Medicinal uses<br />

Uses supported by clinical data<br />

An open clinical trial has indicated a possible diuretic effect (40).<br />

Uses described in pharmacopoeias and well-established documents<br />

Used <strong>int</strong>ernally for kidney and bladder diseases, oedema and as an adjuvant<br />

in slimming diets (41). It is applied as irrigation therapy for infectious<br />

and inflammatory diseases of the genitourinary tract, and kidney<br />

stones (12, 23, 42). Used externally as supportive treatment for slowhealing<br />

wounds (43).<br />

Uses described in traditional medicine<br />

Symptomatic treatment of chronic swelling of the legs, slow-healing<br />

sprains and fractures, irritable skin conditions, gout, rheumatism, arthritis,<br />

hepatitis, fractures, sore throat, dermatological problems and haemorrhoids<br />

(44–47). In folk medicine Herba Equiseti is used as an analgesic,<br />

antihypertensive, clotting agent, haemostatic, depurative, astringent, diuretic<br />

and anti-inflammatory (48–50). In Indian Ayurvedic medicine it is<br />

used for the treatment of inflammation or benign enlargement of the<br />

prostate gland, for urinary incontinence and for enuresis in children (51).<br />

Pharmacology<br />

Experimental pharmacology<br />

Antinociceptive and anti-inflammatory activity<br />

An aqueous-ethanol extract of the stems of Equisetum arvense at concentrations<br />

of 10, 25, 50 and 100 µg/g, administered <strong>int</strong>raperitoneally, reduced<br />

the writhing induced in mice by acetic acid (49, 57, 93 and 98%, respectively).<br />

The results of treatment with the extract were positive but less<br />

marked in the formalin and carrageenan paw oedema tests, but were negative<br />

in the hotplate test. The antinociceptive and anti-inflammatory effects<br />

of the extract are thus confirmed in chemical models of nociception<br />

in vivo (52).<br />

Sedative and anticonvulsant effects<br />

In an open-field test in rats, an aqueous-ethanol extract of the aerial parts<br />

of Equisetum arvense, at doses of 200 and 400 mg/kg body weight (bw),<br />

had anticonvulsant activity. The treatment enhanced the number of falls<br />

in the rota-rod test, reducing the time of permanence on the bar. An increase<br />

in barbiturate-induced sleeping time was also observed (46% and<br />
