Hyoscine, also known as scopolamine, is a medication derived from the henbane plant. It is primarily used to treat motion sickness and to help with nausea and vomiting. Hyoscine works by blocking certain signals in the brain that trigger these symptoms, making it effective for travelers and those undergoing surgery. In addition to its use for motion sickness, hyoscine can also be used to relieve muscle spasms in the gastrointestinal tract. It is available in various forms, including tablets, patches, and injections, allowing for flexible administration depending on the patient's needs.
