    I agree, essential oils and aromatherapy seem to be the perfect complement to pheromones. Some of the nicer EO's

    are quite pricey though. Sandalwood is one of the nice ones I did splurge on. There is tons of good info on this

    forum about EO's as well. You can access it with the search function.

    Browsers and the internet itself can get finicky. Often when I get an "unable to find" or other failure, if I come

    back a while later all is fine. Although sometimes things *do* seem to screw up the browser software and I find it

    best to shut it down and start anew (sometimes just the browser, othertimes I turn off the whole system and reboot.

    Only way to totally clear out any junk in the RAM memory.)

    Me too! If you're new at it I can recommend Mindy Green's "Natural Perfumes" I just bought it from Amazon.com.

    It even has a paragraph or two about pheromones in the introduction.

    Contents go a bit like this:
    - basics of

    aromatherapy
    - blending fundamentals,
    - a review of 40 oils
    - 2 beginning blending lessons
    - 30 fragrance

    recipes
    - elemental blends
    - resource directory

    What I like about it is that she suggests blends and then

    tells you which particular oil to vary in quantity to make it suit your own taste. Proportions for fragrance

    products. EO note type and odor intensity.

    But I'm really new at it. You might already know all that stuff.



    BassMan: Thanks for the info. Learned something new today! I was somewhat mystified by that link.

    You mean there's a good chance it's not, don't you? Can we be certain?

    yeah, i also have the mindy

    green book!
    another good book is

    Per

    fumes, Splashes & Colognes : Discovering and Crafting Your Personal Fragrances

    by



    Nancy M. Booth

    a lot of informatioin on perfumery, essential oils, categories of scents and a lot more.

    worth buying if you're into personal perfumery.

    i also recently got

    Sce

    nts & Scentuality: Essential Oils & Aromatherapy for Romance, Love, and Sex (Paperback)

    by



    Valerie Ann Worwood

    and this is an excellent aromatherapy for love, sex and romance. a tons of formulas and

    recipes and what the intended results are for. it uses different angle. less concerned with perfumery and more with

    the emotional, psychological, and sensual reactions we have to certain essential oils. very very good.

    fumes, Splashes & Colognes : Discovering and Crafting Your Personal Fragrances

    by



    Nancy M. Booth

    a lot of informatioin on perfumery, essential oils, categories of scents and a lot more. worth

    buying if you're into personal perfumery.

    i also recently got

    Sce

    nts & Scentuality: Essential Oils & Aromatherapy for Romance, Love, and Sex (Paperback)

    by



    Valerie Ann Worwood

    and this is an excellent aromatherapy for love, sex and romance. a tons of formulas and

    recipes and what the intended results are for. it uses different angle. less concerned with perfumery and more with

    the emotional, psychological, and sensual reactions we have to certain essential oils. very very good.
    Hey

    thanks! I already bought Nancy Booth's book along with Mindy Green's but I haven't read it yet. I

    spent the evening last night highlighting in Mindy Green's book. V.A. Worwood's book is definitely next on my

    list. I just love the "learning curve" of new endeavors!

    Hi Madini.com is also a

    good site if you want EO's or essences. This is were I get my honeysuckle, violet and rose oils from. Their prices

    are reasonable too.

    It would probably be better to state it

    as:

    If the odorless molecule _is_ a pheromone, it's probably a quite different one from the odorous one.



    For example, the drug thalidomide - it was prescribed for morning sickness, later found to cause profound birth

    defects. One isomer controlled the morning sickness, the other the birth defects.

    Another example - vitamin E.

    The D form is active in the body, the L form inactive. Which is why synthetic E (which is a mixture of the D and L

    forms) is only half as potent as natural E (which is almost all D).

    So, yeah, I probably overstated it, but

    optical rotation usually makes a very large difference in biological activity.

    Yeah, D and L phenylalanine have

    totally different functions, both generally positive, but very different.

    So do R and S ALA. I don't

    remember which, but one is negative, one is beneficial. Together, they sort of even out into a zero sum

    game.

    With something like androstadienone, there's a definite receptor, and we know what it is (the

    vno).

    With something like androstenol, we see a physiological change in subjects, but have no idea why it's

    occuring. It's not through the vno.

    That doesn't mean that a chiral switch of pheromones can't be tested,

    however. Everyone of us here is testing mones all the time, but there's a catch with chiral forms, and that's that

    there's barely ever enough to test...

    Chiral switches are hard to get, and most known synthesis routes are

    way too costly to be ready for even a smidge of prime time. You suffer from the fact that you don't have the

    research dollars in this industry that you do in pharmaceuticals. Even those multibillion dollar companies avoided

    chiral switches for years, due to the costs of development.

    This article says that it took 15 years

    (supposedly) to get Nexium out of Prilosec. Guh! Nexium is one half the man that Prilosec is. Lots of good info
