Since this thread is showing signs of life and causing my esteemed colleague Soccertese to take interest, I will briefly stir things a little.

Mucuna has a complex structure of over 400 individual substances. These include a number of amino acids and vitamins and minerals that offer a real "toolkit" for the repair of body systems. The hypothesis is that the varied material available is going to increase the repair speeds and quality. The sinamet, on the other hand is a highly purified single ingredient and is not comparable to the other. At this stage, we really don't know the truth so it becomes a matter of belief. I believe that there is enormous power in the possible synergies between those ingredients.

We seldom hear it discussed, but there is a concept in science of "elegance" and "beauty" as spooky pointers to "truth". It is usually used by physicists, the "mad monks" of science, but members of other disciplines have been found, their lifeless bodies slumped over their Big Chief Composition Tablets and their cold, dead fingers gripping their oversized Dixon Crayons as they have scrawled cryptic phrasing such as "My gawd that is ...." before slipping this mortal coil.
(Damn! I almost started a Fukushima Reaction there for a moment.)

<The turbulence has now passed and we will resume flying in just a moment. Thank you for flying with the Mother Ship Connection. >

And I feel that the idea of groups evolving together to their mutual benefit is both beautiful and elegant and, therefore, closer to truth than the primitive. About time to pass out the P-Funk. <If you don't know then you'll never understand, but I woke up this morning wearing Bootsy Collins's underwear!>

<And Keith Richards remains at large so far as anyone can tell....and Lou Reed is dead....>

Bob! Moondaughter! Get me outta here!
