HelloPharmacist Scorecard of Rue 4:1 Extract 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 a single active ingredient: rue extract in powder form, concentrated as a 4:1 extract (meaning four parts of the herb are reduced to one part extract). There are no 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 Rue product and its label doesn't state a use — see Rue'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 isn't established in our data for what rue is commonly used for — including abortion, cancer, contraception, dyspepsia (indigestion), or insect repellent. All of those uses are rated insufficient reliable evidence to rate.

That doesn't mean rue doesn't work; it means the trials and studies we hold don't support those claims yet.

The evidence, ingredient by ingredient Rue

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.

Rue in the dried medicinal form is generally well tolerated, though a thorough safety review hasn't been done. The fresh herb is considered unsafe.

At higher doses, rue can cause cramps, drowsiness, dizziness, gastrointestinal irritation, sleep disturbances, and in very high doses, respiratory distress. It can also trigger contact dermatitis and phototoxic skin reactions when applied topically or taken orally in the presence of sunlight.

Rue has a history of being used to bring on menstruation or abortion and may harm a pregnancy — it's rated likely unsafe in pregnancy. Breastfeeding safety data isn't on file.

The oil form is especially risky and should be avoided.

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 — Rue.
  • The most serious interaction on file is rated Moderate.
  • For scale: 335 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.

Photosensitizing drugs — medications that make your skin reactive to sun — pose a Moderate risk when combined with rue. If you take any drug that increases light sensitivity, check with your pharmacist before starting this product.

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.

Rue is not well studied for the conditions people typically use it for, and it carries real risks — particularly phototoxicity and pregnancy harm. If you're pregnant, breastfeeding, or taking a photosensitizing medication, this isn't for you.

Anyone else should talk to their pharmacist first, especially if you're on any prescription.

Rue 4:1 Extract Powder by TerraVita Premium Collection: Common Questions

Does Rue 4:1 Extract Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Rue 4:1 Extract Powder has a known interaction with 335 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Rue 4:1 Extract 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.
Can I take this if I'm pregnant?
No. Rue is rated likely unsafe in pregnancy because it's been used traditionally to bring on miscarriage and may harm your baby. It should be avoided.
Is rue safe to take while breastfeeding?
Safety data isn't on file for breastfeeding, and potentially toxic compounds may pass to your baby, so it should be avoided. Talk to your pharmacist or doctor for personalized advice.
What's the most common side effect I might feel?
The dried herb can cause cramps, drowsiness, dizziness, gastrointestinal irritation, and sleep disturbances. Fresh rue is considered unsafe and carries a higher risk of problems.
Does this powder actually work for what it's marketed for?
The evidence we hold doesn't support reliable claims for rue's use in abortion, cancer, contraception, indigestion, or insect repellent — all are rated insufficient evidence to rate. That doesn't mean it's ineffective, just that studies haven't proven it yet.
What's a 4:1 extract?
That means the manufacturer started with four parts of the raw rue herb and concentrated it down to one part powder. It's a way to make the herb more concentrated.
I'm on a sunscreen or a drug that makes me sun-sensitive. Can I take this?
Check with your pharmacist first. Rue contains compounds that cause phototoxic reactions on their own, and mixing it with photosensitizing drugs may increase that risk further.
