How does Lathyrus work?

There isn't enough information to know how lathyrus might work for any medical use.

Are there safety concerns?

Lathyrus is LIKELY UNSAFE when taken by mouth. It is poisonous to nerves. It can cause muscle rigidity, muscle spasms, weakness, paralysis of leg muscles, weak heartbeat, decreased breathing, seizures, and death.

Lathyrus poisoning and its complications are rare in western countries, yet they have been documented for more than a century in Europe, Africa, and Asia. Despite the attempt to ban the sale of Lathyrus sativus in several states of India, distribution continues. To deactivate the poison, several methods have been tried. Typically they involve soaking the seeds in water followed by steaming or sun drying. Roasting the seeds at high temperatures for twenty minutes also helps to destroy the poison. However, these methods are only 80-85% effective.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It's LIKELY UNSAFE to use lathyrus because it contains poisonous chemicals. Avoid use.
