Nightshade plants (Solanum spp.) are not commonly found in Nepal, but some species may be found in the subtropical and tropical regions of the country. These plants are known to contain toxic alkaloids, which can be dangerous if ingested or even touched by humans or animals.
One of the most dangerous species of nightshade found in Nepal is the deadly nightshade (Atropa belladonna), which contains atropine and other toxic alkaloids. Ingestion of the plant's leaves or berries can cause symptoms such as dry mouth, blurred vision, dizziness, confusion, and even death in severe cases. Another species of nightshade found in Nepal is the bittersweet nightshade (Solanum dulcamara), which is known to contain solanine and other alkaloids. Ingestion of the plant can cause symptoms such as nausea, vomiting, diarrhea, abdominal pain, and fever.
It is important for tourists and hikers to be aware of the dangers of these plants and avoid ingesting or touching them. If accidental ingestion or contact occurs, it is recommended to seek medical attention immediately.
