Description

Wild Yam (Dioscorea) is a vine that is invasive, deciduous, and herbaceous. This species is native to Asia, though, in the U.S., it is commonly found in Florida. They can grow over 18 metres (60 feet) in length. Wild yams are an important crop, as they have been used to prevent menstrual cramps, stomach cramps, and general pain for centuries. During the 1950s scientists found that the roots of wild yams contained diosgenin which is a plant-based estrogen; diosgenin is hypothesized to aid in chemical defense against herbivores. This was used to create the first birth control pills during the 60s. In addition, some Dioscorea species are rich in nutrients and antioxidants. This is beneficial in rural areas where the plant is native because it enriches the diets of individuals who live in the area. These plants grow best near canopy gaps in woodlands and rainforests. Dioscorea uses vining behavior which is useful in tropical habitats because Dioscorea grow under canopies and need to latch onto different surfaces in order to grow upwards and acquire resources.
