Gelsemiaceae is a small family of flowering plants primarily known for its genus Gelsemium. This family consists of a few species, which are mostly found in tropical and subtropical regions. The plants are characterized by their climbing or twining habit and produce attractive, tubular flowers that are often yellow or white. Members of the Gelsemiaceae family are notable for their medicinal properties, particularly Gelsemium sempervirens, which has been used in traditional medicine. However, some species contain toxic compounds, making them potentially harmful if ingested. Overall, Gelsemiaceae plays a role in both horticulture and medicine.
