Essential oils as Natural Antimicrobial Agents

The use of essential oils as natural antimicrobial compounds has attracted growing interest in recent times. Antimicrobial agents destroy the airborne microorganisms which are typically the source of unpleasant odours. The effective antimicrobial action of various essential oils and their discrete components on different species of microorganisms, such as Escherichia coli, Lactobacillus delbrueckii and Saccharomyces cerevisiae has been previously observed and reported.[1]

The measurable antimicrobial activity of essential oils can be increased by the efficient encapsulation of the oil in a solubilizing carrier. This encapsulation increases the equilibrium concentration of essential oils in the aqueous phase, and the antimicrobial activity has been found to increase with increased essential oil concentration.

In general, if a microbial disinfection action is desired, the best option appears to be the use of a delivery system formulated with an emulsifier with high affinity with the essential oil components. This enables the solubilisation of the component molecules in aqueous phase at a high concentration, preferably higher than the water solubility.

Natural sugar eglucose estersters obtained from renewable raw materials of vegetable origin have proven to be very effective essential oils emulsifiers. These non-ionic solubilisers consist of fatty acid molecules as a lipophilic group with a glucose molecule attached as a hydrophilic group. The requisite antimicrobial compounds are immediately available on emulsification, and antimicrobial activity is evident over short time scales.

Aromatherapy – an ancient art for modern lifestyles

The healing art of aromatherapy uses essential oils, extracted from a range of aromatic plants and trees, to improve mental well-being. These highly aromatic oils have unique therapeutic properties, which can trigger mood changes by association with positive memories.

Literally thousands of years ago, Ancient civilizations used essential oils to cope with a variety of emotional ailments. The Ancient Egyptians had a highly advanced civilization, which recognized the potential of fragrance to uplift the human spirit. They employed aromatics for religious, cosmetic and medicinal purposes – and in particular as a mood altering incense to improve mental well-being.

Now the natural benefits of Aromatherapy are experiencing a renaissance in popularity as this ancient art is being married with modern scientific knowledge to aid in the relief of stress related disorders, such as depression, anxiety and insomnia.

But How?

Our sense of smell is one of the major senses. It responds to the chemical nature of air-borne substances breathed into the nose.

When we inhale an aroma, scent molecules enter the nostrils and pass into the nasal cavity where they dissolve in nasal lining mucosa. This stimulates sensory cells which send signals to the olfactory bulb.

From here, nerve signals travel along the olfactory tract to the cortex, limbic system and hypothalamus in the brain. This is where smells are identified and the body’s response is coordinated.

The limbic area of the brain is primarily involved with our emotions and memories – hence our sense of smell is directly related to how we feel.

Certain aromas can stimulate the limbic system to activate the hypothalamus and pituitary gland, triggering positive emotional responses such as happiness and pleasure – and hence improving our mood.

Aromatherapy can improve our mental state, helping us to cope better with the pressures of everyday modern life and reduce stress levels.

Put simply – Aromatherapy has the power to make us feel good
