If you're sensitive to those dyes .... they make you itchy prickly and
your life miserable. The worst of the azine lot is PPD. Others are
those artificial *acceptable* for food color dyes that give some
children fits.

The green may irritate some people .. my gripe is "why put that sh*t
in there in the first place except to raise your profit margin".
Here's the published scientific paper I found on the stuff:

"Study of Quality Characteristics of Henna", Chourasia, Sardar, Patil,
Mathew,Kanpur, India: Essential Oil Association of India, 1989

"Major contaminants /adulterants in henna leaves are stems, dirt,
plant waste and other leaves. However in case of henna powder
admixture of dyed sand is observed. It shas been reported that for
adulteration, finely ground local sand is used. It is first dyed with
auramine yellow (C.I. No. 41000) and then green with diamond green
(C.I. No. 20440). This is then mixed with pure henna powder. The
extent of adulteraion is viariable in accordance with the price of the
powder reflected therein.

"Added azo dyes were not found in henna leaf samples, but yellow and
green coal tar dyes were observed in powdered samples. As mentioned
earlier, this may be due to the presence of (the afore mentioned dyed
sand). Unlike Lawsone, the natural color of henna, these added
synthetic azo-dyes used for dyeing the sand or for polishing the
leaves may have an adverse effect on the skin. It is, therefore,
necessary to ensure that these artificial dyes are not there in the
product marketed.

Does it irritate you that this stuff is dumped in nearly every Indian
henna just to make it more profitable, when there is a clear call to
stop the practice? THere's so much of it in the cooperative mills
that if one person processes their henna with that damn green sand,
the next several people in the que end up with that crap in their
henna too!
