Hi sosick,
when I talked about coriander in the above post I
was referring to the fresh green leaves of the plant.
We call the cilantro plant by the name coriander in Ireland &UK,
as Sunshine informed us earlier.
We definitely call the entire plant coriander over here!
(just a thought maybe it is a native american plant called cilantro,and when it arrived here,many years ago as seeds,it may have been called coriander because that is the name of the seeds!???
Anyway you said you felt ok taking it,even with amalgams.
I will probably lay off it for a while as I'm taking other things now but plan to take it at some stage...
It's tricky to know what is helping &if something is not or if remedies are maybe clashing with each other!

CAFFEINE:
In my opinion caffeine is bad news,it is such a powerful stimulant! Maybe it has it's usefull? purposes...
I have not touched tea or coffee in about 5 years.Maybe I'm allergic to it but it makes me hyperactive and euphoric,and then I crash down later,and I'm not talking one cup,I mean 2or3 sips!
CHOCOLATE,which also contains caffeine:
I went through a phase earlier this year of having 2 or 3 small squares of really dark organic chocolate,95%caocao content,same reaction ,I would be flying around &feel fantastic for about 6 HRS and feel awful the next day.
I then had 2or3 squares every day,for a couple of weeks,and ran myself into exhaustion.
I then tried to wean myself by taking a few of the pure caocao nibs(pieces of raw caocao bean)but was just kidding myself,still taking the stimulant.I went cold turkey then,and no joke the next 3 weeks or so,I was really ill,detoxing from it,apparently it's also high in copper which I also had a problem with...

An odd time I have a craving for it but vow never to go near it again,yes the good quality stuff has minerals in it but I can get them from other foods.
And the withdrawl I went through was severe enough to turn me off permanently!

I guess my advice to you if you love your coffee and you must drink but it gives you a headache,then maybe make sure
you make it weaker or have water soon enough after your coffee...?
I think that caffeinated stuff puts unnecessary pressure on the body, but that's a personal opinion!
