5 Powerful Benefits of Nettle Tea for Your Health

Spring is the moment nature gives us the opportunity to strengthen our bodies with the healing power of nettle. From March to May, young leaves are at the peak of their nutritional value – the perfect time to add fresh nettle to our menu. If we want a spring detox, a warm cup of nettle tea in the morning is one of the most accessible ways to do it. Here are the health benefits:

1. Nettle Tea and the Lymphatic System – The Spring Cleanse

The lymphatic system is the quiet guardian of our immunity. It collects cellular waste, filters toxins and carries them to the organs for elimination. Unlike blood, lymph has no pump of its own – it relies on movement, breathing and proper nutrition.

Nettle (Urtica dioica) stimulates the lymphatic system, supporting the kidneys in removing toxins from the body.¹ The flavonoids and chlorophyll in nettle act as mild anti-inflammatory agents, reducing tissue congestion and supporting better lymphatic flow.

Why is morning the ideal time? The body is in its natural cleansing mode after overnight regeneration, and warm liquid further stimulates lymphatic flow. A cup of warm nettle tea on an empty stomach – before coffee, before breakfast – signals the body to accelerate its natural detox.

2. Nettle Tea Iron

Nettle contains iron. Research confirms that processed nettle is a good dietary source of iron and calcium. ² The iron in nettle is non-heme (plant-based) iron, which is harder to absorb than animal iron. Studies have also found that only a small portion of the iron in dried leaves actually passes into the infusion itself. ³

This means that nettle tea is not a standalone solution for iron deficiency, but it is a valuable addition to a balanced diet – especially when combined with vitamin C.

3. Nettle Tea with Lemon – Maximum Iron Absorption

Lemon turns nettle tea into a significantly more effective source of iron. Vitamin C transforms iron into a more easily absorbable form that the body can absorb more efficiently, ⁴ while simultaneously neutralising phytates and polyphenols – compounds that would otherwise block iron absorption. ⁵ The result: more iron reaches your cells, more energy for you.

Practical tip: Wait for the tea to cool before adding lemon – above 60°C, vitamin C breaks down and loses its properties. You can also add a teaspoon of honey at this stage for natural sweetness and its own antibacterial benefits.

4. Nettle Tea Diuretic Effect

The diuretic effect of nettle is one of its best-documented properties. ⁶ It helps the body shed excess salts and fluids, which reduces swelling, and supports the function of the kidneys and urinary tract. More frequent urination is a normal and expected effect, especially at the beginning – a sign that the body is working.

Important: Drink enough water throughout the day to compensate for fluid loss. If you are taking diuretic medication or have kidney problems, consult your doctor before regular use.

5. Antioxidant and Anti-Inflammatory Action

Nettle contains flavonoids (quercetin and kaempferol), polyphenols and carotenoids with proven antioxidant and anti-inflammatory action. ⁷ Antioxidants neutralise free radicals – unstable molecules that damage cells and accelerate ageing.

The anti-inflammatory properties of nettle are particularly valuable in cases of chronic inflammation, fatigue and weakened immunity – conditions many of us recognise after winter. Regular consumption of nettle tea can be a gentle but steady ally for the body in the fight against oxidative stress.

Smart Tip: Bought Fresh Nettle for Cooking? Don’t Pour the Water Away

If you have picked up fresh nettle from the market, here is a simple and incredibly valuable trick. Before cooking the nettle, soak it in hot water – and keep that water.

Here’s how to do it properly:

1. Clean the nettle carefully – using gloves, remove any yellowed or damaged leaves. Use only the fresh, bright green parts.
2. Pour hot (not boiling) water over it – around 80°C is enough to neutralise the stinging hairs without destroying the nutrients.
3. Do not add salt – salt affects the mineral balance and can reduce absorption. Keep the water clean.
4. Keep the water, do not pour it away. This liquid contains minerals, chlorophyll and nutrients released from the leaves during soaking.
5. Drink it as tea at the morning– strain, wait until it cools to around 50°C, add drops of lemon and a teaspoon of honey if desired.

Who Should Be Careful

Nettle tea is safe for most people, but is not recommended for pregnant women, people taking diuretic medication, people with kidney disease, people taking anticoagulants. When in doubt, consult your doctor.
