrose had any additive epileptogenic effects with the phenothiazines, but there is no evidence that taking GLA-containing supplements alone can cause seizures.

Borage by Herbal Terra: Common Questions

Does Borage by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Borage has a known interaction with 226 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Borage 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 this borage product contain liver-toxic alkaloids?
Borage seed oil contains little to no pyrrolizidine alkaloids (the toxic compounds), so it's generally the safer form. However, this product is a whole-plant extract made from flower and herb, which may contain these alkaloids. Look for products certified PA-free to reduce that risk.
What side effects should I expect?
Most people tolerate borage seed oil well, but you might notice belching, bloating, soft stools, or diarrhea. In rare cases, if you're taking other borage plant parts with higher alkaloid levels, liver damage is a serious concern — another reason to choose a certified PA-free product and avoid long-term use without your doctor's oversight.
Can I take borage while I'm pregnant?
No — the safety data advises against it during pregnancy because of possible liver-toxic alkaloids and a theoretical risk to the uterus. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before using any borage product.
Does borage work for eczema or ADHD?
For eczema, the evidence suggests it's possibly ineffective. For ADHD, we don't have enough reliable data to say whether it works. If you're considering borage for either condition, discuss it with your doctor — there may be more established treatments available.
Is breastfeeding safe while taking borage?
There isn't enough safety data to know either way, and the risk of PA contamination is a concern. Talk with your doctor or pharmacist before using borage while nursing.
