Scopalamine (also referred to as hyoscine, Devil’s Breath) is derived from one type of nightshade known as Scopolia, while the name “hyoscine” is derived from another type known as Hyoscyamus niger.
The ingestion of powdered Borrachero (South American shrub), traditionally used by indigenous cultures as medicine or entheogen, leads to hallucinations and is said to strip the consumer of it’s free will (hence the nickname Devil’s Breath). This fact however has been debunked several times in literature.
In modern day medicine scopalamine is mostly used for it’s anticholinergic properties as antiemetic drug.
