Is velvet bean capsule good for a person diagnosed with parkinson's syndrome?

Unknown, uncertain: Velvet bean extract is in some products (in uncertain amounts), but since they are not medications approved by the fda, the products are probably not tested for interactions with medications such as parkinson's meds. So, that means nobody really knows what effects or interactions there are. If an velvet bean "product" user thinks he is getting an interaction, he can visit his primary care doctor.
