Lathyrus pratensis

Safety & Hazards

Although no specific records of toxicity have been found for this species, the seed and other parts of many Lathyrus species contain a toxic amino acid. It is produced in the plant at about the same time that the seed starts to develop. In small quantities the amino acid is innocuous, and the seeds of several Lathyrus species are eaten as a nutritious part of the diet. However, in larger quantities (the seed should form less than 30% of a balanced diet), it can cause a very serious disease of the nervous system known as 'lathyrism'. Symptoms appear as a paralysis of the muscles below the knees, pains in the back, followed by weakness and stiffness of the legs and progressive locomotive incoordination[ 65 Title A Colour Atlas of Poisonous Plants.
