The acute LD50s of ferulenol were determined in albino mice by single po or ip as 2,100 and 319 mg/kg bw, respectively. Ferulenol had a higher LD50 compared to warfarin and thus has a lower acute toxicity. Three days after ferulenol administration, dosed animals showed hypoprothrombinemia with internal and external hemorrhages similar to those described in ferulosys and anti-vitamin K experimental poisonings. Male mice were more sensitive to intoxication by ferulenol than were females.
