Field Horsetail
Equisetum arvense
Field horsetail is one of the oldest plants still walking beside us, and old herbals treated it with real respect. Roman and Greek physicians, including Dioscorides and Pliny, recommended it to help stop bleeding and knit wounds, and its old folk name scouring rush hints at another practical use, since its gritty, silica-filled stems were once bundled up and used to scrub pots and polish pewter. Across European and Native American herbal traditions, horsetail tea was steeped as a gentle support for the kidneys and bladder, and its mineral richness earned it a lasting place as a traditional tonic for brittle hair, weak nails, and tired connective tissue. It traveled from utility herb to beauty cabinet over centuries, but the plant itself has hardly changed at all.

Traditional preparations.
A mild, mineral-rich infusion traditionally sipped for occasional support of hair, nails, and the urinary tract, taken in modest amounts and not as a daily long-term habit.
Traditionally, 1 teaspoon of the dried aerial stems is gently simmered in 250 ml of water for 10 minutes, then strained and sipped warm.
Safety.
Field horsetail contains an enzyme that breaks down vitamin B1, so it's meant for modest, short-term use, not daily long-term use, and should be avoided with a thiamine deficiency, heavy alcohol use, or during pregnancy and breastfeeding. Its diuretic action can interact with lithium and other diuretics, so use caution with kidney or heart conditions. Only young, properly identified stems are used, and it's not considered appropriate for children.
