Also known as: Stinging Nettle, Nettle, Urtica dioica

Overview

Stinging nettle (*Urtica dioica*) is a plant native to Europe, Asia, and North Africa, valued for its nutrient-rich leaves and roots. It has a history of traditional use for conditions like benign prostatic hyperplasia (BPH), arthritis, and allergies. The plant is characterized by its anti-inflammatory and antioxidant properties, attributed to various bioactive compounds. Stinging nettle is available in several forms, including capsules, extracts, and teas. Research support for its efficacy is moderate, with a growing body of evidence, particularly for BPH. The quality of available evidence varies, with some high-quality systematic reviews and meta-analyses available. It's important to note that while generally considered safe, it can cause side effects and interact with certain medications, necessitating caution and awareness when using it as a supplement.

Benefits

Stinging nettle demonstrates notable benefits, particularly for men with benign prostatic hyperplasia (BPH). A meta-analysis indicated a significant reduction in the International Prostate Symptom Score (IPSS) with *Urtica dioica* compared to controls (SMD -10.47, 95% CI: -18.12 to -2.82, p = 0.007). While less extensively studied in humans, stinging nettle also exhibits anti-inflammatory and antioxidant effects, supported by in vitro and animal studies. The effect size for BPH symptom relief is moderate to large, suggesting clinical relevance. Benefits for BPH symptoms typically manifest within weeks to months of consistent use. Further research is needed to fully elucidate the extent and consistency of these benefits across diverse populations and conditions.

How it works

Stinging nettle exerts its effects through multiple biological pathways. Its anti-inflammatory action involves inhibiting pro-inflammatory cytokines and enzymes, while its antioxidant properties neutralize free radicals. In the urinary system, it may improve urinary flow and alleviate BPH symptoms. A key molecular target is 5-alpha reductase, an enzyme involved in converting testosterone to dihydrotestosterone, a hormone implicated in BPH. While the bioavailability of stinging nettle's active compounds is not definitively established, it is believed to be moderate. These mechanisms collectively contribute to the observed benefits of stinging nettle in managing BPH and potentially other inflammatory conditions.

Side effects

Stinging nettle is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects (occurring in >5% of users) include gastrointestinal upset and allergic reactions. Less common side effects (1-5%) may involve skin irritation and interactions with blood thinners. Rare side effects (<1%) include severe allergic reactions. Stinging nettle may interact with blood thinners, diabetes medications, and blood pressure medications. It is contraindicated in pregnancy and breastfeeding due to a lack of safety data. Caution is advised in patients with kidney or liver disease. It is important to monitor for any adverse reactions and consult with a healthcare provider before using stinging nettle, especially if you have pre-existing medical conditions or are taking medications.

Dosage

For BPH, a typical dosage ranges from 300 mg to 600 mg per day, although optimal dosages can range from 300 mg to 1200 mg per day depending on the condition being treated. Doses above 1200 mg per day are not commonly recommended. Stinging nettle is typically taken with meals to reduce gastrointestinal side effects. It is available in various forms, including capsules and extracts. The bioavailability may be enhanced when taken with fatty meals. There are no established required cofactors. It's important to consult with a healthcare provider to determine the appropriate dosage and timing for your specific needs and to ensure safety.
