Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - There are several species of plants that contain tropane alkaloids consisting of atropine, scopolamine, and hyoscyamine compounds. Given the effect on the pupils with mydriasis, these are known as the belladonna (beautiful woman) alkaloids. Jimson weed species (Datura spp.) are the most well-known plants that contain these alkaloids. Ingestion may occur through the drinking of tea made from the leaves or flowers of the plant or from eating the plant’s seeds or leaves. Poisoned victims demonstrate an anticholinergic toxidrome resulting from the antimuscarinic receptor antagonistic effects of atropine and scopolamine. Patients may exhibit altered mental status, xerostomia, xeroderma, xerophthalmia, blurred vision, mydriasis, tachycardia, decreased bowel and bladder motility, and hyperthermia. Occasional presentations of unilateral mydriasis occur from topical exposure of the alkaloids (usually by touching the plant and then the eye).
