Modern evidence for the antiseptic powers of essential oils

Towards the end of the19th century, the first acknowledged research to prove the antiseptic properties of essential oils was that undertaken by Chamberland ( 1887). This was followed early in the 20th century by Cavel's research into the individual effect 35 essential oils on microbiology cultures in sewage. The most effective oil in terms of the quantity required to render inactive 1000 ml of culture was found to be thyme (0.7 ml) . Two other well-knowb oils showing high efficacy were sweet orange ( 1.2 ml, 3rd) and peppermint ( 2.5 ml, 9th). The antiseptic power of several oils now been proved to be many times greater than that of phenol. Certain essential oils have also been shown to be effective against different bacteria, e.g. lemon, which is one of best in its antiseptic and bactericidal properties, neutralizing both the typhus bacillus and staphylococcus aureus in a matter of minutes. Cinnamon kills the typhus bacillus even when diluted to 1 part in 300.

Historical use of essential oils

Plants ad their extracts have been used since time immemorial to relieve pain, aid healing, kill bacteria and thus revitalize and maintain good health. Many books have now been written on aromatherapy, its history usually being included in more or less detail. Suffice it to say here that, although the word itself was not coined until this century, the distilled extracts from plants - the essential oils - have been employed by humankind for countless years in religious rites, perfumery and hygiene. Cedar wood oil, know to have been used by the Egyptians for embalming and for hygienic purposes 5000 years ago, was probably the first 'distilled' oil to have been produced although the process used is open to speculation. Both the lavender plant and its essential oil were used by the abbess Hildegard of Bingen as early as the 12th century, and by the 15th century it is thought that essential oils of turpentine , cinnamon, frankincense , juniper, rose and sage were also known and used in perfumes and medicines by the beginning of the 17th century.

How the brain process odor ?

Odor are the effect of volatile molecules that float through the air , rushing through our nosttrils as we inhale. There are three stages in the process of smelling. Fragrance begins with the reception of odor molecules, which as they are inhaled, bind to the olfactory epithelium ( receptor cells that contain, in all, some 20 million nerve ending ). Odor transmission occurs when a message is fired to the right and left olfactory bulbs, located above and behind the nose at the base of the brain, each about the size and shape of the small Lima bean. At this point a variety of cells and neurons interpret, amplify and transmit the message to the limbic system.
