Equisetum (also known as “cola de caballo” in Mexico) has a long history of medicinal uses, although modern sources include cautions with regard to its use. Apparently, these plants have a high content of thiaminase, which may induce edema and may cause lack of limb coordination, slow heart-rates, and cardiac irregularity.

Nevertheless, Equisetum has been widely used in many different cultures as a diuretic to reduce swelling caused by excess fluid retention and for urinary infections, bladder and kidney disorders. It has also found extensive application in medicine as a source of silica, which can amount to 25% of the plant’s dry weight.
