In reply to: Terpenes vs. Cineole posted by Stacey on October 20, 2002 at 19:44:46:

Though I've always been fond of cineol/e, I've been having this
feeling that perhaps it isn't so much one single terpene, as a
combination of types of terpenes. The oils we use seem to be high in
alcohols and we've narrowed down the oils that seem to work the best.
Throw in the oxide cineol/e or rather, the 1,8 cineole and we've got
amazing results. Thus, perhaps it is the alcohols and oxides reacting
with each other and/or/then acting on the henna. I'm with Catherine
on thinking it isn't just one single chemical because the variables
for the oils is so vast- consider Eucalyptus- that we really never
know for certain what percentage we are dealing with, but we know
some certainties in that a particular type of terpene is higher in
say, Tea Tree in general than any given variety of Eucalyptus in
general. Besides that, Rosemary is the primary candidate on 1,8
cineole and I don't think it has ever demonstated the results that
Tea Tree consistently does.

: Okay, here I am again, about to embark on another, I'm sure, boring
: discussion of chemistry. Thank you all for the fabulous dialogue
: terpenes and your opinions on which oils slam that stain into the
: skin the best. I looked up in my essential oils chemistry book
: ("The Aromatherapy Practitioner Manual" by Sylla Sheppard-Hanger of
: the Atlantic Institute of Aromatherapy in Tampa, from whom I
: learned) the oils tea tree (melaleuca alternifolia), cajeput
: (melaleuca cajuputi), cardamom (elletaria cardamomum), and two
: species of eucalpytus (globulus and radiata), and the common
: denominator is 1,8 cineole, all oils containing over 85% (except in
: the case of eucalyptus radiata which could contain as little as
: 63%). So it looks like we are needing 1,8 cineole in our blends.
: Other oils containing high concentrations of 1,8 cineole are
: galangal, hyssop, roman chamomile, blue and white yarrow (milfoil),
: spike lavender, allspice, French and Bulgarian rose absolute
: (expensive!), and turmeric and spearmint which contain about 6-10%
: (but if you want to cover the icky smell of the melaleucas or
: eucalpytus you can use some of these others).
: I have had fabulous luck this week with tea tree (thanks!) and pink
: grapefruit (on me) and look forward to making batches with some of
: these other oils. I have the Withlacoochee River Bluegrass
: to do on 11/2, and now I am not worried about people getting a good
: enough stain (I was worried about that at my first show).
: Regarding a place to get the oils, I sell them at my website and I
: give a 20% discount to professionals (mostly health professionals
: but I certainly consider henna artists professionals since they use
: the oils consistently). Please stop by and sign in and I'm sure if
: there's something you want, I can get it for you cheap (well
: than retail!).
: Thanks guys!
