Diuretic Purgative
The root is diuretic, emetic and purgative[1, 4, 46]. A resin is extracted with alcohol from the bark of the root[4]. The plant has been considered specific in treating pain, though caution is advised since it is poisonous to some mammals[4]. The plant is also strongly rubefacient, producing blisters and intense itching[4].

Cultivation details
We have very little information on this species, it probably requires a well drained light fertile soil in a sunny position. One report says that it is not hardy in Britain requiring greenhouse or half-hardy treatment[1]. We have grown it in the past in Cornwall, it survived 3 winters in a cold greenhouse with us before succumbing to slugs.
