HelloPharmacist Scorecard of Restharrow Chocolate Flavor 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

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: restharrow glycerite liquid extract, a liquid extract traditionally used to support urinary and kidney health. The remaining ingredients — glycerin and chocolate flavor — are inactive and used for taste and texture.

There are no fillers or binders in the active ingredient itself.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Spiny Restharrow's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: mild diuretic support for urinary tract health.
  • We looked for evidence on: Urinary tract infections (UTIs), Kidney stones (nephrolithiasis), fluid retention, urinary flow.
  • The closest evidence on file: Spiny Restharrow is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Spiny Restharrow is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs).

The evidence on restharrow doesn't yet support a clear rating for the conditions it's traditionally used for. Our data shows insufficient reliable evidence to rate it for benign prostatic hyperplasia (enlarged prostate), kidney stones, urinary tract infections, or gastritis.

That doesn't mean it doesn't work — it means the human studies needed to be confident aren't there yet.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Restharrow is generally regarded as traditionally used, but human safety data are limited. The product carries a caution for this reason.

It should be avoided in pregnancy and while breastfeeding, as safety information is either absent or not established. No adverse effects are documented in the data we hold, though that's partly because human studies on this ingredient are sparse.

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 — Spiny Restharrow.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 1 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.

If you take lithium, check with your pharmacist or doctor before using this product — restharrow may increase lithium levels (Moderate severity). No other interactions are documented for the ingredients we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

Restharrow has a long history of traditional use for urinary and kidney support, but modern evidence in humans is lacking. If you take lithium, you'll need to check with your pharmacist first.

Lithium

Theoretically, spiny restharrow might increase the levels and clinical effects of lithium.
Spiny restharrow is thought to have diuretic properties. Although animal studies suggest that spiny restharrow reduces edema, diuretic activity has not been reported or evaluated in humans. Theoretically, due to these potential diuretic effects, spiny restharrow might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Restharrow Chocolate Flavor by TerraVita: Common Questions

Does Restharrow Chocolate Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Restharrow Chocolate Flavor has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Restharrow Chocolate Flavor 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.
What does restharrow do?
Restharrow has been used traditionally to support urinary and kidney health. It's thought to have diuretic properties — meaning it may increase urination — but human studies confirming this haven't been done yet.
Does this product actually work?
The evidence isn't established in our data. We have insufficient reliable evidence to rate restharrow for benign prostatic hyperplasia, kidney stones, urinary tract infections, or gastritis. That doesn't mean it doesn't work — just that we need more human studies to be sure.
Is it safe to take while pregnant?
No. There isn't enough safety information, so the data advises against it in pregnancy. Talk with your doctor if you're pregnant and thinking about urinary or kidney support.
Can I take it while breastfeeding?
No. Safety while breastfeeding is unknown, so it's best avoided. If you're breastfeeding and want support for urinary or kidney health, ask your pharmacist about alternatives with more safety data.
What are the side effects?
No adverse effects are documented in our data. That said, human studies on restharrow are limited, so we may not have the full picture yet.
