Swelling of the prostate gland causes a range of lower urinary tract symptoms including weak urinary stream, in complete voiding resulting in left over urine; a risk for urinary tract infection and prostatitis, a constant urge to urinate, and sleep disturbance due to multiple trips to the bathroom at night.
In this study the effects of Stinging Nettle (Urtica Dioica) on prostate health was compared to placebo in 620 men. It was a 6-month, double-blind, placebo-controlled, randomized study; the ?gold standard? of studies.
The patients were evaluated using the International Prostate Symptom Score (IPSS), the maximum urinary flow rate (Qmax), post void residual urine volume (PVR), PSA, testosterone levels, and prostate size.
At the end of 6-months all men were switched to Stinging Nettles for an additional year (an 18 month total trial). At the end of 6-months 81% of the patients on Stinging Nettle reported improved lower urinary tract symptoms compared to only 16% in the placebo group (the mind and circumstance always has some positive effect). The IPSS had a significant improvement with supplementation where placebo had little effect. Qmax also improved more on the herb. PVR had a good drop in the Nettle group with no effect in placebo. Neither group had a change in testosterone or PSA level. Transrectal sonography showed that there was a modest shrinkage in the size of the prostate in the men on Stinging Nettle with no shrinkage in size in the men on placebo. The Nettle and the placebo caused no side effects. The study is published in the Journal of Herbal Pharmacotherapy, 2005;5(4).
A combination of Saw Palmetto Berry with Stinging Nettle Root effectively treats lower urinary tract symptoms caused by a swollen prostate (BPH) in elderly men
A combination of Saw Palmetto Berry and Stinging Nettle Root was compared to placebo in 257 elderly men with lower urinary tract symptoms caused by swelling of their prostate gland for 24 weeks in a randomized, double-blinded, placebo-controlled study. At the end of the six-month period all men were placed on the herbs for an additional six-months.
The IPSS improved substantially on herbs compared to placebo. This improvement applied to obstructive symptoms such as poor urinary flow, as well as irritating symptoms such as the feeling of urgency to void. The improvement also applied both to men with moderate or severe symptoms. When men were changed from placebo to herb they also experienced an improvement in urinary tract symptoms. The herbs were free of side effects. The study is published in the June 2005 issue of the World Journal of Urology.
Saw Palmetto Berries compared to the benefits of tamsulosin (Flomax in the USA) for urinary tract symptoms caused by a swollen prostate
In this study the effects of Saw Palmetto Berry were compared to those of tamsulosin (Flomax) in men with lower urinary tract symptoms caused by BPH (a swollen prostate). The effects of the combination of the herb with the drug were also evaluated. The effects of the herb and drug were statistically the same for improving Qmax (maximal urinary flow rate) and IPSS (International Prostate Symptom Score). The Saw Palmetto Berries caused no adverse effects. Adding Saw Palmetto and tamsulosin together did not seem to improve the benefits from either agent. The study is published in the January 4th, 2007 issue of the journal International Urology and Nephrology.
