Here is how to make horsetail tea in one line: it is a mild, grassy, caffeine-free infusion made by simmering or steeping dried field horsetail (Equisetum arvense) in hot water for several minutes until the water turns pale gold-green with a soft, hay-like flavour. Because the plant is naturally high in silica, many people give it a short, gentle simmer rather than a quick steep. Below is a simple horsetail tea recipe, the identification point that matters most, and a few honest safety notes.
If you are brand new to loose botanicals, the general mechanics of steeping temperature, timing and strength are covered in our guide on how to brew herbal tea, and the wider question of what a tisane actually is lives in what is herbal tea. This page stays focused on the horsetail itself.
What Horsetail Tea Is
Horsetail tea is an herbal infusion made from the dried stems of field horsetail, a feathery, jointed green plant that grows in damp ground across Europe, North America and much of the temperate world. Brew it and you get a pale, gold-green cup with a gentle, grassy, earthy, faintly hay-like taste — closer to a soft green meadow note than to anything floral or fruity. It carries no caffeine, so it sits easily in the evening.
The plant itself is a genuine curiosity. Equisetum is one of the oldest surviving plant lineages on Earth, a living relative of the giant horsetails that grew in ancient forests long before flowering plants existed. Its stems feel slightly rough because they are rich in silica, and that mineral content is part of why the plant has such a long folk-tea history across the European countryside, where dried horsetail was simmered as a humble country brew for generations. Drinking equisetum tea is, in a small way, sipping something very old.
Identify Your Horsetail: Field, Not Marsh
This is the one step you should not skip. If you are gathering your own, use correctly identified field horsetail (Equisetum arvense), the low, bushy spring shoots — and learn to tell it apart from the taller marsh horsetail (Equisetum palustre) and other look-alikes, which are best avoided. When in any doubt at all, don't gather it: buy dried horsetail from a reputable herb supplier instead, where the species is named on the label.
If you do forage, pick only from clean, unsprayed ground well away from roadsides, drains and treated lawns, because the plant readily takes up whatever is around it. Harvest the young green stems, rinse them, and dry them fully before storing. Correct identification and a clean source matter far more here than any brewing trick, so treat this as the real first step of the recipe.
What You Need
- Dried field horsetail — about 1 to 2 teaspoons of the chopped dried herb per cup (roughly 240 ml of water). Start at 1 teaspoon and adjust to taste.
- Fresh water — one cup per serving.
- Optional honey — a small drizzle to soften the grassy edge (never give honey to children under 12 months).
- Optional lemon — a squeeze brightens the cup and lifts the colour.
- Optional greens to blend — a little mint, or a nettle-style green herb, rounds out the flavour if plain horsetail tastes too hay-like for you.
How to Make Horsetail Tea, Step by Step
Here is how to make horsetail tea two reliable ways — a gentle simmer, which suits this silica-rich plant, or a covered steep when you want something quicker. Both give you a proper field horsetail tea, so pick whichever fits your kitchen.
- Measure. Put 1 to 2 teaspoons of dried horsetail per cup into a small pot (for the simmer method) or into a mug or teapot (for the steep method).
- Heat the water. For a simmer, add the water to the pot with the herb. For a steep, boil the water and let it settle for a few seconds so it is just off the boil.
- Simmer or steep. For the simmer, bring it to a gentle simmer — not a rolling boil — and hold it for about 5 to 10 minutes. For the steep, pour the just-off-boil water over the herb and cover the cup for about 10 minutes so nothing escapes with the steam.
- Strain well. Pour through a fine strainer or a piece of muslin. Horsetail can shed fine bits, so strain it more thoroughly than you would a leaf tea.
- Finish and serve. Taste, then add honey, lemon or a mint leaf if you like, and serve hot. A longer, slower simmer will draw out more of the plant's silica and minerals and deepen both colour and flavour, so lengthen the simmer if you want a fuller cup — while keeping the overall habit occasional (more on that below).
This little table sums up the timing:
| Method | Time | Note |
|---|---|---|
| Covered steep | ~10 min | Quick and soft; use just-off-boil water and keep the lid on. |
| Gentle simmer | 5-10 min | Suits this silica-rich plant; draws out more than a quick steep. |
| Long slow simmer | 15-20 min | Deepest colour and minerals; keep this an occasional treat. |
Ways to Adjust the Flavour
Plain horsetail is deliberately mild, which makes it easy to shape to your taste. If the grassy, hay-like note feels too plain, a few tweaks help:
- Blend it. Steep the horsetail alongside a little mint, lemon balm or a nettle-style green for a rounder, fresher cup.
- Brighten it. A squeeze of lemon lifts the earthiness and warms the colour of the brew.
- Sweeten lightly. A small drizzle of honey softens the edges without burying the tea's own character.
- Serve it cold. Brew it a touch stronger, chill it, and pour it over ice for a clean, grassy iced infusion in warm weather.
Storing Dried Horsetail
Keep the dried herb in an airtight jar, out of direct light and away from heat and damp — a cool cupboard is ideal. Dried well and stored properly, horsetail holds its character for up to a year, though it is always at its best in the first several months. If it smells musty or looks discoloured, compost it and start fresh. Buy or dry only what you will realistically drink, since this is a tea to enjoy now and then rather than by the potful every day.
A Few Safety Notes (Non-Medical)
Horsetail is a traditional folk tea, not a remedy, so treat it as a pleasant occasional cup rather than a daily fixture. A practical reason sits behind that advice: horsetail naturally contains an enzyme called thiaminase, which is why herbalists have long suggested keeping intake occasional rather than drinking large amounts every day for long stretches. Enjoy it now and then and you sidestep the concern entirely.
A few specifics are worth knowing. Use only correctly identified field horsetail from a clean source; horsetail tea is traditionally avoided during pregnancy; and anyone who is breastfeeding, has kidney concerns, or takes any medication (including water tablets, sometimes called diuretics) should check with their own healthcare provider before making it a habit. Responses vary from person to person, and none of this is medical advice — it is general, food-first information. If a cup does not agree with you, simply stop.
Once you are comfortable with horsetail, the same gentle-simmer approach carries over nicely to other rooty, earthy country brews — for example our guides to making burdock tea and making goldenrod tea, both of which reward the same patience and clean sourcing.
