Mucuna pruriens in Parkinson's and in some other diseases: recent advancement and future prospective

Mucuna pruriens (Mp) is an annual and perennial legume which belongs to the family Fabaceae having different types of therapeutic activity. Anti-oxidative, anti-inflammatory, anti-epileptic, anti-microbial, etc. are the example of some most common activities of Mp. It is widely utilized as a potent aphrodisiac. The anti-Parkinsonian activity of Mp was explored since the nineteenth century. The neuroprotective activity of Mp was shown by several researchers. Levodopa (L-DOPA) is the important constituents responsible for the anti-Parkinsonian activity of Mp. Apart from L-DOPA, several other important bioactive components like Ursolic acid (UA) and Betulinic acid (BA) also exhibit a similar neuroprotective activity. Parkinson's disease (PD) is mainly sporadic. A very small proportion shows the genetic nature of PD. The anti-Parkinsonian activity of Mp was explored in different toxin-induced PD models as like MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), Rotenone, Paraquat, 6-hydroxydopamine (6-OHDA) as suggested by several pieces of literature. Various parts of Mp's like seed, leaf, and stem exhibit potent neuroprotective attributes. Among different parts, seeds are widely utilized as anti-PD agents because of the higher percentage of L-DOPA. Besides anti-PD activity, Mp's neuroprotective potential was also explored in the ischemic model of stroke that also shows positive results. Recently, several clinical trials have been performed on the anti-PD activity of Mp on PD patients that show convincing results. Although, a small population-based study needs to be further validated in the broader population. Apart from anti-PD activity, Mp also shows its therapeutic activity in some other diseases like cancer, diabetes, skin infection, anemia, antihypertensive, etc. that are summarized in Table 1. In this review, we have discussed the anti-PD potential of Mp in the sporadic and genetic model along with some clinical trials that have performed on PD patients. Some other activity of Mp is also summarized in this review. There is a strong need to test the efficacy of Mp in some other neurodegenerative diseases along with PD. Following this, this review emphasizes the role of Mp in PD systematically through literature analysis available to date
