Nutmeg

One study has shown that the compound macelignan isolated from Myristica fragrans (Myristicaceae) may exert antimicrobial activity against Streptococcus mutants, but this treatment is no longer used. Nutmeg has been used in medicine since at least the seventh century. In the 19th century it was used as an abortifacient drug, which led to numerous recorded cases of nutmeg poisoning.
