Nettle, also known as stinging nettle (Urtica dioica), is a perennial flowering plant with a long history of use in traditional medicine. The leaves, stems, and roots of the nettle plant have been utilized for various purposes. The aerial parts (leaves and stems) are often used for conditions related to inflammation and allergies, while the root is more commonly associated with prostate health. Nettle contains a variety of bioactive compounds, including flavonoids, carotenoids, vitamins, minerals, and phenolic acids, which contribute to its potential therapeutic effects. It is available in several forms, including teas, tinctures, and capsules.
Quick answer
What it is: Nettle, also known as stinging nettle (Urtica dioica), is a perennial flowering plant with a long history of use in traditional medicine.
There is some promising evidence from human clinical trials supporting nettle's use for allergic rhinitis and benign prostatic hyperplasia (BPH). Studies suggest it can reduce symptoms of seasonal allergies and improve urinary flow in men with BPH. However, many studies are small, and more large-scale, well-designed trials are needed to confirm these effects and establish optimal dosages.

Where this remedy is being discussed across the web and community.
Dietary protocols studied for the conditions this remedy is associated with.
Anti-Inflammatory Diet
A whole-foods pattern designed to lower chronic, low-grade inflammation by emphasizing omega-3s, polyphenols, fiber, and minimizing ultra-processed foods, sugar, and seed oils.
The anti-inflammatory diet is not a single protocol but a synthesis of the patterns most consistently linked to lower inflammatory markers (CRP, IL-6, TNF-alpha) in human studies — Mediterranean-style eating, oily fish, abundant polyphenols, and low intake of ultra-processed foods, refined sugar, industrial seed oils, and excessive alcohol.
Foods to emphasize
Fatty fish 2–3x/week (salmon, sardines, mackerel, herring)
Extra-virgin olive oil
Berries, cherries, and other deeply colored fruit
Dark leafy greens and cruciferous vegetables
Turmeric, ginger, and culinary herbs
Green tea
Nuts (especially walnuts) and seeds (flax, chia)
Legumes and whole grains
Dark chocolate (≥70% cocoa) in moderation
Foods to avoid
Sugar-sweetened beverages and refined sugar
Ultra-processed snacks and ready meals
Industrial seed oils used at high heat (soybean, corn, sunflower, cottonseed)
Processed and cured meats
Refined flour products
Excess alcohol
Key principles
Cook with olive oil, finish with extra-virgin olive oil
Aim for 25–35 g of fiber per day from whole foods
Eat the rainbow — color diversity ~ polyphenol diversity
Limit added sugar to <25 g/day
Typical duration: A long-term eating pattern.
Why it may help
Joint Pain: Reductions in CRP and IL-6 on anti-inflammatory patterns translate to less pain and stiffness in arthritis trials.
Safe and flexible. Can be combined with Mediterranean, vegetarian, or plant-forward patterns.
Vegan Diet
A fully plant-based eating pattern that excludes all animal products — meat, fish, dairy, eggs, and honey.
A whole-food vegan diet emphasizes vegetables, fruit, legumes, whole grains, nuts, and seeds. It has been associated with improvements in body weight, blood lipids, and glycemic control, and is being studied for autoimmune and inflammatory conditions. It requires deliberate planning for vitamin B12, vitamin D, omega-3 (EPA/DHA), iodine, iron, zinc, and (sometimes) calcium.
Nuts and seeds (especially walnuts, chia, flax, hemp)
Fortified plant milks and nutritional yeast
Algae-based EPA/DHA supplement
Vitamin B12 supplement (non-negotiable)
Foods to avoid
Refined grains and sugar as the bulk of meals
Heavily processed vegan junk foods
Coconut and palm oils in excess
Key principles
B12 supplementation is required, not optional
Include a reliable iodine source (iodized salt or seaweed in moderation)
Get vitamin D from sun and/or a supplement
Combine grains and legumes across the day for complete protein
Choose calcium-fortified plant milk if not eating leafy greens daily
Typical duration: A long-term eating pattern.
Why it may help
Joint Pain: Several RCTs report meaningful improvements in pain, swelling, and CRP in rheumatoid arthritis patients on whole-food vegan diets.
Vegan diets can be excellent or deficient — quality depends on planning. Pregnant, breastfeeding, and growing children on vegan diets should be followed by a registered dietitian.
Vegetarian Diet
A plant-based eating pattern that excludes meat, poultry, and fish but typically allows eggs and/or dairy.
Vegetarian diets range from lacto-ovo (includes eggs and dairy) to lacto (dairy only) and ovo (eggs only). Done well, they are associated with lower rates of cardiovascular disease, type 2 diabetes, and some cancers. Done poorly, they can be high in refined grains and low in key nutrients (B12, iron, omega-3s, zinc).
Foods to emphasize
Legumes (lentils, chickpeas, beans, tofu, tempeh)
Whole grains (oats, quinoa, brown rice, whole wheat)
Vegetables and fruit, daily and varied
Nuts and seeds (almonds, walnuts, chia, flax, hemp)
The Autoimmune Protocol removes foods commonly implicated in immune activation and gut permeability — grains, legumes, dairy, eggs, nightshade vegetables, nuts, seeds, refined sugar, alcohol, and additives — for a 30–90 day elimination, followed by careful one-at-a-time reintroduction. It is most studied in Hashimoto's thyroiditis and inflammatory bowel disease.
Foods to emphasize
Quality meat, poultry, and seafood (especially wild-caught fatty fish)
Organ meats once or twice weekly
A wide variety of non-nightshade vegetables and leafy greens
Nuts and seeds (including seed-based spices like cumin, coriander)
Refined sugar and sweeteners
Alcohol
NSAIDs and food additives where possible
Key principles
Pair the elimination with sleep, stress management, and movement
Track symptoms in a journal during reintroductions
Reintroduce one food every 5–7 days and watch for symptom changes
Most people do NOT need to stay strict long-term — the goal is a personalized maintenance diet
Typical duration: 30–90 day strict elimination, then a structured staged reintroduction over weeks to months.
Why it may help
Joint Pain: Eliminates nightshades, gluten, and dairy — common reported triggers — to identify dietary contributors to inflammatory joint pain.
AIP is restrictive and best done with a practitioner familiar with the protocol, especially when active autoimmune disease is involved or in pregnancy/lactation.
Carnivore Diet
An all-animal-foods elimination diet consisting of meat, fish, eggs, and (optionally) dairy, with zero plant foods.
The carnivore diet is the most aggressive elimination diet — it removes every plant food (and therefore every fiber, lectin, oxalate, gluten, and FODMAP source) to isolate animal-food tolerance. Proponents use it primarily as a short-term diagnostic elimination to surface food triggers in autoimmune, gut, and inflammatory conditions. Long-term safety data is limited and observational.
Foods to emphasize
Ruminant meat (beef, lamb, bison) — emphasized for nutrient density
Pasture-raised eggs
Fatty fish (salmon, sardines)
Organ meats (liver, kidney) once or twice weekly
Bone broth and bone marrow
Animal fats (tallow, butter, ghee)
Salt to taste
Optional: aged hard cheeses, heavy cream
Foods to avoid
All grains, legumes, and seeds
All vegetables and fruit
Nuts and plant oils
Sugar and sweeteners
Most processed foods
Alcohol
Key principles
Eat to satiety — no calorie counting
Salt food liberally to maintain electrolytes
Prioritize fattier cuts over lean meats
Reintroduce foods one at a time after the elimination window to identify triggers
Best tracked with a clinician given the radical nature of the change
Typical duration: Typically run as a 30–90 day elimination, then food reintroductions one at a time.
Why it may help
Joint Pain: Used as an elimination diet to surface plant-based food triggers (nightshades, lectins) reported by some people to drive joint pain. No clinical trials.
Long-term effects on cardiovascular markers, bone health, and the gut microbiome are not well established. Avoid in chronic kidney disease, gout flares, or active eating disorders without medical supervision.
Linked nutrient deficiencies
Vitamin and mineral deficiencies commonly associated with the conditions this remedy may support.
Omega-3 Fatty Acids (EPA/DHA)
Essential fatty acid
Anti-inflammatory lipids critical for brain, joint, and skin health.
Low vitamin D status is one of the most widespread deficiencies globally and has been linked to autoimmune disease activity (Hashimoto's, MS), mood disorders, recurrent infections, and poor skin barrier function.
Common symptoms
Fatigue
Low mood
Frequent infections
Bone or muscle aches
Hair thinning
Food sources
Fatty fish (salmon, sardines)
Egg yolks
Cod liver oil
UV-exposed mushrooms
Fortified dairy
Lab markers to discuss
25-hydroxyvitamin D (target 40–60 ng/mL per most functional ranges)
Reference intake: Adults 600–800 IU/day RDA; functional medicine often targets 2,000–5,000 IU/day with monitoring.
Supplementation notes: Take with a fat-containing meal. Pair with vitamin K2 (MK-7) when supplementing higher doses long-term.
Why it matters here
Joint Pain: Deficiency is associated with chronic widespread pain and osteoarthritis progression.
Hypothyroidism: Frequently low in hypothyroid patients; influences immune tolerance.
Selenium
Trace mineral
Essential for thyroid hormone metabolism and antioxidant defense (glutathione peroxidase).
Selenium reduces TPO antibodies in Hashimoto's and supports T4→T3 conversion. Deficiency is implicated in thyroid autoimmunity and viral susceptibility.
An estimated 50% of adults consume below the EAR. Low magnesium is linked to insomnia, anxiety, migraines, muscle tension, and poor blood sugar regulation.
Common symptoms
Muscle cramps or twitches
Poor sleep
Anxiety, irritability
Headaches/migraines
Constipation
Food sources
Pumpkin seeds
Dark leafy greens
Almonds and cashews
Dark chocolate (85%+)
Black beans
Avocado
Lab markers to discuss
RBC magnesium (more sensitive than serum)
Serum magnesium
Reference intake: 310–420 mg/day RDA depending on age and sex.
Supplementation notes: Glycinate for sleep/anxiety, citrate for constipation, threonate for cognitive/brain effects. Avoid magnesium oxide (poorly absorbed).
Why it matters here
Joint Pain: Supports muscle relaxation and reduces secondary pain.
Iron (Ferritin)
Mineral
Required for oxygen transport, thyroid hormone conversion, and energy production.
Low zinc is linked to recurrent infections, acne, slow wound healing, leaky gut, and impaired taste/smell. Often deficient in vegetarians and those with gut malabsorption.
Common symptoms
Frequent colds/infections
Acne or slow-healing skin
Loss of taste or smell
Hair loss
White spots on nails
Food sources
Oysters
Beef and lamb
Pumpkin seeds
Cashews
Lentils and chickpeas
Lab markers to discuss
Plasma or serum zinc
Zinc/copper ratio
Reference intake: 8–11 mg/day RDA.
Supplementation notes: Take away from iron and calcium. Long-term high-dose zinc depletes copper — pair with ~1 mg copper if dosing >30 mg/day.
Why it matters here
Hypothyroidism: Zinc supports TSH and thyroid hormone production.
Nettle may exert its effects through anti-inflammatory, antioxidant, and immunomodulatory actions, potentially influencing various physiological pathways.
How it works in more detail
Nettle's anti-inflammatory properties are thought to be due to its ability to inhibit several inflammatory pathways, including those involving prostaglandins and leukotrienes. It may also modulate immune responses by affecting T-cell activation and cytokine production. For allergic rhinitis, nettle may interfere with histamine receptors and inhibit mast cell degranulation, thereby reducing allergic symptoms. In the context of benign prostatic hyperplasia (BPH), nettle root is believed to influence hormone metabolism, specifically by inhibiting the binding of sex hormone-binding globulin (SHBG) to testosterone, and by affecting prostate cell growth.
How to use
Always consult a qualified clinician.
