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: false unicorn root. It's a traditional herbal remedy historically used to support women's reproductive health, though clinical evidence for its effectiveness isn't established in our data.

The ingredient is enclosed in a capsule.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Glandular system support.
  • We looked for evidence on: Hormonal balance, Menstrual health, Endocrine function.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't hold effectiveness ratings for false unicorn in our data, so we can't tell you whether it works for any particular purpose based on clinical evidence.

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.

False unicorn is generally well tolerated by mouth, but large doses have been reported to cause nausea and vomiting. Safety data in humans is limited.

The safety data advises against use in pregnancy because of its traditional use to affect the uterus and lack of safety information. There isn't enough safety information for breastfeeding, so talk with your doctor or pharmacist about whether it's right for you if you're nursing.

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.

False Unicorn may be worth considering if you're interested in traditional herbal support for reproductive health, but it's important to check your medications first—it affects how your liver processes a large number of drugs.

Talk with your pharmacist about whether it's a good fit for you.

False Unicorn3 drug types · 740 drugs

Cytochrome P450 2D6 (Cyp2D6) Substrates

In vitro, false unicorn extract inhibits cytochrome P450 2D6 (CYP2D6) activity. Theoretically, false unicorn might increase the levels of CYP2D6 substrates.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

In vitro, false unicorn extract inhibits cytochrome P450 3A4 (CYP3A4) activity. Theoretically, false unicorn might increase the levels of CYP3A4 substrates. Drugs that might be affected include some calcium channel blockers (diltiazem, nicardipine, verapamil), chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), glucocorticoids, cisapride (Propulsid), alfentanil (Alfenta), fentanyl (Sublimaze), losartan (Cozaar), fluoxetine (Prozac), midazolam (Versed), omeprazole (Prilosec), ondansetron (Zofran), propranolol (Inderal), fexofenadine (Allegra), and numerous others.
