Mucuna pruriens
Also known as Velvet Bean. Mucuna pruriens is used in Ayurvedic medicine as an aphrodisiac and treatment for nervous disorders. Velvet bean is used as an alternative treatment in Parkinson’s Disease, as it’s high in l-dopa, the precursor to the neurotransmitter dopamine.
Mucuna pruriens allegedly increases growth hormone output, although this claim (which appears in a patent) needs to be substantiated.
