Edible Uses

Edible Parts: Fruit Edible Uses: We have no reports for this species but the following report is for the closely related P. hexandrum. Fruit - raw. It must only be eaten when it is fully ripe[1, 2, 61, 105]. Juicy but insipid[130]. The fruit is about 5cm long[200].

Medicinal Uses

Antiphlogistic Cancer Cholagogue Cytostatic Depurative Purgative The plant is antiphlogistic and depurative[147]. The following report is for the related P. hexandrum. It quite probably also applies to this species. The whole plant, but especially the root, is cholagogue, cytostatic and purgative. The plant contains podophyllin, which has an antimyotic effect (it interferes with cell division and can thus prevent the growth of cells). It is, therefore, a possible treatment for cancer, and has been used especially in the treatment of ovarian cancer[46, 51, 57, 64, 65, 124, 244]. However, alopecia is said to be a common side-effect of this treatment[244]. This species contains about twice the quantity of active ingredient than P. peltatum[211]. The roots contain several important anti-cancer lignans, including podophyllin and berberine[218]. The roots are also antirheumatic[218]. The root is harvested in the autumn and either dried for later use or the resin is extracted[238]. This plant is highly poisonous and should only be used under the supervision of a qualified practitioner[238]. It should not be prescribed for pregnant women[238].

Known Hazards

We have seen no reports of toxicity for this species but all parts of the plant, except the fully ripe fruit, are almost certainly poisonous[K].
