Anyone heard of DopaTropic?

My GP told me about a herbal supplement called DopaTropic, which is apparently a natural source of L-Dopa, but with less side effects. Seems too good to be true. Does anyone know anything about this, or has anyone tried it?
here is a surprising and interesting article

they used 30g per day which is a lot of beans!
Sounds like a tropical island.....I wish!!

thanks turnip, that is interesting but dates from. Any idea if further research was completed?
not that i know, woder if the nicotin in the beans helps?
