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: Plant contains cardiotonic glycosides similar to those found in foxglove: never use without supervision by a healthcare professional trained in herbal medicine. Contraindicated in pregnancy, breastfeeding, in children, and in anyone receiving cardiac treatment (risk of serious interaction, particularly with digoxin and other cardiotonics). The margin between traditionally used dose and toxic dose is narrow; overdose can cause serious cardiac disturbances. Fresh latex may irritate skin and mucous membranes; avoid all contact with eyes.

Decoction — Dried root

Traditional root decoction

The dried and cut root was traditionally simmered gently in water, in very small quantities, reserved for occasional and supervised use. This preparation should only be considered after consultation with a healthcare professional or qualified herbalist, due to the potency of the plant. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Tincture — Dried root

Root mother tincture

Professional guidance is essential before any use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Compress — Latex or crushed root

Topical application to skin

The milky latex or a moistened root paste was applied externally and locally to stubborn skin lesions, avoiding any contact with healthy areas or mucous membranes. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
