Are Chinese lantern flowers poisonous

Yes, Chinese lantern flowers (Physalis alkekengi) are considered toxic. The plant contains solanine, a toxic alkaloid that can cause symptoms such as nausea, vomiting, and diarrhea if ingested. While the ripe fruit is sometimes used in culinary applications, it should be handled with caution, as unripe fruit and other parts of the plant are more toxic. It's best to avoid consuming any part of the plant without proper knowledge and preparation.
