HelloPharmacist Scorecard of Safflower 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: certified organic Safflower (Carthamus tinctorius) dried petals in liquid extract form. Safflower petals have been used in herbal practice for various cardiovascular and metabolic purposes.

The product also contains menstruum, an inactive ingredient used as a solvent to extract and deliver the herb.

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 Safflower product and its label doesn't state a use — see Safflower'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 establish that safflower is effective for the conditions it's traditionally used for. The data lists effectiveness ratings for unstable angina, coronary heart disease, cystic fibrosis, diabetes, and diabetic nephropathy—all rated as having insufficient reliable evidence to rate.

This means the clinical studies available don't yet support or refute benefit for these uses.

The evidence, ingredient by ingredient Safflower

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.

Safflower oil from food is generally well tolerated, but concentrated flower extracts and high-dose supplements have less safety data behind them. The main concern in our data is liver failure—at least 7 case reports link acute liver failure requiring transplant to what appears to be overuse of safflower oil, usually when taken for weight loss.

It's unclear exactly what dose or how long someone took it before liver damage occurred. During pregnancy, medicinal amounts of safflower flower should be avoided because it may stimulate the uterus and has traditionally been used to bring on menstruation.

There isn't enough reliable information on medicinal safflower while breastfeeding, so it's best avoided beyond normal food use.

Side effects, ingredient by ingredient Safflower

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 — Safflower.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 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, check with your doctor or pharmacist if you're on warfarin or any other blood thinners (anticoagulants or antiplatelet drugs)—safflower may increase bleeding risk, and one case involved serious urinary tract bleeding. Also flag it if you take diabetes medications, since safflower may alter blood sugar control.

Any liver condition should be discussed too.

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.

Safflower extract is worth double-checking if you take blood thinners like warfarin or other anticoagulants, antiplatelet drugs, or diabetes medications—the data shows Moderate-severity interactions with all three categories. Talk with your doctor or pharmacist before you start, especially if you're pregnant, breastfeeding, or have any liver concerns.

Anticoagulant/Antiplatelet Drugs

High doses of safflower oil might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Small clinical studies show that taking safflower oil, approximately 55 grams daily for 2-3 weeks, decreases platelet aggregation. However, taking lower doses of safflower oil, such as 5 grams daily for 4 weeks, does not seem to affect platelet function. In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, safflower oil might alter the effects of antidiabetes drugs.
Some clinical research shows that taking safflower oil 10 grams daily for 3 weeks can increase fasting blood glucose in patients with type 2 diabetes. However, clinical research in patients with metabolic syndrome with or without impaired glucose tolerance shows that taking safflower oil 8 grams daily for 12 weeks reduces fasting glucose levels by around 8 mg/dL. Some clinical research also shows that taking safflower oil 8 grams daily for 16 weeks does not affect fasting glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence B
Warfarin

Theoretically, safflower oil might increase the risk of bleeding when taken with warfarin.
In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.

Safflower by Herbal Terra: Common Questions

Does Safflower by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Safflower has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Safflower 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.
Can I take this if I'm pregnant?
The data on safflower in pregnancy is mixed—some evidence suggests it's likely safe, while other evidence rates it possibly safe or possibly unsafe. Medicinal amounts of safflower flower should be avoided because it may stimulate the uterus and bring on menstruation. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy.
Is safflower safe while breastfeeding?
There isn't enough reliable information on medicinal safflower during breastfeeding, so it's best to avoid it beyond normal food use. Discuss it with your doctor or pharmacist before taking it.
What side effects has safflower been linked to?
The main concern in our data is liver failure—at least 7 case reports link acute liver failure requiring transplant to what appears to be overuse of safflower oil, usually for weight loss. It's unclear exactly what dose or duration caused the liver damage. Safflower oil from food is generally well tolerated, but concentrated extracts and high-dose supplements have less safety data.
Does this product actually work for heart disease or diabetes?
The evidence we hold doesn't establish that safflower is effective for these conditions. The data rates safflower as having insufficient reliable evidence for unstable angina, coronary heart disease, cystic fibrosis, diabetes, and diabetic nephropathy—meaning the clinical studies available don't yet support or refute benefit.
What's in this liquid besides the safflower?
The inactive ingredient is menstruum, a solvent used to extract and deliver the herb. There are no other fillers or binders listed.
