Scopolia Overview
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.
Loperamide Overview
-
Nonprescription (over-the-counter) loperamide is used to control acute diarrhea (loose stools that come on suddenly and usually lasts less than 2 weeks), including travelers' diarrhea. Prescription loperamide is also used to control acute diarrhea and also ongoing diarrhea associated with inflammatory bowel disease (IBD; condition in which the lining of all or part of the intestine is swollen, irritated, or has sores). Prescription loperamide is also used to reduce the amount of fluid in people with ileostomies (surgery to create an opening for waste to leave the body through the abdomen). Loperamide is in a class of medications called antidiarrheal agents. It works by decreasing the flow of fluids and electrolytes into the bowel and by slowing down the movement of the bowel to decrease the number of bowel movements.
