I got interested in EOs for the 2nd time in my life a few months ago. The first time, I guess I just "spun out" because I couldn't get a handle on them. This time I was reading, reading, reading, ordering books here on Amazon to gain more information about EOs and it seemed like every oil was good for everything, so I decided it was time to find a class or conference or seminar or something to help me sort through everything.
Thanks to Google, I found one about 100 miles from my home and only a couple of weeks off. The site I found was [...] and David and Lee Stewart are the owners of that website. They listed several seminars on their site - most of which were taught by some of their students, but the one coming up close to me was going to be taught by David and Lee, themselves. I'm thinking this is what I need to do - so I signed up. Two of the books which David wrote were part of the curriculum for the weekend event, so I went ahead and ordered them from Amazon so I could read them before the class. The other book, EOs of the Bible came and I was able to read most of that, but this book, the Chemistry book was on back order. They (the Stewarts) had copies of the book for students to use at the Seminar, so I got to have a book in hand while many references were made to the chemical aspects of EOs.
Okay, I'm not a chemistry student - never had a class in it in my life (how'd I manage to escape that, I have to wonder), so only a few terms were familiar to me, but the class - and also this book - made it clear. He could have named the book EO Chemistry for DUMMIES - and it would have worked for me. The book simplifies the chemical makeup of EOs and makes the "chaotic world" (my words) of EOs simple (ok, simpler) - and you begin to make sense of it all.
David Stewart has degrees in mathematics, physics, and geophysics, but apparently not chemistry, and this book is replete with errors. There are innumerable mis-spellings of the names of chemicals. Saponins do not occur in essential oils, nor do tetraterpenes, and there are simple, basic chemical reasons for this. Terpinen-4-ol is an alcohol, not a phenol, a blunder that most aromatherapists would spot, and bergamotene is a terpene, not a furanocoumarin. Stewart has clearly copied mistakes from other sources, without realizing they were mistakes. l-Limonene is quite often given instead of d-limonene, and methyleugenol has curiously disappeared as an essential oil constituent altogether - it's not mentioned in any of the oils it is actually found in. Furanocoumarins are frequently cited that may indeed be present in the plant but are not found in the essential oil.
Stewart has made a valiant effort to list the components of 113 essential oils, but the method he used - combining data from various books - is highly risky. The end result is said to represent a "typical" essential oil, but is rather hit-and-miss, and in many cases does not represent any existing essential oil at all. Some of the total percentages add up to more than 100%.
Stewart is highly critical of what he calls the "British School" of aromatherapy, because it espouses the idea that some essential oils can be dangerous, and because, according to Stewart, it relies "on scientific research on animals". However, he does take on board the idea that some furanocoumarins are phototoxic. He perhaps does not realize that phototoxicity in essential oils is almost entirely based on RIFM research using pigs and much of the "French" information about essential oil constituents that Stewart cites is based on animal research.
