Mucuna pruriens is a tropical legume native to Africa and tropical Asia and widely naturalized and cultivated. [2] Its English common names include monkey tamarind , velvet bean , Bengal velvet bean , Florida velvet bean , Mauritius velvet bean , Yokohama velvet bean , cowage , cowitch , lacuna bean , and Lyon bean .

Mucuna is a genus of around 114 accepted species of climbing lianas (vines) and shrubs of the family Fabaceae: tribe Phaseoleae, typically found in tropical and subtropical forests in the Americas, sub-Saharan Africa, southern, southeastern, and eastern Asia, New Guinea, Australia, and the Pacific Islands.
l-DOPA, also known as l-3,4-dihydroxyphenylalanine and used medically as levodopa, is made and used as part of the normal biology of some plants [2] and animals, including humans. Humans, as well as a portion of the other animals that utilize l -DOPA, make it via biosynthesis from the amino acid l -tyrosine .

Tyrosine hydroxylase or tyrosine 3-monooxygenase is the enzyme responsible for catalyzing the conversion of the amino acid L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA). [5] [6] It does so using molecular oxygen (O 2), as well as iron (Fe 2+) and tetrahydrobiopterin as cofactors.
However, when consumed as a botanical extract, for example from M pruriens supplements, a peripheral DOPA decarboxylase inhibitor is not present. [ 8 ] Inbrija (previously known as CVT-301) is an inhaled powder formulation of levodopa indicated for the intermittent treatment of "off episodes" in patients with Parkinson's disease currently ...
Mucuna monosperma, commonly known as negro beans in India, or deer-eye beans, donkey-eye beans, or ox-eye beans, is a large woody climber from the family Fabaceae. [2] The plant has three layers; a brown pod covered in small hairs, curved petals usually colored purple and black round-shaped beans.
L-DOPA is transformed into dopamine in the dopaminergic neurons by dopa-decarboxylase. [3] Since motor symptoms are produced by a lack of dopamine in the substantia nigra, the administration of L-DOPA temporarily diminishes the motor symptoms. [3] Only 5–10% of L-DOPA crosses the blood–brain barrier.
