Horsetail (Equisetum arvense): A Forgotten Herbal Ally for Hair, Bones, Skin and Kidneys

You’ve likely walked past it without a second thought – that tall, green, brush-like plant growing along field edges and quiet footpaths. But Equisetum arvense, commonly known as horsetail, is one of the oldest surviving plant species on Earth — and one of the most mineral-rich herbs in traditional herbal medicine.

In this post, we’ll explore the benefits of horsetail, how to use it safely, some fascinating historical uses, and why it’s an essential part of my Detox & Kidney Support herbal tea.

What is Horsetail?

Horsetail is a prehistoric plant that has been growing on Earth for over 350 million years. It belongs to a family of non-flowering plants and has a unique ability to absorb and concentrate minerals from the soil — making it one of the most mineral-dense herbs available in nature.

It’s especially rich in silica (organic silicon), a vital compound that plays a key role in skin elasticity, connective tissue repair, hair strength, and bone health.

Health Benefits of Horsetail

Here’s why herbalists across the world continue to reach for horsetail:

1. Supports Hair, Skin and Nails

Thanks to its high silica content, horsetail strengthens hair shafts, reduces breakage, and encourages nail growth. It also supports collagen production, making it an excellent herb for ageing skin.

2. Promotes Bone Health

Silica helps in the formation and maintenance of healthy bones and connective tissue. Horsetail is often included in mineral-rich infusions for women at risk of osteoporosis or recovering from fractures.

3. Natural Diuretic

Horsetail has a gentle diuretic action, which helps flush out excess water, reduce bloating, and support kidney and bladder function. It can be particularly helpful in managing urinary tract health.

4. Wound Healing and Skin Support

Applied externally as a wash or compress, horsetail may soothe irritated skin, support the healing of wounds, eczema, and minor burns, and reduce inflammation.

What Makes Horsetail So Special?

• Up to 10% organic silica – in a form that is better absorbed than many synthetic supplements

• Rich in flavonoids, saponins, potassium salts, and small amounts of calcium and magnesium

• Known for its mild anti-inflammatory and astringent properties

Herbalist’s Fun Fact

In the past, horsetail was used by craftspeople to polish metal and wood because of its high silica content — nature’s own fine sandpaper!

How to Use Horsetail Safely

Important: To extract the beneficial silica, horsetail should be simmered, not just steeped like a typical tea.

Traditional mineral-rich infusion:

• Add 1 tablespoon of dried horsetail to 300 ml cold water

• Bring to a simmer and cook gently for 15–20 minutes

Tip: Combine with nettle or birch leaves for enhanced remineralising effects.

Safety Notes:

• Avoid long-term daily use without breaks. Horsetail contains thiaminase, an enzyme that can interfere with vitamin B1 absorption.

• Not recommended during pregnancy, breastfeeding, or in individuals with kidney dysfunction, unless supervised by a practitioner.
