HelloPharmacist Scorecard of Restharrow 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.
What’s inside
Full disclosure
Restharrow Powder is a single-ingredient product containing restharrow in powder form. There are no inactive ingredients listed.
Does it work?
Insufficient evidence
The evidence we have doesn't yet establish whether restharrow works for benign prostatic hyperplasia (BPH), kidney stones, urinary tract infections, or gastritis. All four conditions show insufficient reliable evidence to rate its effectiveness.
How safe is it?
Some data gaps
Restharrow is traditionally used but human safety data are limited, so caution is warranted. The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.
Talk with your doctor or pharmacist for personalized guidance if you're pregnant, planning pregnancy, or nursing.
Meds to double-check
Moderate interaction found
If you take lithium, check with your pharmacist or doctor before using restharrow—the herb may theoretically raise lithium levels due to its potential diuretic effects.
The bottom line
Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.
Restharrow is a traditional herb with limited human safety and effectiveness data. If you take lithium, you'll need to check with your doctor before starting it.
Anyone pregnant, breastfeeding, or taking other medications should chat with us first.

HelloPharmacist Interaction Report
Restharrow Powder by TerraVita Premium Collection interacts with one medication type we have data for.
The main concern is lithium, a mood-stabilizing medication used for bipolar disorder. Restharrow is thought to have diuretic properties—meaning it may increase urine output.
Because of this, it could theoretically raise lithium levels in your blood, which might make side effects worse or become dangerous. We should note that diuretic activity hasn't actually been tested in people, so this is a theoretical risk based on how the herb works.
Read the full breakdown — every affected drug type, severity by severity
If you take lithium, don't start restharrow without talking to your doctor or pharmacist first. They may need to monitor your lithium levels more closely or adjust your dose.

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.
