Where does horsetail grow?

Horsetail can be found throughout Europe, in fields or forests, mainly in humid places (close to running water). The horsetail can reach 50 cm in height.

When to harvest horsetail?

Horsetail normally grows from May to June (July to August in the mountains) in Europe, including Switzerland. The green stems of the horsetail can be harvested from May to June (in Europe) and then must undergo a drying process, as observed by the Swiss druggist Claude Roggen in his book “Les secrets du druide”, published by Bois Carré. He advises harvesting from untreated and dry fields, he also recommends avoiding harvesting from wetlands due to contamination by a fungus ( Ustilago equiseti ).

Comments

– Like the fern, the horsetail does not have flowers and reproduces through spores.

– Its scientific name Equisetum arvense comes from Latin and means respectively: horse ( Equus ), tail ( setum ) and fields ( arvense ).

– A Brazilian study carried out mainly by researchers from the Federal University of Goiás, in Brazil, showed that horsetail (E. arvense) produced a diuretic effect comparable to hydrochlorothiazide (25 mg), a molecule used against hypertension. The effect of horsetail was superior to that of a placebo. This study was published in 2014 in the scientific journal Evidence-Based Complementary and Alternative Medicine .
