Standing in ditches and damp places since time immemorial, field horsetail was nicknamed "horse's tail" or "fox's tail" by old herbalists, for its slender, rough silhouette. Rich in silica, this hardy perennial has accompanied European folk traditions as an ally of connective tissue, joints, and skin.

Traditional uses

Pain & inflammation

Traditional joint support

Horsetail was traditionally drunk as a tea to accompany joint and rheumatic discomfort, its richness in silica being linked by people of the past to the strength of connective tissue.

Skin

Compresses for skin and nails

Used externally, stem decoctions were applied as compresses or baths to support healing and strengthen brittle nails and hair.

Urinary system

A traditional diuretic tea

Historically regarded as a draining plant, horsetail featured in folk teas meant to promote urinary elimination and support kidney function.

Pain & inflammation

Baths for tired tissue

Foot or hand baths made with horsetail decoction were used in the countryside to soothe tired, swollen tissue after exertion.

Precautions

Before you use it

Do not use during pregnancy, breastfeeding, or in children without a healthcare professional's guidance. Avoid in cases of heart or kidney failure, as horsetail promotes water elimination and may disrupt electrolyte balance. Do not extend the cure beyond a few weeks without medical advice; prolonged use may affect the absorption of certain vitamins (notably B1). Consult a pharmacist or doctor if taking medication, particularly diuretics or heart treatments, due to possible interactions.
