At first glance, stinging nettle (Urtica dioica) doesn’t sound like something you’d want to drink — after all, it’s known for its sting. But beneath its prickly exterior lies a powerhouse herb that’s been used for centuries as a natural remedy.
When brewed into tea, nettle transforms into a nutrient-rich drink that offers several potential health benefits.

1. Helps Regulate Blood Sugar Levels

Early research suggests that nettle tea may help stabilize blood sugar levels in people with diabetes.
Some small studies show a decrease in fasting glucose and even HbA1c, which reflects long-term blood sugar control.

However, experts emphasize that nettle tea should never replace prescribed medications.
“If you have diabetes and want to try nettle tea, talk to your doctor first,” advises Palma. “It can be a good complement — not a substitute.”

2. Supports Prostate and Urinary Health

Nettle has a long history in herbal medicine for helping men with benign prostate hyperplasia (BPH) — a noncancerous enlargement of the prostate gland that causes frequent or painful urination.

“Studies suggest that nettles may slow prostate cell growth and reduce inflammation,” says Palma. “Some people notice improved urinary flow and fewer symptoms.”
Still, it’s best to consult your healthcare provider before using nettle for prostate issues.

3. May Ease Seasonal Allergies

When pollen season strikes, a warm cup of nettle tea might offer mild relief.
Some studies show that compounds in nettle can act like natural antihistamines, helping to calm sneezing and congestion.

“The evidence is mixed,” Palma admits. “But for mild allergies, it’s worth trying alongside standard allergy medications.”

4. Can Help Keep Blood Pressure in Check

Nettle tea isn’t an official treatment for hypertension, but early evidence hints that it may gently lower blood pressure in some individuals.
Its natural compounds may relax blood vessels and improve circulation.

“Regularly drinking nettle tea might help support healthy blood pressure,” says Palma. “Just don’t stop your prescribed medication — always discuss with your doctor first.”

5. Promotes Healthy Vision

Rich in antioxidants like lutein and zeaxanthin, nettle tea can play a small part in protecting your eyes from age-related decline.
These compounds are linked to a reduced risk of macular degeneration, diabetic retinopathy, and uveitis (eye inflammation).

“Nettle tea can’t replace eye exams or medical treatments,” Palma notes, “but its antioxidants support long-term eye health.”

How to Brew Nettle Tea

You can buy nettle tea in ready-to-steep bags or loose dried leaves.
Here’s how to make a cup at home:

1. Add a teabag or a teaspoon of dried nettle leaves to your cup.

2. Pour 8–10 ounces of boiling water over it.

3. Cover and steep for 5–10 minutes — the longer, the stronger.

4. Strain (if using loose herbs) and add honey if you prefer a softer taste.

Pro tip: For a richer flavor, combine nettle with mint or lemon balm.

Who Should Be Cautious

While generally safe, nettle tea isn’t for everyone. Avoid or use with care if you:

• Take blood pressure, blood thinner, diuretic, or diabetes medications.

• Are pregnant or have kidney issues.

• Have allergies to nettle — reactions may include itching, hives, or difficulty breathing.

Also, since nettle is a natural diuretic, avoid drinking it right before bed unless you like midnight bathroom trips.

The Bottom Line

Nettle tea is more than just an herbal trend — it’s a centuries-old remedy backed by promising modern research.
It offers antioxidants, vitamins, and minerals that can support your immune system, heart, and overall wellness.

Still, it’s not a cure-all.
As Palma reminds, “Nettle tea can be part of a healthy diet, but it’s no replacement for proper medical care. Always check with your healthcare provider before adding it to your routine.”

So next time you’re looking for a warm, earthy cup that does more than comfort — pour yourself some nettle tea.
