Different concentrations of latex were used in mortality tests with several aquatic animals. The latex was found to be a short-lived and effective fish poison. Within 12 hours all the fish and half the frogs died, whereas crabs and snails appeared not to suffer any detrimental effects. The poison degraded and became harmless to fish within 48 hours[

The latex and roots contain ingenol, a tetracyclic diterpene ester of the ingenane type, based on the parent alcohol 16-hydroxyingenol and several derivatives. Ingenol and its derivatives show tumour-promoting, anti-HIV and anti-leukaemia activities. Much research is directed toward synthesis and biological evaluation of ingenol analogs and derivatives. The irritant ingenol esters of the latex have ID50 values of 0.004 - 0.02 μg in mice-ear tests.[
