I have this book, and sometimes refer to it.

Dr. Duke has a website too, with the ingredients of many plants listed.
It is amazing.

He claims that many compounds are absorbed into the body and circulation
from essential oils. He gives an example of Lavender oil... that it can be smelled on the breath minutes after application.

His book however is sparse on oils.

He has a wonderful database tho:

I find it quite amazing that all those compounds are in geranium oil!

iherb even has it by NOW company:

Dang I just got my order for the next 3 mons... but I will put this on my list
for when I get back from the summer...and give it a try.

Thanks for the input, Marlene.
I guess it is important to use the Pelargonium graveolens form... since I did find other types
on the net during a brief search.
(as an aside... I am not a big fan of geraniums... I avoid them as plants in the garden. So I guess I'll have to
buck up on that issue!)
