HelloPharmacist Scorecard of Borage Leaf Powder 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

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: borage powder. Borage is a plant, and this powder form means you're getting the whole leaf, not just borage seed oil.

There are no other inactive ingredients listed.

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 leaf powder is thin. For atopic dermatitis (eczema), it's rated possibly ineffective.

For attention deficit-hyperactivity disorder (ADHD), acute respiratory distress syndrome, and alcoholism, there simply isn't enough reliable evidence to say whether it works. The data we hold doesn't establish a clear benefit for any of these uses.

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 on its own is generally well tolerated, causing mainly mild digestive side effects like bloating, diarrhea, and belching in some people. However, borage leaf — which is what you're getting in this powder — can contain hepatotoxic pyrrolizidine alkaloids (PA), compounds that may harm your liver with ongoing use.

The facts note that certified PA-free seed oil is better tolerated. This product is rated likely unsafe in pregnancy because of these alkaloids and a theoretical risk to the uterus.

If you're pregnant or breastfeeding, don't take this without talking to your doctor or pharmacist first.

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 — 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 taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs like warfarin or aspirin — borage may increase bleeding risk (Moderate). Also flag if you're on antipsychotics called phenothiazines, which carry a Moderate risk of lowered seizure threshold.

If you take medications that induce CYP3A4 (an enzyme group), borage may increase toxic metabolite levels.

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 leaf powder may be worth a try if you're looking for eczema relief, though the evidence doesn't strongly support it. The bigger concern is liver toxicity from pyrrolizidine alkaloids and interactions with blood thinners, antipsychotics, and certain other drugs.

If you take any prescription medications or have liver concerns, check with your doctor or pharmacist before starting.

Borage, Powder3 drug types · 226 drugs

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 Leaf Powder by TerraVita Premium Collection: Common Questions

Does Borage Leaf Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Borage Leaf Powder 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 Leaf Powder 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.
Is borage leaf powder safe during pregnancy?
No — it's rated likely unsafe. Borage leaf contains compounds that may harm your liver and pose a theoretical risk to the uterus. Talk with your doctor or pharmacist before taking it if you're pregnant or planning to become pregnant.
What side effects can borage powder cause?
Most commonly, bloating, gas, diarrhea, and soft stools. Serious liver damage from pyrrolizidine alkaloids is rare but possible, especially with long-term use. If you notice yellowing of the skin or eyes, dark urine, or persistent abdominal pain, stop and see your doctor.
Does borage leaf powder actually work for eczema?
The evidence suggests it's possibly ineffective for atopic dermatitis (eczema). There's not strong data behind it for this use.
Why is borage leaf riskier than borage seed oil?
Borage seed oil contains little to no pyrrolizidine alkaloids — the liver-toxic compounds. The leaf, flower, and seed of the borage plant can have higher levels, which is why certified PA-free borage seed oil is better tolerated.
Can I take this with my blood thinner?
Not without checking first. Borage may increase bleeding risk if you're on warfarin, aspirin, or other blood thinners. Talk with your doctor or pharmacist before combining them.
