Oenanthe is a genus of flowering plants in the family Apiaceae, commonly known as water dropworts. These plants are typically found in wet habitats, such as marshes and riverbanks, and are characterized by their hollow stems and small white flowers. Some species are known for their medicinal properties, while others can be toxic if ingested. The genus includes several species, with Oenanthe crocata being one of the most notable due to its high toxicity. Oenanthe plants are often used in traditional medicine, but caution is advised due to the potential risks associated with certain species.
