Please read before use: the information below describes traditional and informational uses—it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: Avoid all use during pregnancy and breastfeeding, due to traditional use related to the female cycle that is insufficiently documented and potentially risky. Do not administer to young children without the advice of a qualified healthcare professional. Strictly observe dosages, as the plant may cause digestive irritation at high doses. Seek the advice of a healthcare professional if taking medication, particularly diuretics.

Decoction — Dried Root

Traditional root decoction

The dried and cut root was gently boiled in water for about fifteen minutes, then filtered before consumption. This preparation, the most common in the eclectic tradition, must be established with the assistance of a professionally trained herbalist, as the precise dosage is not reliably documented. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Tincture — Fresh or Dried Root

Root tincture

The root was macerated in alcohol for several weeks to obtain a concentrated tincture, a use traditionally reserved for experienced practitioners. As the dosage must be adjusted on a case-by-case basis, it cannot be indicated without qualified supervision. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
