What is discorea mexicana?

Discorea mexicana, commonly known as Mexican Yam or Barbasco, is a species of perennial herbaceous plant in the family Dioscoreaceae. It is native to Mexico and is commonly found in mountainous regions.

Mexican Yam has large, heart-shaped leaves that are glossy green in color. The stems are long and twining, and the plant produces small white or yellowish flowers that bloom in the summer.

The root of the plant, known as Barbasco, has been historically used by indigenous people in Mexico as a fish poison and as a treatment for snake bites. It contains a compound called diosgenin, which is used in the production of hormones such as estrogen and progesterone.

Mexican Yam is also used in traditional medicine for its anti-inflammatory and analgesic properties, as well as for its ability to lower blood sugar levels. However, more research is needed to fully determine its efficacy and safety as a medicinal herb.

The plant is cultivated commercially for the production of diosgenin and is also used as a food source. The starchy roots are boiled or roasted and eaten like potatoes.
