How to take Horsetail

These are the everyday prep instructions for Horsetail — covered once here so each use case below can focus on what's specific to that purpose.

What makes Horsetail work

Horsetail contains silica — one of the highest plant sources of silica — supports bones, hair, and nails. It's been used since Roman times for joint and connective tissue support.

Decoction
Simmer 1 tablespoon of the dried root or bark in 2 cups of water for 20–30 minutes (lid mostly on). Strain and sip. Decoctions are for hard plant parts that won't give up their actives to a quick steep.
Tincture
Take 30–60 drops in a small glass of water 1–3 times a day. Tinctures are alcohol or glycerin extracts — fast-absorbing, convenient for daily use and travel.
Capsule
Swallow 1–2 capsules (typically 300–600 mg) with water, 1–2 times a day. The easiest form if you don't like the taste.
Dosage

Decoction: 1-2 tsp dried in 8oz simmered 15 min, 1-2x daily; not for long-term continuous use (rotate weekly)

What to look for when buying: Dried aerial parts (only spring shoots), tincture, capsule, and tea.

The general prep above applies to every use below. These cards explain what Horsetail supports, why it works for each purpose, and what to notice.

How to use Horsetail for energy and stamina

Take daily in the morning — capsule, tea, or tincture — for 4–8 weeks.

Why it works for energy and stamina

These aren't coffee replacements — they don't kick in fast. Instead they build your body's ability to make and sustain energy, so the lift is steady and lasting rather than spiky and crashy.

What you'll notice
  • Steady energy across the day
  • No coffee jitters or crashes
  • Better stamina for hard weeks
  • Pair well with sleep and protein
  • A foundation for long-term energy

How to use Horsetail for wound care and skin healing

Apply the salve or infused oil 2–3 times daily to clean skin.

Why it works for wound care and skin healing

Healing herbs contain compounds that calm inflammation, fight surface bacteria, and signal your skin to repair itself. They work best on small, clean wounds — anything deep, dirty, or refusing to heal needs a doctor, not just an herb.

What you'll notice
  • Speed minor wound healing
  • Calm bites, stings, and rashes
  • Reduce scarring over time
  • A clean, plant-based first-aid option
  • Pair beautifully with calendula salve

How to use Horsetail for everyday skin care

Use the infused oil, salve, or tea as a wash on clean skin daily.

Why it works for everyday skin care

Skin-supporting herbs calm inflammation, support the skin's repair process, and balance the natural community of bacteria living on your skin. Daily, gentle use over weeks does more than a one-off treatment.

What you'll notice
  • Calm redness and irritation
  • Support skin's natural repair
  • Add a gentle plant-based step to your routine
  • Pair beautifully with simple cleansers
  • A kinder alternative to harsh actives
