Conservation status
The species is quite common, but has not yet been evaluated for the Red Data List
(Von Ahlenfeldt et al., 2003). However, the destruction of its habitat due to
mismanagement of the wetlands, and uncontrolled harvesting for the medicinal trade
market, are the main threats to the survival of Gunnera perpensa.
Medicinal uses
In South Africa, a decoction of the roots of Gunnera perpensa is used to induce
labour, expel the placenta after birth or to relieve menstrual pains and as an
antenatal medication to tone uterus, treat stomach trouble, rheumatic fever, swelling
and stomach bleeding. It is applied externally for the dressing of wounds for
psoriasis (Ngwenya et al. 2003; Van Wyk et al., 1997; Von Ahlenfeldt et al. 2003).
Data from ethnobotanical survey
The roots are boiled with water and the resulting mixture is drunk, depending on the
condition of the sores of the person (Ngema 2007, pers. comm.).
Chemical content
Little is known of the chemistry of this species. The occurrence of a bitter principle
named celastrin has been reported (Benson & Margulis, 2002).
