Many fundamental errorsApril 1, 2010 Robert Tisserand(Ojai, CA) 8 out of 9 found this review helpful
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. If the book was properly referenced, this would be obvious. He also criticizes the British for "usually applying only certain compounds isolated from essential oils rather than the whole oil." It is difficult to fathom from where he plucked this outrageous notion.
There is a massive amount of information here, but there is not a single scientific reference to back up any of it. The book perpetuates the myth that any dangers of essential oils (apart from phototoxicity) only apply to what he calls "perfume grade" oils, which apparently British aromatherapists like to use. I'm not sure then, who buys all the independently certified organic essential oils sold in Britain.
Good effort, mediocre result.
cemistry of essential oils made simpleMarch 6, 2010 Ronald J. Moss 1 out of 1 found this review helpful
I wanted to find out if essential oils would do what the claims indicate. I found that essential oils have a vibration that go to the cells and receptor sites and that they only go to the sites that they are suppose to go to. A good book what answers many questions. The author does a good job explaing in laymans turms. Of oucrse not being a chemistry mjor, there were a few times I could not follow his explanaion,, overall I found the book worth the money and a good refrence guide.
Chemistry of Essential OilsJanuary 8, 2010 S. Wyatt(United States, East Coast) 2 out of 2 found this review helpful
This is an awesome educational book. Gives perspectives on YL and on many other sources in the field of E.O.'s as well as educates you on Essential Oils. Be prepared it is very educational, meaning it can get a little snoozish. But it is a Chemistry book which anyone and everyone can understand. If you aren't that interested in all the bits and pieces of this science and field maybe not the book for you. I however love it, even if I have to have coffee while reading some portions :) A great educational tool for anyone working in the field, going into the field, or wanting to educate themselves for their own personal health reasons. It is a awesome find. I was so happy to receive it for the Amazon price!
Essential ReadingOctober 8, 2009 Lorena Holmstead(Middleton, ID) 1 out of 1 found this review helpful
Having already read Essential Oils Desk Reference, I was ready for more in-depth information on how essential oils work. I found it in this amazing work by David Stewart, and it was totally entertaining and educating at the same time. I had some good Chemistry background, but he explained things so well, that one needn't have that as a pre-requisite. His perspective was one that I share, which is an understanding that God created all things, and with science, we are using only one of the tools that we have available to us to find out how natural laws work.
I couldn't recommend this book more highly. If you are going to use essential oils (and I urge you to if you are not already!), this is an absolute must-read. You will come away with both your faith and your knowledge increased. Thank you Dr. Stewart!
The Chemistry of Essential Oils Made SimpleApril 12, 2009 S. Fox(Mountain Home, AR USA) 1 out of 1 found this review helpful
This is an excellent book for people who want to know why Therapeutic Grade Essential Oils are so effective. It explains how they work and how to understand which oils will be effective for each specific problem. It's a well written book, clearly written by a master of the art of Essential Oils and the science of chemistry.
