Abstract:
From the results of experiments conducted upon fourteen rabbits it appears that repeated ingestion of small amounts of slangkop does not induce the development of tolerance but that the plant has cumulative effects. What has been said about gifblaar (Steyn, 1934) in this repect, is also applicable to slangkop.
As the active principle of slangkop belongs to the digitalis series the above findings are not at all surprising.
