HelloPharmacist Scorecard of Blessed Thistle & Fenugreek 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

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.
  • “Blessed Thistle & Fenugreek 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 product contains 2 active ingredients: Blessed Thistle Glycerite Liquid Extract and Fenugreek Glycerite Liquid Extract, both delivered in a glycerin base. Blessed thistle is traditionally used to support digestive health, while fenugreek seed has been used to help with blood sugar balance and sexual function.

The glycerin base is an inactive ingredient that keeps the herbs in liquid form.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Sexual dysfunction — rated "Possibly Effective" (Fenugreek) (Natural Medicines).
  • On file: Diabetes — rated "Possibly Effective" (Fenugreek) (Natural Medicines).
  • On file: Sexual arousal — rated "Possibly Effective" (Fenugreek) (Natural Medicines).
  • On file: Dysmenorrhea — rated "Possibly Effective" (Fenugreek) (Natural Medicines).

Blessed thistle has insufficient reliable evidence to rate it for dyspepsia (indigestion). Fenugreek seed, on the other hand, is possibly effective for sexual dysfunction, sexual arousal, dysmenorrhea (period pain), and diabetes—clinical research does show fenugreek can lower fasting blood sugar in people with type 2 diabetes, though the evidence for sexual benefits is more limited.

The evidence, ingredient by ingredient Blessed Thistle Fenugreek

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.

Blessed thistle is often well tolerated in small amounts, but human safety data are limited. High doses (more than 5 grams per cup of tea) can cause stomach irritation, nausea, and vomiting.

It may cause allergic reactions in people sensitive to the ragweed and daisy family. Fenugreek is generally well tolerated in food amounts but may cause abdominal pain, bloating, diarrhea, indigestion, flatulence, low blood sugar (hypoglycemia), or nausea at supplement doses.

Rare severe allergic reactions including swelling, difficulty breathing, and shock have been reported. Both ingredients are rated likely unsafe in pregnancy.

Blessed thistle lacks safety data in breastfeeding and should be checked with your provider first, while fenugreek is possibly safe for breastfeeding but is traditionally used to support milk supply—discuss with your doctor before using it for that purpose.

Side effects, ingredient by ingredient Blessed Thistle Fenugreek

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 — Blessed Thistle, Fenugreek.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 417 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 with us before using this product if you take blood thinners or antiplatelet drugs like warfarin or clopidogrel (moderate risk), diabetes medications (moderate risk), theophylline for breathing (moderate risk), metoprolol for blood pressure (moderate risk), phenytoin for seizures (moderate risk), sildenafil for erectile dysfunction (moderate risk), or acid-reducing medications like H2-blockers, antacids, or PPIs (minor risk).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood thinners, diabetes medications, or heart and breathing drugs, check your exact medications with us before starting this product. The two herbs here aren't for everyone, especially if you're pregnant, taking acid-reducing drugs, or managing blood sugar or bleeding risk.

Talk to your pharmacist or doctor about whether either ingredient is right for you.

Blessed Thistle & Fenugreek by TerraVita: Common Questions

Does Blessed Thistle & Fenugreek by TerraVita interact with any medications?
Yes. Based on its ingredients, Blessed Thistle & Fenugreek has a known interaction with 417 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Blessed Thistle & Fenugreek 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?
No. Both blessed thistle and fenugreek are rated likely unsafe during pregnancy. If you're pregnant or planning to become pregnant, skip this product and talk to your doctor about what's right for you.
Is it okay to use while breastfeeding?
Fenugreek is possibly safe for breastfeeding and is traditionally used to support milk supply, but safety hasn't been well studied—talk with your doctor first. Blessed thistle lacks safety data for breastfeeding, so check with your provider before using it.
What are the most common side effects?
Fenugreek may cause abdominal pain, bloating, diarrhea, indigestion, gas, nausea, or low blood sugar. Blessed thistle in high doses can cause stomach irritation and vomiting. Both can trigger allergic reactions in people sensitive to ragweed or daisy-family plants.
Does this actually work for sexual dysfunction?
Fenugreek is rated possibly effective for sexual dysfunction and sexual arousal, meaning there's some clinical evidence but it's not definitive. Blessed thistle doesn't have enough evidence to rate for this use.
Can it help with diabetes?
Fenugreek is rated possibly effective for diabetes—clinical research shows it can lower fasting blood sugar in people with type 2 diabetes. However, it can also lower blood sugar further when combined with diabetes medications, so you'd need to check your exact drugs with your pharmacist.
Why does the interaction count say 414 medications?
Fenugreek interacts with several categories of drugs—blood thinners, diabetes medications, heart and breathing drugs, and others—and each category includes many different individual medications. The 414 is the total deduplicated count across all of fenugreek's interactions combined.
