Background and purpose: Neurolathyrism is now a disease of the past and also the causative agent, Lathyrus sativus (Khesari Pulse or keerai in Local Hindi and Bhojpuri language) has now been proven to be harmless and has become part of the usual diet.
Materials and methods: The population at risk was screened and studied for demography, economic status, knowledge about Khesari pulse, awareness about so-called harmful effects of Khesari pulse intake in humans, and the effects of ban of Khesari pulse on the population which is using Lathyrus (Khesari) as a major source of pulse since the past 4 years through a questionnaire of three pages.
Results: Nearly 97% of total screened population totally fed on Khesari pulse as their major source of food and we did not found a single case of primary walking difficulty. We did find three cases of poststroke paralysis, a case of post-GBS lower limb weakness, and a case of recurrent myelitis as a part of questionnaire-based study and then followed by personally examining the patients to confirm the diagnosis.
Conclusion: Khesari pulse if consumed in smaller quantities as a part of a normal mixed diet, its nutritional values can be optimally utilized.
