    In many parts of Europe, herbal supplements are considered standard medical treatment for BPH. Although herbs for BPH are available without prescription, men wishing to take them should be monitored by a physician.

    A concentrated extract made from the roots of the nettle plant may increase urinary volume and the maximum flow rate of urine in men with early-stage BPH.6 It has been successfully combined with both saw palmetto and pygeum to treat BPH in double-blind trials.7 It has also been shown in a double-blind trial, when used by itself, to relieve symptoms of BPH and to improve disease severity.8 An appropriate amount appears to be 120 mg of nettle root extract (in capsules or tablets) twice per day or 2 to 4 ml of tincture three times per day.

    has historically been used for joint pain. Topical application with the intent of causing stings to relieve joint pain has been assessed in preliminary and double-blind trials. The results found intentional nettle stings to be safe and effective for relieving the pain of osteoarthritis. The only reported adverse effect is a sometimes painful or numbing rash that lasts 6 to 24 hours.

    The historic practice of applying nettle topically (with the intent of causing stings to relieve arthritis) has been assessed by a questionnaire study.9 The nettle stings were reported to be safe except for causing a sometimes painful, sometimes numbing rash lasting 6 to 24 hours. Further studies are required to determine whether this practice is therapeutically effective.

    In an isolated double-blind trial, nettle leaf led to a slight reduction in symptoms of hay fever—including sneezing and itchy eyes.10 However, no other research has investigated this relationship. Despite the lack of adequate scientific support, some doctors suggest taking 450 mg of nettle leaf capsules or tablets two to three times per day, or a 2–4 ml tincture three times per day for people suffering from hay fever.

  • Kidney and Urinary Tract Health

    Urinary Tract Infection

    Nettle may relieve UTI symptoms by increasing urinary volume and helping to flush bacteria out of the urinary tract.

    Asparagus (Asparagus officinalis), birch (Betula spp.), couch grass (Agropyron repens), goldenrod (Solidago virgaurea),horsetail, Java tea (Orthosiphon stamineus), lovage (Levisticum officinale), parsley (Petroselinum crispum), spiny restharrow (Ononis spinosa), and nettle are approved in Germany as part of the therapy of people with UTIs. These herbs appear to work by increasing urinary volume and supposedly helping to flush bacteria out of the urinary tract.11Juniper is used in a similar fashion by many doctors. Generally, these plants are taken as tea.

    Many tonic herbs, which are believed to strengthen or invigorate organ systems or the entire body, can be taken safely every day during pregnancy. Examples include dandelion leaf and root, red raspberry leaf, and nettle. Dandelion leaf and root are rich sources of vitamins and minerals, including beta-carotene, calcium, potassium, and iron. Dandelion leaf is mildly diuretic (promotes urine flow); it also stimulates bile flow and helps with the common digestive complaints of pregnancy. Dandelion root is traditionally used to strengthen and invigorate the liver.12

What Are Star Ratings?
×
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)

Nettle has a long history of use. The tough fibers from the stem have been used to make cloth and cooked nettle leaves were eaten as vegetables. From ancient Greece to the present, nettle has been documented for its traditional use in treating coughs, tuberculosis, and arthritis and in stimulating hair growth.
