    PubMed ID: 7509261

    Fixed combination (nettle root + Pygeum) showed urinary symptom improvements; supports urinary benefit but attribution to nettle alone is uncertain.

  3. Combined sabal and urtica extract compared with finasteride in men with benign prostatic hyperplasia: analysis of prostate volume and therapeutic outcome

    PubMed ID: 10971268

    Large trial of saw palmetto + nettle performed similarly to finasteride for BPH symptoms—supports symptomatic urinary benefit within a combination product.

  4. [Stinging nettle root extract (Bazoton-uno) in long term treatment of benign prostatic syndrome (BPS). Results of a randomized, double-blind, placebo controlled multicenter study after 12 months]

    PubMed ID: 15045190

    12-month randomized trial of nettle root extract alone with statistically significant IPSS improvement—good long-term clinical evidence for urinary symptom relief.

  5. Long-term efficacy and safety of a combination of sabal and urtica extract for lower urinary tract symptoms--a placebo-controlled, double-blind, multicenter trial

    PubMed ID: 15928959

    Multicenter RCT of sabal+urtica demonstrating clinically meaningful I-PSS improvement vs placebo—supports benefit though nettle was combined with saw palmetto.

  6. Urtica dioica for treatment of benign prostatic hyperplasia: a prospective, randomized, double-blind, placebo-controlled, crossover study

    PubMed ID: 16635963

    Large RCT of nettle root showing substantial, objective improvements in IPSS, Qmax and postvoid residual—strong direct evidence for urinary symptom benefit.

  7. [Efficacy of a combined Sabal-urtica preparation in the symptomatic treatment of benign prostatic hyperplasia. Results of a placebo-controlled double-blind study]

    PubMed ID: 16261945

    Re-analysis showing PRO160/120 (sabal+urtica) reduced urgency/frequency and improved QoL—supports urinary symptom relief within combination.

  8. [Combined extract of Sabal palm and nettle in the treatment of patients with lower urinary tract symptoms in double blind, placebo-controlled trial]

    PubMed ID: 16708583

    Double-blind trial of saw palmetto + nettle showing LUTS improvement and good tolerability—combination evidence supports urinary comfort.

  9. Efficacy and safety of a combination of Sabal and Urtica extract in lower urinary tract symptoms--long-term follow-up of a placebo-controlled, double-blind, multicenter trial

    PubMed ID: 18038253

    Large trial showing clinically meaningful improvements in prostate/urinary symptoms with a fixed saw palmetto + nettle combination; nettle-specific contribution uncertain but benefits apply to urinary comfort.

  10. Fixed-dose combination PRO 160/120 of sabal and urtica extracts improves nocturia in men with LUTS suggestive of BPH: re-evaluation of four controlled clinical studies

    PubMed ID: 24938176

    Pooled analysis of saw palmetto + nettle combo showed reduced nocturia vs placebo; meaningful urinary comfort effect though combination product limits nettle attribution.

  11. Urtica Dioica Root Extract on Clinical and Biochemical Parameters in Patients with Benign Prostatic Hyperplasia, Randomized Controlled Trial

    PubMed ID: 32981268

    Randomized trial of Urtica dioica root extract improved IPSS and urinary symptoms — direct nettle root evidence for urinary benefit.

Inflammation (3)
  1. A Rosa canina - Urtica dioica - Harpagophytum procumbens/zeyheri Combination Significantly Reduces Gonarthritis Symptoms in a Randomized, Placebo-Controlled Double-Blind Study

    PubMed ID: 28614869

    Rosehip/nettle/devil's-claw formulation reduced OA pain and improved function—consistent with anti-inflammatory/analgesic effects within a combination product.

  2. Phytalgic, a food supplement, vs placebo in patients with osteoarthritis of the knee or hip: a randomised double-blind placebo-controlled clinical trial

    PubMed ID: 20015358

    Nutraceutical containing nettle reduced NSAID use and improved OA symptoms, implying anti-inflammatory/analgesic benefit for the formulation.

  3. The effect of hydro alcoholic Nettle (Urtica dioica) extracts on insulin sensitivity and some inflammatory indicators in patients with type 2 diabetes: a randomized double-blind control trial

    PubMed ID: 22303583

    Randomized trial showed reductions in IL‑6 and hs‑CRP in diabetics after nettle extract, supporting anti‑inflammatory activity.

Joint comfort (2)

    PubMed ID: 28614869

    12-week double-blind RCT of a rosehip/nettle/devil's-claw formulation showed reduced knee OA pain and improved function versus placebo—supports symptom relief within a combination.

  2. Phytalgic, a food supplement, vs placebo in patients with osteoarthritis of the knee or hip: a randomised double-blind placebo-controlled clinical trial

    PubMed ID: 20015358

    Three-month randomized DBRCT of a nutraceutical (fish oils, nettle, zinc, vit E) reduced analgesic/NSAID use and improved WOMAC scores in OA—benefit shown for the multi-ingredient product including nettle.

Blood sugar (2)
  1. Improved glycemic control in patients with advanced type 2 diabetes mellitus taking Urtica dioica leaf extract: a randomized double-blind placebo-controlled clinical trial

    PubMed ID: 24273930

    Randomized double-blind placebo-controlled trial of nettle leaf extract in insulin-treated T2DM showing significant reductions in fasting glucose, postprandial glucose and HbA1c—strong direct evidence.

    PubMed ID: 29228792

    Randomized DBRCT showing improved fasting glucose and HbA1c but used a fixed combination (silymarin, frankincense, nettle), so effect cannot be attributed solely to nettle.
