What
: do you guys mean when you say "terp"-ing? Are you adding oils that
: are supposed to contain terpenes (or monoterpenes)?

Yep.

If that's the
: case, I have been reading that people use cardamom and cajeput to
: terp their paste? Well, if you are interested, cardamom only
: contains 6% terpenes and cajeput (member of the melaleuca family)
: contains less than 10%. My friend, a fellow aromatherapist, and I
: have been using just plain ol' Indian-store Mumtaz henna with oils
: that contain 85-95% terpenes and are getting fantastic stains that
: last weeks (with very short light orange periods). In our
: aromatherapy manuals we have found that the oils that contain the
: highest terpenes are most citrus oils (especially pink grapefruit
: and sweet orange) and the pines (mostly Siberian fir needle) (I
: would not recommend using the pines since many people experience
: allergic reactions and most people get along well with the citrus
: oils).

The citrus oils have difficulties with being out in the sunlight. I
believe the term is "phototoxic". I'm not sure exactly what they do,
but once people start using words like "vomiting" and "rash", I look
elsewhere.
The terp levels in cardamom, cajeput, ravensara, and certain
eucalyptuses, among others, are quite enough for our purposes.
besides, I LOVE the smell of cardamom paste!

My main recipe is to use lemon juice for the main
: constituent, then pink grapefruit, sweet orange or lime (2 or 3
: different ones).

I know that lemon oil and citronella are unfriendly when exposed to
sunlight. I don't know the relative values of each of these oils but
what's true for lemon is usually true for lime. I think Orange is
okay, but I wouldn't swear to it.
