A report entitled “Prepubertal Gynecomastia Linked to Lavender and Tea Tree Oils” appeared in the New England Journal of Medicine (Henley et al. 2007). The authors concluded that “repeated topical exposure to lavender and tea tree oils probably caused prepubertal gynecomastia in these boys.” To put the context of this paper into perspective it is worthwhile reviewing some information pertinent to this report.

The hypothesis of olfactory receptors as metalloproteins and the future of odorant design. In his recent volume, The Secret of Scent: Adventures in Perfume and the Science of Smell, Luca Turin describes his passion for perfume and his pursuit of olfactive mysteries. Turin re-broached the vibrational theory of olfaction and proposed a transduction mechanism of primary olfactory reception.

IFF developed an interest in aromatherapy in the early 1980s as a potential means for imparting a stress-reducing benefit to fragrance. Aromatherapy is an age-old practice of applying the healing benefits of certain aromatic essential oils. In the traditions of aromatherapy, specific essential oils are stress reducing, whereas others are energizing, and still others can have either effect, depending on the user's state of mind/body interaction. We reasoned that the best way to study the stress-reducing properities of fragrance would be to investigate their physiological effects.

New materials and emerging applications. Physiological cooling agents act in a number of ways. In a flavor or fragrance they can be the first impact, leaving a cool sensation on the palate or skin prior to the main aroma being imparted.

Actively fermenting baker’s yeast (Saccharomyces cerevisiae) not only converts aliphatic aldehydes to the corresponding alcohols, but also may reduce certain carbon-carbon double bonds in the same molecule. Furthermore, an in situ acyloin condensation reaction occurs; this bioconversion reaction gives rise to relatively good yields of unsaturated 2,3-diols, which have two carbon atoms more than the corresponding aliphatic aldehyde used as substrate. Baker’s yeast has been used as a reagent in organic synthesis since the beginning of the 20th century, when fundamental studies were initiated on the mechanism of formation of fusel alcohols from the corresponding l-amino acids during the formation of ethanol.
