Why It Works

Ginsenosides modulate HPA axis and nitric oxide.

How it works in more detail

Ginsenosides, the triterpene saponins found in Panax ginseng, are thought to be responsible for most of its biological activities. Different ginsenosides (e.g., Rb1, Rg1, Re, Rd) have distinct pharmacological effects. They may modulate neurotransmitter release, influence nitric oxide synthesis, exhibit antioxidant properties, and affect inflammatory pathways. These actions collectively contribute to its potential adaptogenic, neuroprotective, immunomodulatory, and anti-fatigue effects. The exact and complete mechanisms are still under investigation.

  • Dietary Supplements for Erectile Dysfunction: Analysis of Marketed Products, Systematic Review, Meta-Analysis and Rational Use.

    Petre GC, Francini-Pesenti F, Vitagliano A, Grande G, Ferlin A, Garolla A · Nutrients · 2023

    The use of nutraceutical products to enhance male sexual performance has a long history, especially with regard to the treatment of erectile dysfunction (ED). Alternative treatments for ED are becoming increasingly popular, with growing interest from consumers, as well as increased revenue for manufacturers. Dietary supplements (DSs), which are a mixture of active ingredients, are mainly sold online. In randomized controlled trials, the molecules contained in DSs have demonstrated varying degrees of effectiveness, or even have no evidence to support their use. However, none of the studies carried out provided sufficient evidence to consider these products a first-line therapy. Therefore, the combination of the various active ingredients, especially in relation to the daily dose, leaves doubts about the real effectiveness. In order to evaluate the potential efficacy of DS formulations, we analyzed the products marketed in Italy using a scoring approach. A systematic review of the litera

  • Plant Adaptogens-History and Future Perspectives.

    Todorova V, Ivanov K, Delattre C, Nalbantova V, Karcheva-Bahchevanska D, Ivanova S · Nutrients · 2021

    Adaptogens are synthetic compounds (bromantane, levamisole, aphobazole, bemethyl, etc.) or plant extracts that have the ability to enhance the body's stability against physical loads without increasing oxygen consumption. Extracts from Panax ginseng, Eleutherococcus senticosus, Rhaponticum carthamoides, Rhodiola rosea, and Schisandra chinensis are considered to be naturally occurring adaptogens and, in particular, plant adaptogens. The aim of this study is to evaluate the use of plant adaptogens in the past and now, as well as to outline the prospects of their future applications. The use of natural adaptogens by humans has a rich history-they are used in recovery from illness, physical weakness, memory impairment, and other conditions. About 50 years ago, plant adaptogens were first used in professional sports due to their high potential to increase the body's resistance to stress and to improve physical endurance. Although now many people take plant adaptogens, the clinical trials on

  • A Critical Approach to Evaluating Clinical Efficacy, Adverse Events and Drug Interactions of Herbal Remedies.

    Izzo AA, Hoon-Kim S, Radhakrishnan R, Williamson EM · Phytotherapy research : PTR · 2016

    Systematic reviews and meta-analyses represent the uppermost ladders in the hierarchy of evidence. Systematic reviews/meta-analyses suggest preliminary or satisfactory clinical evidence for agnus castus (Vitex agnus castus) for premenstrual complaints, flaxseed (Linum usitatissimum) for hypertension, feverfew (Tanacetum partenium) for migraine prevention, ginger (Zingiber officinalis) for pregnancy-induced nausea, ginseng (Panax ginseng) for improving fasting glucose levels as well as phytoestrogens and St John's wort (Hypericum perforatum) for the relief of some symptoms in menopause. However, firm conclusions of efficacy cannot be generally drawn. On the other hand, inconclusive evidence of efficacy or contradictory results have been reported for Aloe vera in the treatment of psoriasis, cranberry (Vaccinium macrocarpon) in cystitis prevention, ginkgo (Ginkgo biloba) for tinnitus and intermittent claudication, echinacea (Echinacea spp.) for the prevention of common cold and pomegranat

  • Sexual Performance Anxiety.

    Pyke RE · Sexual medicine reviews · 2020

    Sexual performance anxiety (SPA) is one of the most prevalent sexual complaints; yet, no diagnosis is recognized for either gender. Thus, research into treatment has been minimal. Review the prevalence of SPA and its relation to sexual dysfunctions and anxiety disorders. Compare SPA to (non-sexual) performance anxiety and social anxiety (PA/SA). Apply pharmacologic principles to the known properties of drugs and phytotherapies to hypothesize treatments for SPA. Review SPA and PA/SA through PubMed searches for relevant literature from 2000 to 2018. Prevalence was estimated using population-representative surveys. For treatment results, controlled clinical trial results were prioritized over open-label trial results. SPA affects 9-25% of men and contributes to premature ejaculation and psychogenic erectile dysfunction (ED). SPA affects 6-16% of women and severely inhibits sexual desire. Cognitive behavior therapy and mindfulness meditation training have been proven effective for

  • Rise of herbal and traditional medicine in erectile dysfunction management.

    Ho CC, Tan HM · Current urology reports · 2011

    Herbal medicine long has been used in the management of sexual dysfunction, including erectile dysfunction. Many patients have attested to the efficacy of this treatment. However, is it evidence-based medicine? Studies have been done on animal models, mainly in the laboratory. However, randomized controlled trials on humans are scarce. The only herbal medications that have been studied for erectile dysfunction are Panax ginseng, Butea superba, Epimedium herbs (icariin), Tribulus terrestris, Securidaca longipedunculata, Piper guineense, and yohimbine. Of these, only Panax ginseng, B. superb, and yohimbine have published studies done on humans. Unfortunately, these published trials on humans were not robust. Many herbal therapies appear to have potential benefits, and similarly, the health risks of various phytotherapeutic compounds need to be elucidated. Properly designed human trials should be worked out and encouraged to determine the efficacy and safety of potential phytotherapies.
