To quote Dr. Maldonado, from Chapter 6 of his book, Mucuna and Parkinson’s Disease: Treatment with Natural Levodopa - “To date, 50 substances have been identified in the powder of its seeds [2]. Other still unidentified components must exist in Mucuna, such as portions or mixtures of alkaloids, proteins, peptides, polysaccharides, glycosides, glycoproteins, and several phytochemicals including tryptamine, alanine, arginine, glutathione, isoquinolone, mucunine, nicotine, prurienine, serotonin, tyrosine, etc. [3].”
“These substances, identiied or not, confer special powers on Mucuna, perhaps boosting the levodopa or adding some kind of dopamine agonism and even extended its effects. We need to continue investigating them.”
