There are those materials that are genuinely found in nature or are made from naturally occurring raw materials. We decided that any material that did not occur exactly in the named form would be removed from the main body of the text and added to a "nearly natural" Appendix at the end of the volume (e.g. Potassium Sorbate, Sodium Palmate, etc.)This is an eBook, which means that if you have a Kindle reader it will index the whole book and make it totally searchable. If you have it on a laptop or PC then it is still able to be interrogated for answers. There are about 2,600 entries, we have more than one entry for a number of plants materials because we have differentiated between the fixed oil, the essential oil, the root extract, the leaf extract or fruit because they have different chemistry and differing uses.
