Nearly 2,000 geezerhood ago , someone used a core out - out piece of ivory as a container for storing century of poisonous seeds .

archeologist found the chip at - out animal femur , or thigh pearl , which likely came from a goat or sheep , at Houten - Castellum , a ruralRoman - period settlement in what is now the Netherlands . Prior to this discovery in 2017 , there had been no physical grounds of this plant being used by people in the Roman Empire , according to a statement .

The hollowed-out animal bone was used to store poisonous seeds during the Roman era.

The tiny seeds come up from the black henbane ( Hyoscyamus niger ) , a extremely venomous plant from the nightshade family . black henbane has long been prized for its medicinal properties and hallucinogenic consequence , harmonise to a fresh study , bring out in the April issue of the journalAntiquity .

research worker have found similar seedsscattered at archaeologist sitesacross Europe dating back to 5500 B.C. However , it ’s often challenge to determine whether the presence of black stinking nightshade at these sites indicate it was used or come out naturally , as the plant develop like a weed .

" Since the plant life can grow course in and around settlements , its seeds can end up in archaeological sites naturally , without intervention by humans , " study jumper cable authorMaaike Groot , a zooarchaeologist at the Free University of Berlin , said in the statement .

" The discovery is unequaled and provides patent proof for the intentional use of smuggled Hyoscyamus niger seeds in the Roman Netherlands , " Groot enjoin .

The seeds support early classic literature claiming that black henbane was used during the Roman flow — although these sources suggest it was used medicinally and was n’t considered a recreational drug , accord to the survey . For instance , papist author and naturalist Pliny the Elder ( who lived from A.D. 23 to 79 ) wrote that the seeds could get " insanity and giddiness , " according to the study .

" Our subject field contributes to the discussion of how to separate between a smoke naturally ending up in archaeobotanical assemblages and a plant intentionally used by people , " Groot allege . " We argue that future find of black henbane should be contemplate by look at into account the context of the find and its relation back to other medicative plants . "
