Mucuna is a revered herb of India, where it is known as velvet bean. It has been known to have potent libido and mood-enhancing properties due to its effect on dopamine levels in the brain. Dopamine is a neurotransmitter, which, like serotonin, regulates mood. Mucuna has traditionally been used to treat seizure and nerve-related ailments and may be effective in treating depression and low libido. In modern times it has been used as a supplement to rebalance brain chemistry after indulging in alcohol and other drugs.
