Originally cultivated for lamp fuel, lubrication and dietary fat, olives are an old favorite. After centuries of discovery from trial and error, uses for olive oil began to emerge in medical and cosmeceutical home remedies. A naturally occurring chemical found in extra virgin olive oil has been found to exhibit non-steroidal anti-inflammatory properties similar to ibuprofen, according to Gary Beauchamp, Ph.D., director and president, Monell Chemical Senses Center.

Pruritus or itching is an unpleasant sensation that provokes a desire to scratch. Many factors such as chemical, mechanical, thermal and electrical stimuli can elicit the itch sensation. Mediators of itch presumably directly act on nerve fibers or lead to a nerve stimulation cascade whose final common pathway is interpreted in the central nervous system as itching. Putative receptors for itching are C-fibers with exceptionally low conduction velocities and insensitivity to mechanical stimuli. Histamine, the proto-typical chemical mediator of itch, which is released during mast cell degranulation and mediates its effects in the skin via H1 receptor, is the best-known experimental pruritogen.

This review of literature suggests that crosstalk between the stratum corneum and nerve fibers in the epidermis is the process by which itch is transmitted to the central nervous system. A rationale is presented for using moisturizers to reduce itch.

A new phospholipid polymer has been developed for various applications, including cosmetics. In this report, the authors evaluate the polymer's ability to reduce several indicators of surfactant-irritated skin. They also demonstrate the polymer's potential for increasing the lasting time of perfumes.
