I agree about getting the powders from individual suppliers selling
what might appear to be the same henna powder is very important.
What you stated is what would make getting it from the place of
origin a problem. Too much problem with possibility for cross
contamination is some way. I think also in matters of whether or not
a supplier wishes to sift the henna powder they get from an exporter,
this would make the henna powder also look different under the
microscope from the powder another supplier decided to sell "as is."
So what does this mean in terms of how powders are identified on a
list. Is it identified just by the name of the henna powder, by the
supplier and the name of the henna powder? What happens when powders
come from all over the place though is the same thing that occured
with the second test. It really goes through too many hands and
can't be controlled for reliability.
