When professionals talk about Equisetum arvense Active Ingredients and Uses speaking, one particular 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 natural medicine has been undisputed for generations. It is not only an essential building block for the human body, but also fundamental to 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 indicate compacted, clayey, and waterlogged soils.

Additionally, regular consumption supports the Natural strengthening of connective tissue. People suffering from weak connective tissue, fine cracks in the skin, or cellulite can use the trace element silicon to firm, tighten, and make the tissue more elastic from the inside out.

  • 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 reduced heat for a good 15 to 20 minutes on the stove.

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 greatly strengthens the outer cell wall of the leaves. They become so hard and robust that invading fungal spores or biting insects stand little chance.

A self-starter, well-fermented Comfrey slurry as a natural plant protection agent is in garden circles the absolute Home remedies for powdery mildew and aphids. Furthermore, 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 during rainy summers, or roses, which often suffer from black spot, can be preventatively protected by regular watering with horsetail. The plant not only provides structure but also valuable potassium, which promotes fruit development.

To make kraut

While a plant manure ferments for weeks, smells extremely strong, and primarily functions as a root fertilizer, a decoction is ready for use much faster, barely smells, and is perfect for foliar feeding as well as direct prevention against fungal diseases.

Here is a short, practical Instructions for making tin herb broth:

  • Step 1: Soak 100 g dried herbs (or 1 kg fresh) in 10 liters of collected rainwater for 24 hours.
  • Step 2: Cook this approach for about 30 to 45 minutes on low heat in a large pot the next day. The long cooking time is also important here to make the silica plant-available.
  • Step 3: Let the broth cool completely and then strain it through a cloth.
  • Step 4: To spray, dilute the brew at a ratio of 1:5 with clear water. On dry days, spray this solution finely atomized over all the leaves of the affected plants in the morning (never in direct sunlight). Repeat this every one to two weeks if there is high fungal pressure.

Um Harvesting and drying zincweed correctly To be able to do this, it is best to cut the shoots with pruning shears in the lower third in dry, sunny weather (after the morning dew has dried). Bundle the stems loosely and hang them upside down in a airy, warm, and shaded place. Avoid direct sunlight, as it destroys the valuable ingredients.

  • The length test (The most important feature): Consider the main stem and one of the branching green side shoots. On the main stem, where the branches originate, there is a black, serrated sheath (the so-called leaf sheath).
    • At Field horsetail Is the bottom link of the lateral branch always clear longer as this black leaf sheath of the main stem.
    • In the toxic Marsh horsetail is the first link of the side branch always shorter as long as (or at most the same length as) the corresponding leaf sheath on the main stem.
