Levodopa, which is extracted from Velvet Bean, is the most effective medicine for relieving symptoms of Parkinson's disease. It helps reduce tremor, stiffness, and slowness and helps improve muscle control, balance, and walking. It does not affect freezing, dementia, or problems with involuntary (autonomic) functions, such as constipation, urinary problems, impotence, or pain.
Levodopa is a medicine that the brain converts to dopamine. Carbidopa is a medicine (called a decarboxylase inhibitor) that, when taken with levodopa, helps prevent the levodopa from converting to dopamine outside the brain.
