I could not find a specific medical definition for "Cyclea." However, Cyclea is a genus of flowering plants in the family Menispermaceae. It includes around 50 species of woody vines and shrubs that are native to tropical regions of Asia and Africa. Some species of Cyclea have been used in traditional medicine in various parts of the world. For example, in Ayurvedic medicine, the root of Cyclea peltata is used to treat a variety of conditions, including skin diseases, menstrual disorders, and digestive problems. However, it's important to note that the use of these plants as medicines should be done under the guidance of a qualified healthcare provider, as they can have side effects and interact with other medications.
