Mucuna pruriens to treat Parkinson's disease in low-income countries: Recommendations and practical guidelines from the farmer to clinical trials. Paving the way for future use in clinical practice.

Parkinson's disease (PD) is a progressive and disabling neurodegenerative disease that rapidly worsens and results in premature mortality if left untreated. Although levodopa is the gold standard treatment for PD globally, its accessibility and affordability are severely limited in low- and middle-income countries worldwide. In this scenario, Mucuna pruriens (MP), a leguminous plant growing wild in tropical regions, emerges as a potential alternative or adjunct to levodopa-based medications due to its cost-effectiveness and global natural availability. Recent studies have demonstrated that MP can significantly ameliorate motor symptoms, although tolerability may vary. The proposition that MP could play a pivotal role in providing affordable and symptomatic relief for PD in low- and middle-income countries is grounded in its promising therapeutic profile, yet caution is warranted until more comprehensive data on the long-term safety and efficacy of MP become available. This manuscript summarizes the knowledge gained about MP by the authors, focusing on how to cultivate, store, and provide it to patients in the safest and most effective way in clinical trials. We aim to increase clinical trials investigating its safety and efficacy in PD, before promoting individual use of MP on a global scale, particularly in countries where availability and affordability of levodopa-based medications is still limited.
