Nearly 25% of U.S. adults report concurrently taking a prescription medication with a dietary supplement. Some supplements, such as St. John's wort and goldenseal, are known to cause clinically important drug interactions and should be avoided by most patients receiving any pharmacologic therapy. However, many other supplements are predicted to cause interactions based only on in vitro studies that have not been confirmed or have been refuted in human clinical trials. Some supplements may cause interactions with a few medications but are likely to be safe with other medications (e...

There is rising evidence of patients' use of alternative and complementary medicine. The percentage of the U.S. population who used at least one dietary supplement increased from 42% in 1988-1994 to 53% in 2003-2006. We present a case of an Asian female in her 40s, with no previous psychiatric illness, who presented to the emergency room following a brief psychotic episode, during which she self-amputated the tips of her fingers, after using multivitamins and herbal supplements including ginseng, gui yuan rou (Chinese herb), astaxanthin, goji (Chinese fruit), selenium, saw palmetto, grape seed extract, citrus bioflavanoid, lutein (zeaxantin), resvexatrol, sun chlorella, spirulina powder, phytoceramides, phytoestrogen, glucosatrin, bromelain plus, and American bee pollen...

OBJECTIVES: Benign prostatic hyperplasia (BPH) commonly affects men above 40 years old. The progression of BPH is often accompanied with lower urinary tract symptoms (LUTS) that can significantly affect the quality of life of the patients. Serenoa repens (saw palmetto) is a popular herbal remedy indicated for LUTS/BPH. We reviewed the current research on the efficacy of S. repens on LUTS/BPH as a monotherapy as well as combination therapies. DESIGN: Non-systematic searches were performed in PubMed for human studies and systematic reviews on the topic...

OBJECTIVES: Lower urinary tract symptoms (LUTS) and sexual dysfunction (SDys) are common problems that affect quality of life (QOL) in elderly men. In addition to prescribed drugs, many over-the-counter medications including supplements are used to treat QOL diseases. Phosphodiesterase inhibitors are reported to be effective for both LUTS and SDys by increasing nitric oxide levels. French maritime pine bark extract Pycnogenol(®), which is a potent nitric oxide donor, is reported to be effective for SDys...

For the first time, we discovered a small proportion of aqueous fraction from Saw Palmetto apart from the fatty acid-rich fraction exhibited pharmacological activity. Therefore, this study aims to explore the anti-tumor potential of red pigmented aqueous fraction of Saw Palmetto, NYG on human hepatocellular carcinoma and its possible targets. Subcutaneous xenograft and orthotopic implantation models of HCC were used to evaluate the tumor inhibitory effect of NYG. Human hepatocellular carcinoma (HCC) cell lines and human umbilical vein endothelial cells (HUVEC) were used as in vitro model...

Saw palmetto supplements (SPS) are commonly consumed by men with prostate cancer. We investigated whether SPS fatty acids and phytosterols concentrations determine their growth-inhibitory action in androgen-sensitive LNCaP cells and hamster flank organs. High long-chain fatty acids-low phytosterols (HLLP) SPS ≥ 750 nM with testosterone significantly increased and ≥500 nM with dihydrotestosterone significantly decreased LNCaP cell number. High long-chain fatty acids-high phytosterols (HLHP) SPS ≥ 500 nM with dihydrotestosterone and high medium-chain fatty acids-low phytosterols (HMLP) SPS ≥ 750 nM or with androgens significantly decreased LNCaP cell number (n = 3; p < 0...

BACKGROUND: The nicotinamide adenine dinucleotide phosphate-dependent membrane protein 5α-reductase catalyses the conversion of testosterone to the most potent androgen - 5α-dihydrotestosterone. Two 5α-reductase isoenzymes are expressed in humans: type I and type II. The latter is found primarily in prostate tissue. Saw palmetto extract (SPE) has been used extensively in the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH). The pharmacological effects of SPE include the inhibition of 5α-reductase, as well as anti-inflammatory and antiproliferative effects...

A simplified sample preparation method in combination with gas chromatography-triple-quadrupole mass spectrometry (GC-MS/MS) analysis was developed and validated for the simultaneous determination of 227 pesticides in green tea, ginseng, gingko leaves, saw palmetto, spearmint, and black pepper samples. The botanical samples were hydrated with water and extracted with acetonitrile, magnesium sulfate, and sodium chloride. The acetonitrile extract was cleaned up using solid phase extraction with carbon-coated alumina/primary-secondary amine with or without C18...

BACKGROUND: Patients who undergo surgery appear to use dietary supplements significantly more frequently than the general population. Because they contain pharmacologically active compounds, dietary supplements may affect coagulation and platelet function during the perioperative period through direct effects, pharmacodynamic interactions, and pharmacokinetic interactions. However, in this regard, limited studies have been conducted that address the pharmacological interactions of dietary supplements...

Saw palmetto fruit extract (SPE), as a herbal product, is widely used for the treatment of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Recent studies show that SPE also has some therapeutic effects on chronic prostatitis, prostate cancer, sexual dysfunction, and so on. This article presents an overview on the application of SPE in the treatment of BPH, prostate cancer, and chronic prostatitis/chronic pelvic pain syndrome, with a discussion on its action mechanisms.

The aim of this registry was to evaluate the management of initial symptoms of benign prostatic hyperthrophy (BPH) in otherwise healthy subjects, using Prostaquil® (Alchem) in a 8-week registry. Prostaquil was used at the dosage of 200 mg/day. The product includes Pygeum extract (100 mg) and Saw palmetto oil (35 mg). The two resulting groups standard management and supplement) were comparable. RESULTS: No side effects or comparability problems were observed and compliance was optimal with more than 95% of the capsules correctly used...

Serenoa repens, commonly known as saw palmetto, is the sole species currently classified in the genus Serenoa. The plant is a low shrubby palm that is native of West Indies, and it grows in the coastal lands of North America and other European mediterranean countries. Its fruits contain high concentrations of fatty acids and phytosterols. S. repens extracts have been studied for the symptomatic treatment of benign prostatic hyperplasia. Recently, they have been proposed to treat androgenic alopecia and other hair disorders...

COMPARATIVE STUDY

Prostatic inflammation is widespread in the male population. Two groups of 50 patients each with symptoms of prostatic inflammation and ecocolorDoppler indicative of prostatitis were identified. Both groups were further subdivided into two subgroups (respectively A1, A2, B1, and B2). Group A1 underwent therapy with oral levofloxacin 500 mg daily for 10 days plus co-treatment with oral Serenoa repens (320 mg) plus Bromeline plus Nettle (Prostamev Plus®) daily for two months; Group A2 with oral levofloxacin 500 mg daily for 10 days plus oral Serenoa repens extract 320 mg/day for two months; Group B1 specific antibiotic treatment for 10 days (included levofloxacin if sensitive) plus co-treatment with oral Serenoa repens (320 mg) plus Bromeline plus Nettle (Prostamev Plus®) daily for two months; Group B2 with specific antibiotic treatment for 10 days plus Serenoa repens 320 mg/day for two months...

β-Sitosterol is the most abundant plant sterol in the human diet. It is also the major component of several traditional medicines, including saw palmetto and devil's claw. Although β-sitosterol is effective against enlarged prostate in human clinical trials and has anti-cancer and anti-inflammatory activities, the mechanisms of action are poorly understood. Here, we report the identification of two new binding proteins for β-sitosterol that may underlie its beneficial effects.

Preparations containing Saw palmetto extracts are used in traditional medicine to treat benign prostatic hyperplasia. According to the European and the American Pharmacopoeias, the extract is obtained from comminuted Saw palmetto berries by a suitable extracting procedure using ethanol or supercritical carbon dioxide or a mixture of n-hexane and methylpentanes. In the present study an approach to metabolomics profiling using nuclear magnetic resonance (NMR) has been used as a finger-printing tool to assess the overall composition of the extracts...
