Hyoscyamus niger, commonly known as henbane, contains potent alkaloids that can cause anticholinergic toxicity when ingested. This case report describes a 35-year-old male gardener who presented with confusion, hallucinations, dry mouth, and dilated pupils after consuming parts of the plant. The patient was treated with rehydration, activated charcoal, and physostigmine, leading to rapid clinical improvement. This case highlights the importance of recognizing plant-based poisonings and the efficacy of physostigmine in managing anticholinergic syndrome. Public awareness and education on the dangers of unfamiliar plants are essential to prevent accidental ingestions.
