Material Review: Clary Sage Oils
Variation in composition and enantiomeric analyses of commercial vs. new Kashmir clary sage oils. Commercial clary sage oils were analyzed along with a newly available Kashmir oil (Himalayan Foothills Oils, Srinagar, India). All of the oils were high in linalool (14.7–25.1%) and linalyl acetate (55.0–72.4%).

Aromatherapy: Do Essential Oils Have Therapeutic Properties?
A pleasant odor has always been, and still is, an important factor for people to feel good, and feeling well is synonymous with good health. Therefore, we can conclude that all substances which are able to create a certain amount of well-being and well-feeling possess therapeutic properties and, therefore, can be called therapeutic agents.

New compounds with small rings in essential oils
Despite the continuing discovery of new synthetic fragrance raw materials, essential oils still remain the other half of the foundation of perfumery. Consequently, the analysis of essential oils is still very much of interest, as is illustrated by the excellent series of articles by Lawrence in this journal. We now wish to report a number of products containing small (three-, four-, and five-membered) rings, most of which are found for the first time in essential oils. These products were isolated by chemical group separation, liquid and gas chromatography, whereupon the structures were determined by mass, infrared and NMR spectroscopy. All structures were confirmed by synthesis. The essential oils used were obtained from regular commercial sources.

Investigating New Essential Oils: Rationale, Results and Limitations
Research in new essential oils may provide benefits (missing aroma notes, new sources of isolates, new chiral compounds), but it must reassert its originality and vigor and it must recognize the constraints of economics and regulations.

Parameter test distillations for the superficial essential oils
Every effort was made to ensure that the herb used in the three 1975 distillations was a similar as possible. The same applied to the 1976 season's tests. Nonetheless, the smaller charges consistently return smaller yields of oil per kilo. This is due to an orderly phenomenon that could be discussed on another occasion.
