I think that you are just overcautious, Ed. Have you got any reason to doubt
that a small amount of dietary noradrenaline as in purslane would do any
harm? Any studies or references?
You know that it is "a small amount"? The study I posted says
"High concentration of (-)-noradrenaline in Portulaca oleracea L."
I don't think there's much doubt that noradrenaline, dopamine can kill.
There seem to plenty of such references on the web in the conduct of
research. It seems to be taken as a point of fact rather than a
question.
The question remains, how much noradrenaline, dopamine etc is there in
purslane?
Quoted message said:Purslane is a classic salad vegetable used
in the whole Eastern Mediterranean area.
and that proves that it isn't responsible for unneccessary deaths?
At one time, opium was a classic smoke in parts of Asia, tobacco
remains popular today. By your 'logic' that makes these something
to recommend?
Quoted message said:I think that for most of people a small amount of dopamine and noradrenaline
in purslane is just beneficial as they are mood enhancing neurotransmitters.
Do you have any reason to think that?
If there's enough to have a measureable beneficial effect for some,
then its likely to be a problem for others. I find it odd to think
it is "just beneficial". Is this some kind of herbal magic where its
friendly spirit stops absorption in individuals who would be harmed?
While dopamine and noradrenaline clearly can do other things.
dopamine from purslane does not reach the brain (see below)
so it will not effect mood, it can raise BP if there's a
sig. amount there.
Purslane contains excitory neurotransmitter chemicals.
Those who might be sensitive ought start with a small 'dose'.
Those on MAOI drugs ought to avoid it entirely per my first
reference link below.

I know that you are being flip but there's a point or two here:
Fava beans (part of that same meal) are another middle eastern
functional food. Heavy on levadopa which is a dopamine precursor
(which you ingest directly from purslane), favas are considered a
"treatment for Parkinson's but they are also dangerous to some.
Benefit and danger described here:
http://www.parkinson.org/site/pp.asp?c=9dJFJLPwB&b=100110
Note the widely varying levadopa content in the beans.

http://www.lef.org/anti-aging/chap9.html
purslane will not improve mood since the dopamine dosn't cross
the BB-barrier (except to cause nausea & vomiting if you can get
that much), it will affect the heart. (ref the lef link)
purslane will help you tolerate fava, (ref the lef link)
clever menu planning at the white house!
Clearly, foods can be dangerous despite being popular
in some parts of the world.
Tangential point:
You don't really think that Billy Bob had some part in
planning the meal? I suppose he selected opera for the
entertainment.
