The extract of the brown seaweed Padina boergesenii and the red seaweed Hypnea valentiae was found to detoxify (in vitro) the venom of Naja nigricollis. There was a remarkable reduction in the mortality of albino mice after intraperitoneal (i.p.) administration of reconstituted venom with the extract compared to those challenged with the venom only. The survival of the animals exposed to the venom incubated with the different concentrations of the extract was used as the in vitro detoxification parameter.
