HelloPharmacist Scorecard of American Saffron & Slippery Elm 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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “American Saffron and Slippery Elm Glycerite Liquid Extract” is listed as a grouped ingredient — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This is a two-ingredient liquid blend: American Saffron (safflower) glycerite and Slippery Elm glycerite, both extracted and delivered in glycerin. These are the active ingredients — the glycerin itself is an inactive carrier.

You're getting a concentrated liquid extract of each plant's traditional components, meant to be taken orally.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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 both safflower and slippery elm is insufficient in the data we hold. Safflower has been studied for unstable angina, coronary heart disease, diabetes, and diabetic kidney damage, but reliable evidence isn't there to rate it for any of those.

Slippery elm has been researched for constipation, cough, inflammatory bowel disease, cancer, and diarrhea — again, the evidence doesn't support a clear rating. If you're considering this product for a specific condition, your pharmacist can help you weigh what the broader research literature shows.

The evidence, ingredient by ingredient Safflower Slippery Elm

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Safflower oil in food is generally well tolerated, but concentrated flower extracts and high-dose supplements have less safety data backing them. At least seven case reports link over-use of safflower oil to acute liver failure requiring transplant, though the exact doses that triggered these cases aren't clear.

Slippery elm is generally well tolerated for short-term use, though high-quality safety data are limited. Both ingredients carry cautions in pregnancy and breastfeeding — safflower may stimulate the uterus and has been traditionally used to bring on menstruation, so medicinal amounts are not advised in pregnancy; slippery elm lacks reliable safety data for pregnancy or breastfeeding.

Topically, slippery elm pollen and extracts can cause contact dermatitis and urticaria in sensitive people.

Side effects, ingredient by ingredient Safflower Slippery Elm

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?
  • 2 of the 2 matched ingredients can interact with medications — Safflower, Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 2,069 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 using if you take blood thinners (anticoagulants), warfarin, or diabetes medications — safflower carries Moderate interactions with all three. Additionally, slippery elm may slow absorption of any oral medications you're on.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is best considered with your pharmacist's input, especially if you take blood thinners, warfarin, or diabetes drugs. The safflower component has documented interactions with those medications, and slippery elm may interfere with how your body absorbs other oral drugs.

If you're pregnant, planning to breastfeed, or have liver concerns, talk with your pharmacist before adding it.

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.

American Saffron & Slippery Elm by TerraVita: Common Questions

Does American Saffron & Slippery Elm by TerraVita interact with any medications?
Yes. Based on its ingredients, American Saffron & Slippery Elm has a known interaction with 2,068 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
American Saffron & Slippery Elm 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 on warfarin or a blood thinner?
Not without checking with your pharmacist first. The safflower in this product has a documented Moderate interaction with warfarin and other blood thinners — one case report shows a patient developed bleeding after adding safflower extract to warfarin. High doses especially carry extra risk. Run it by your pharmacist before you use it.
Will this affect my diabetes medication?
Possibly. The safflower component is flagged for a Moderate interaction with diabetes drugs. Some research suggests safflower oil can raise fasting blood sugar, which could work against your medication's job. Check with your pharmacist or doctor before adding this.
Could this slow down my other medications?
Yes, slippery elm may. Its mucilage can interfere with how your body absorbs oral drugs, potentially lowering their blood levels. If you take other medications by mouth, talk to your pharmacist about spacing or whether this product is right for you.
Is this safe during pregnancy?
The safflower component carries mixed safety ratings for pregnancy, and some are cautious. Safflower has been traditionally used to bring on menstruation, so medicinal amounts are not advised during pregnancy. Slippery elm also lacks reliable safety data for pregnancy. Talk with your doctor before using it if you're pregnant.
What are these ingredients actually used for?
Traditional herbalism uses safflower for heart and circulation issues and slippery elm for soothing the digestive tract and throat. However, the reliable evidence doesn't support clear claims for either ingredient — the data we hold shows insufficient evidence to rate them for any specific condition.
Is there any risk of liver problems from this?
Safflower oil has been linked in case reports to severe liver failure, usually from over-use for weight loss, though the exact triggering doses aren't clear. This product contains safflower extract, so it's worth knowing about this risk. Talk with your pharmacist about your liver health before starting.
