Scopolia Overview

Scopolia Scopolia is a plant genus that belongs to the Solanaceae family, which also includes tomato, potato, and tobacco. There are several species of Scopolia plants, including Scopolia carniolica, Scopolia japonica, and Scopolia tangutica. These plants are native to Asia and Europe and are known for their poisonous properties as they contain several dangerous alkaloids, such as L-hyoscyamine, atropine, and scopolamine, all of which are strong anticholinergics. These alkaloids have well known medicinally properties and are even available as prescription drugs to treat a variety of conditions, including motion sickness and spasms of the gastrointestinal (GI) tract. However, scopolia is generally considered unsafe when used for self-medication and should only be used under the supervision of a healthcare professional.
