 No definitive antidote is available , but some specific treatments have been shown to improve survivability . High @-@ dose continuous intravenous penicillin G has been reported to be of benefit , though the exact mechanism is unknown , and trials with cephalosporins show promise . Some evidence indicates intravenous silibinin , an extract from the blessed milk thistle ( <unk> <unk> ) , may be beneficial in reducing the effects of death cap poisoning . A long @-@ term clinical trial of intravenous silibinin began in the US in 2010 . <unk> prevents the uptake of amatoxins by liver cells , thereby protecting undamaged liver tissue ; it also stimulates DNA @-@ dependent RNA polymerases , leading to an increase in RNA synthesis . According to one report based on a treatment of 60 patients with silibinin , the patients who have started the drug within 96 hours of ingesting the mushroom and who have still had kidney function intact have all survived . As of February 2014 supporting research hasn ’ t yet been published .
