Nettle root AND BPH

Hamid Reza Moradi, Naeem Erfani Majd, Saleh Esmaeilzadeh, Sayed Reza Fatemi Tabatabaei
Benign prostatic hyperplasia (BPH) is a common disease in human that gradual overgrowth of the prostate gland leads to impinge on the urethra with impairment in urinary function. Numerous plants improve uncontrolled growth of the prostate gland and improve urinary tract symptoms associated with BPH. In this study, 25 healthy adult male Wistar rats were divided randomly in five groups: G1 (Control group) received ordinary feed without any treatment, G2 received 10 mg kg(-1) testosterone subcutaneously, G3 received 50 mg kg(-1) nettle root extract orally, G4 received 50 mg kg(-1) nettle root extract orally and 10 mg kg(-1) testosterone, G5 received 10 mg kg(-1) almond oil (Almond oil was used as testosterone solvent) subcutaneously...

PURPOSE: To determine the effects of the herbal fixed-dose combination PRO 160/120 (extracts from saw palmetto fruits and stinging nettle roots) on nocturnal voiding frequency, as measured by question 7 of the IPSS questionnaire, in patients with moderate-to-severe LUTS/BPH after 24 weeks of treatment compared to placebo, to the α-blocker tamsulosin, or to the 5α-reductase inhibitor finasteride. METHODS: The study is about post hoc evaluation of four published randomized, double-blind clinical trials on PRO 160/120, two compared with placebo, one with finasteride and one with tamsulosin...

Nettle root is recommended for complaints associated with benign prostatic hyperplasia (BPH). We therefore conducted a comprehensive review of the literature to summarise the pharmacological and clinical effects of this plant material. Only a few components of the active principle have been identified and the mechanism of action is still unclear. It seems likely that sex hormone binding globulin (SHBG), aromatase, epidermal growth factor and prostate steroid membrane receptors are involved in the anti-prostatic effect, but less likely that 5alpha-reductase or androgen receptors are involved...

With benign prostatic hyperplasia (BPH) being a major health problem in ageing men, alternative therapeutic approaches (e.g., with phytopharmaceuticals) are of great interest. Based on pharmacological evidences, one of the most promising options in that respect are the lectins found in Urtica dioica (stinging nettle) roots. In this study the qualitative and quantitative analysis of individual isolectins in U. dioica extracts is described, which is the first report on using capillary electrophoresis (CE) for the analysis of lectins in plant material at all...

Symptomatic benign prostatic hyperplasia (BPH), which a man has a 50% chance of developing during the course of his lifetime, should receive stage-related treatment. While Vahlensieck stage I disease requires no therapy, stages II and III are indications for medication. Established medications for the treatment of BPH in current use are alpha-blockers, finasteride, and the phytotherapeutic agents pumpkin seed (cucurbitae semen), nettle root (urticae radix), the phytosterols contained in Hypoxis rooperi, rye pollen and the fruits of saw palmetto (sabalis serrulati fructus)...

Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) are very common disorders in aging men. Despite the great clinical importance, many aspects of their aetiology remain uncertain although it is generally accepted that advanced age and testicular androgens are important requirements for the development of these complaints. The currently available therapeutic options include watchful waiting, changes of life style, medical treatments and invasive therapies. In many European countries the use of phytopharmaceuticals for the management of BPH and related LUTS is common and these products represent up to 80 % of all drugs prescribed for this disorder...

OBJECTIVE: To test the hypothesis that in patients with benign prostatic hyperplasia (BPH), the outcome of drug therapy with finasteride may be predictable from the baseline prostate volume and that positive clinical effects might be expected only in patients with prostate volumes of > 40 mL, using a subgroup analysis of results from a previously reported clinical trial of finasteride and phytotherapy. PATIENTS AND METHODS: A subgroup of 431 patients was analysed from a randomized, multicentre, double-blind clinical trial involving 543 patients with the early stages of BPH...

In Germany, plant extracts are often used in the treatment of early stages of benign prostate hyperplasia (BPH). The effects of different concentrations of the polysaccharide fraction of the 20% methanolic extract of stinging nettle roots (POLY-M) on the cellular proliferation of lymph node carcinoma of the prostate (LNCaP) cells were determined by measurement of the genomic DNA content of the samples. All concentrations of POLY-M showed an inhibitory effect on the growth of the LNCaP cells during 7 days except the two lowest concentrations...

Polar extracts of the stinging nettle (Urtica dioica L.) roots contain the ligans (+)-neoolivil, (-)-secoisolariciresinol, dehydrodiconiferyl alcohol, isolariciresinol, pinoresinol, and 3,4-divanillyltetrahydrofuran. These compounds were either isolated from Urtica roots, or obtained semisynthetically. Their affinity to human sex hormone binding globulin (SHBG) was tested in an in vitro assay. In addition, the main intestinal transformation products of plant lignans in humans, enterodiol and enterolactone, together with enterofuran were checked for their activity...

Extracts of stinging nettle roots (Urtica dioica L. Urticaceae) are used in the treatment of benign prostatic hyperplasia (BPH). We established a BPH-model by directly implanting an urogenital sinus (UGS) into the ventral prostate gland of an adult mouse. Five differently prepared stinging nettle root extracts were tested in this model. The 20% methanolic extract was the most effective with a 51.4% inhibition of induced growth.

Phytotherapeutic preparations are still commonly used for the treatment of symptomatic benign prostate hyperplasia (BPH) in Germany; in recent years there has even been an increase in their use, so that sales now amount to more than DM 220 millions per year. The preparations most frequently used are extracts of Hypoxis rooperi, the roots of the stinging nettle, the fruits of the saw palmetto, pumpkin seeds and rye pollen. The suggested mechanisms of action have not been documented by scientific observation...

The effects of organic-solvent extracts of Urtica dioica (Urticaceae) on the Na+,K(+)-ATPase of the tissue of benign prostatic hyperplasia (BPH) were investigated. The membrane Na+,K(+)-ATPase fraction was prepared from a patient with BPH by a differential centrifugation of the tissue homogenate. The enzyme activity was inhibited by 10(-4)-10(-5) M of ouabain. The hexane extract, the ether extract, the ethyl acetate extract, and the butanol extract of the roots caused 27.6-81.5% inhibition of the enzyme activity at 0...
