Hyoscyamines
Hyoscyamines are a group of natural substances found in certain plants, particularly in the nightshade family. These compounds are known for their anticholinergic properties, which means they can block the action of the neurotransmitter acetylcholine in the nervous system. Hyoscyamines are commonly used in medicine to treat various conditions such as overactive bladder, irritable bowel syndrome, and certain gastrointestinal disorders. They work by relaxing smooth muscles and reducing muscle spasms in the body.
