Lathyrus Sativus
Contents
Description
Lathyrus Sativus, commonly known as Grass Pea, is a legume crop that has been cultivated for thousands of years. It is a hardy and resilient plant that can grow in poor soil conditions and has the ability to fix nitrogen in the soil. The plant is known for its high protein content, making it an important food source for many people in developing countries. However, it also contains a toxin that can cause a neurological disease called Lathyrism if consumed in large quantities over a long period of time.
