HelloPharmacist Scorecard of Prostate Health by Herb Pharm

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

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 5 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (648 mg) without saying how much of each component you get.

This liquid contains 5 active ingredients, each extracted from plants. Saw Palmetto berry is the main one; Stinging Nettle Root, Pipsissewa, Cleavers, and Thuja Branchlet make up a proprietary blend.

The liquid base includes cane alcohol, distilled water, and glycerin as inactive ingredients to carry the extracts.

Does it work?

Leans against
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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: Prostate health and reproductive system support.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Non-neurogenic lower urinary tract symptoms (LUTS), Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, Urinary tract infections (UTIs), Urinary flow — and 1 related terms.
  • The closest evidence on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Stinging Nettle is rated "Insufficient Reliable Evidence To Rate" for Benign prostatic hyperplasia (BPH), Urinary tract infections (UTIs).
  • Also on file: Saw Palmetto is rated "Insufficient Reliable Evidence To Rate" for Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, Non-neurogenic lower urinary tract symptoms (LUTS).

The evidence for these ingredients in prostate health is mixed. Saw Palmetto has possibly ineffective evidence for benign prostatic hyperplasia (enlarged prostate), though it is possibly effective for transurethral resection of the prostate (a specific urological procedure).

Stinging Nettle Root shows possibly effective evidence for diabetes but insufficient evidence for benign prostatic hyperplasia. For the other ingredients — Cleavers, Pipsissewa, and Thuja — we hold insufficient or no reliable evidence to rate their effectiveness.

The evidence, ingredient by ingredient Saw Palmetto Pipsissewa Stinging Nettle Thuja

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Saw Palmetto is generally well tolerated, though mild side effects include abdominal pain, constipation, diarrhea, headache, nausea, and fatigue. Rare cases of heart rhythm changes and skin reactions have been reported.

Stinging Nettle Root is generally well tolerated for most adults; the most common side effects are constipation and diarrhea. Thuja contains thujone, a compound that can be toxic in large doses — symptoms of toxicity include headache, nervousness, seizures, vomiting, abdominal pain, and diarrhea.

Saw Palmetto and Stinging Nettle are likely unsafe in pregnancy; Thuja is also likely unsafe in pregnancy and while breastfeeding. Cleavers and Pipsissewa should be avoided in pregnancy due to insufficient safety data, and safety while breastfeeding has not been established for any of these ingredients.

Thuja Branchlet Extract, Fresh, Undried3 drug types · 576 drugs

Anticonvulsants

Thuja products can contain thujone, which might lower the seizure threshold. Theoretically, this could decrease the effectiveness of anticonvulsants drugs.

Likelihood Possible Evidence D
Immunosuppressants

Thuja might stimulate immune function. Theoretically, taking thuja might decrease the effects of immunosuppressive therapy. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), and other corticosteroids (glucocorticoids).

Likelihood Possible Evidence D
Seizure Threshold Lowering Drugs

Thuja products can contains significant amounts of thujone, a neurotoxin. Theoretically, patients taking drugs that lower the seizure threshold might be at greater risk of seizure if they also take thuja. Advise patients taking these drugs to avoid thuja products. Some drugs that lower the seizure threshold include anesthetics (propofol, others), antiarrhythmics (mexiletine), antibiotics (amphotericin, penicillin, cephalosporins, imipenem), antidepressants (bupropion, others), antihistamines (cyproheptadine, others), immunosuppressants (cyclosporine), narcotics (fentanyl, others), stimulants (methylphenidate), theophylline, and others.

Likelihood Possible Evidence D

Saw Palmetto berry extract3 drug types · 174 drugs

Anticoagulant/Antiplatelet Drugs

Saw palmetto might increase the risk of bleeding with anticoagulant or antiplatelet drugs.
Saw palmetto is reported to prolong bleeding time. Theoretically, it might increase the risk of bleeding when used concomitantly with anticoagulant or antiplatelet drugs.

Likelihood Possible Evidence D
Contraceptive Drugs

Saw palmetto might reduce the effectiveness of contraceptive drugs.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with contraceptive drugs taken concomitantly.

Likelihood Possible Evidence B
Estrogens

Saw palmetto might reduce the effectiveness of estrogens.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with estrogens taken concomitantly.

Likelihood Possible Evidence B

Stinging Nettle Root Extract, Fresh, Undried4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Prostate Health by Herb Pharm: Common Questions

Does Prostate Health by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Prostate Health has a known interaction with 879 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Prostate Health contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Is this safe if I'm pregnant or breastfeeding?
No. Saw Palmetto is likely unsafe in pregnancy, and Stinging Nettle and Thuja are also likely unsafe during pregnancy. For breastfeeding, safety hasn't been established for any of these ingredients, so it's best to avoid it. Talk with your doctor or pharmacist for personalized advice.
What are the most common side effects?
Saw Palmetto most often causes mild effects like abdominal pain, constipation, diarrhea, headache, nausea, and fatigue. Stinging Nettle mainly causes constipation or diarrhea. These are usually reversible.
Does this actually work for prostate health?
Saw Palmetto shows possibly ineffective evidence for benign prostatic hyperplasia (enlarged prostate), so the evidence is weak. Stinging Nettle has insufficient evidence for prostate health. The other ingredients lack reliable evidence data.
Why does this contain Thuja if it can be toxic?
Thuja is toxic in large doses, but this product is a diluted extract. Still, you should avoid it if you take seizure medications, anticonvulsants, or immunosuppressants, since it interacts with those drug types.
What is Stinging Nettle Root supposed to do in this blend?
Stinging Nettle Root is traditionally used for urinary and prostate support. The facts show possibly effective evidence for diabetes but only insufficient evidence for prostate health specifically.
Can I take this with my blood thinner?
Not without checking with your pharmacist first. Saw Palmetto may increase bleeding risk with blood thinners like warfarin, and Stinging Nettle contains vitamin K, which can interfere with warfarin. Use the medication checker on this page.
