Many of the ingredients can be obtained in NYC, in small storefronts that sell dried herbs, spices and essential oils and other materials used in the book's recipes. Enchantments on East 9th Street and Enfleurage on Bleecker Street are good sources. Stepping into those places is like being transported into another time; one diametrically opposed to multitasking or speeding along in any way.
Here is a quote from page 26 about the use of perfume in the Middle East, that speaks of living in a fragrance induced state of dreamy languor:
"The oriental ladies use great quantities of costly
perfumes and cosmetics, and the duties of the toilet
are their most important occupation, no doubt tend-
ing to preserve their personal charms. Living in an
atmosphere of fragrance, they are kept in a state of
dreamy languor, which to them may be the nearest
approach to happiness. They are noted for their
skill in retaining their charms by these various means.
