Benefits and applications of field horsetail
For centuries, an inconspicuous wayside plant has been considered a true miracle cure in natural medicine and ecological gardening: field horsetail.

What is common horsetail (field horsetail)?
Botanically, the plant is considered Field horsetail is designated. It belongs to the spore plants and is a true „living fossil,“ as horsetails already populated our Earth during the age of dinosaurs and grew into giant tree-like structures at that time. Today, the plant remains significantly smaller at about 10 to 50 centimeters in height, but its active ingredients are more potent than ever.
When professionals talk about Equisetum arvense Ingredients and Uses speak, a specific element is clearly at the center: silica. Up to 10 percent of this valuable silicon compound is contained in the plant's green, fir-tree-like stems. The Healing power of silicic acid in naturopathy has been undisputed for generations. It is not only an essential building block for the human body but also elementary for the stability of plant cell walls. In addition to silicic acid, field horsetail contains valuable flavonoids (secondary plant compounds), potassium, saponins, and organic acids, making it a true all-rounder in herbal medicine.
As a so-called indicator plant, the Field horsetail in the wild, often points to compacted, loamy, and waterlogged soils. Its deep roots can reach up to two meters into the earth, which sometimes makes it unpopular with farmers, but allows it to transport valuable minerals from the deepest soil layers upwards.
The health benefits of horsetail
The traditional Zinnkraut application ranges from supporting wound healing to relieving chronic conditions. The plant's active ingredients target precisely where structure and cleansing are needed in the body.

Silicic acid (silicon) plays a significant role in the formation and cross-linking of collagen and elastin in the human body. An adequate supply of Silica for hair and nails ensures that hair loss caused by nutrient deficiency can be reduced and brittle, soft fingernails can regrow strong and resilient.
In addition, regular consumption supports the natural strengthening of connective tissue. Anyone suffering from weak connective tissue, fine cracks in the skin, or cellulite can strengthen, firm, and make the tissue more elastic from the inside out with the trace element silicon.

A correctly prepared horsetail tea is the best-known and most commonly used home remedy. Because the crystalline silicic acid does not dissolve as easily from the hard plant cell walls as the essential oils in other herbs (e.g., chamomile or peppermint), simply pouring hot water over it is not sufficient. The tea must be boiled.
Preparation of an effective tea:
- Add about 2 to 3 teaspoons of dried Field horsetail into a pot.
- Fill the pot with 250 to 300 ml of cold water.
- Bring the water to a boil and let the broth simmer over low heat for a good 15 to 20 minutes.

- Seal the jar well and let it stand in a warm, bright place for about four to six weeks (but protected from direct midday sun).
- Shake the bottle gently every other day to dissolve the active ingredients and prevent mold.
- Afterward, filter the liquid through coffee filter paper or a fine cloth and fill the finished tincture into dark dropper bottles.

Common Horsetail in the Garden: An Ecological Wonder
Not only humans, but also nature and our vegetable patch benefit enormously from this primeval plant. Anyone who wants to garden organically can hardly avoid horsetail.

Plant protection products and organic fertilizers
The high silica content acts like a protective shield for leaves and stems in the garden. When the solution is applied to crops, silicon enormously strengthens the outer cell wall of the leaves. They become so hard and robust that invading fungal spores or biting insects have little to no chance.
A homemade, well-fermented Comfrey manure as a natural plant protection agent is in gardening circles the absolute Home remedies for powdery mildew and aphids. Additionally, the highly mineral-rich liquid manure serves as an excellent Organic fertilizer for tomatoes and roses. Tomatoes, which are susceptible to the dreaded late blight in a rainy summer, or roses, which often suffer from black spot, can be preventatively protected by regularly watering them with horsetail. The plant not only provides structure but also valuable potassium, which promotes fruit development.
Make borage
While a plant slurry ferments for weeks, smells extremely strong, and primarily functions as a root fertilizer, a decoction is much quicker to use, hardly smells, and is perfect for foliar feeding as well as direct prevention against fungal diseases.
Here's a short, practical Instructions for making tin herb broth:
- Step 1: Soak 100 g of dried herb (or 1 kg fresh) in 10 liters of collected rainwater for 24 hours.
- Step 2: Cook this approach on a low flame in a large pot for about 30 to 45 minutes the next day. The long cooking time is also important here to make the silica plant-available.
- Step 3: Let the broth cool completely, then strain it through a cloth.
- Step 4: To spray, dilute the decoction in a 1:5 ratio with clean water. On dry days, spray this solution finely atomized over the entire leaves of the affected plants in the morning (never in direct sunlight). Repeat this every one to two weeks with high fungal pressure.
Collecting and drying Common Purslane correctly

These green shoots are ideally harvested between late May and mid-July. During these early summer months, the silica and fresh nutrient content is at its highest, while the stems are still juicy and not too woody.
Um Harvesting and drying Common Yarrow correctly To be able to, it's best to cut the sprigs with scissors in the lower third during dry, sunny weather (after the morning dew has dried). Loosely bundle the stems and hang them upside down in a airy, warm, and shaded place. Avoid direct sunlight, as it destroys the valuable active ingredients. As soon as the sprigs rustle and break immediately with a light touch, they are completely dry. Strip the needles from the main stem and store the herb in an airtight container in paper bags or dark screw-top jars.
Caution when collecting! The risk of confusion

- The length test (The most important feature): Consider the main stem and one of the emerging green side branches. On the main stem, where the branches originate, there is a black, toothed sheath (the so-called leaf sheath).
- At Field horsetail Is the lowest link of the side branch always clear longer as this black leaf sheath of the main stem.
- At the toxic Marsh horsetail is the first link of the side branch always shorter as long as (or at most as long as) the associated leaf sheath on the main stem.
- If you are not one hundred percent sure about a plant in nature, do not take any risks. It is better to buy the herb dried and in controlled, safe organic quality at a pharmacy, health food store, or qualified online retailer.
