The anti-bacterial action of essential oils may be their most studied effect, in-part because these are simple experiments to perform. Place a piece of filter paper saturated with an essential oil in the center of a petri dish and watch the growth, or lack of, bacteria around the paper. The larger the area where bacteria do not grow, the stronger the action of that particular essential oil inhibiting that particular strain of microbe. This test, known as an Aromatogram, was popularized by French scientist Paul Belaiche. Through extensive research, large tables of data now allow aromatherapists to quickly find the most efficacious oils once the infecting species of bacteria is known. But you don't have to be a scientist to make use of this information - there are many simple, effective means for using essential remedies for yourself and your family and children as part of a holistic natural health program for your household.

It turns out that nature has been doing a remarkable job of therapeutic blending of essential oils as antiseptics. Plants have evolved these volatile chemical mixtures called essential oils in-part as defense mechanisms against bacteria, viruses and fungi. The antiseptic properties of the oils provide the plant with protection from disease and microscopic invaders. We have significant advantages in using oils for our own microbial defense as humans: The defense mechanisms of plants have been evolving throughout history; these mechanisms are up-to-date with the evolution of the microbes being defended against. Combinations of chemical constituents found in essential oils have been shown in laboratory studies to be some of the most potent antibacterial agents available today.

It is important to consider your application for the safest and most effective result. Applying an Oregano formulation may be the best solution for a case of nail fungus, yet a recipe containing this oil is much too intense for use on soft tissue of any kind, particularly for children and those with sensitive skin. You can even easily mix an antiseptic with a soothing/pain relieving oil to improve the overall effectiveness. Here are a few well-regarded oils for home use, and some methods of application: Tea Tree, Lavender, Oregano, Geranium, and Lemon.

Tea Tree (Melaleuca alternifola) is known throughout the world for its protective properties against infections, and may be the hands-down most popular antiseptic essential oil. The leaves have been used for centuries to heal wounds and skin infections, and with ten times the antiseptic power of phenol (a benchmark chemical used in studying antimicrobial action) Tea Tree is a must for every natural first aid kit. One of the safest and most effective ways of controlling minor infections is the immediate intervention action of Tea Tree. For minor ears, nose, throat, respiratory and general skin infections, Tea Tree essential oil will give quick healing support. Tea tree's tolerability allows it to be used for longer periods of time without the slightest irritation. A drop on a Band-Aid can keep the reddening indication of infection from children's cuts and scrapes, and when combined with Lavender, makes a soothing rendition of Grandma's healing tincture.

Often called 'medicine chest in a bottle' Lavender is the most versatile aromatic oil in use today. An antiseptic, anti-inflammatory, and anxiolytic, Lavender is helpful in the healing of small burns, cuts and insect bites. The cooling aroma disperses heat and inflammation and brings relief from pain, spasms, and general unrest. With its calming and balancing properties, Lavender is very supportive of deep sleep; as noted in 'Clinical Aromatherapy', studies indicate that the aroma of Lavender enabled better rest than common sleeping pills with no side effects. Interestingly, Lavender imparts this action in healing wounds as well. For healing unbroken skin such as burns, apply Lavender 'neat' to the wound several times a day; insect bites also get a 'neat' treatment. For cuts and scrapes, keep a 50/50 blend of Lavender and Tea Tree on hand for the best all-purpose antiseptic, anti-inflammatory and pain relieving solution.

While the Tea Tree and Lavender blend gives us a formula for regular use, Oregano is the all-time heavy-hitter of essential oils for antimicrobial action. Oregano is serious medicine; it has been the subject of many successful scientific evaluations. Interest in the oil's efficacy growing in amongst the world's medical practitioners as infectious microbes become more and more resistant to synthetic antibiotics. Pure oil of Oregano is exceptionally strong - too strong for topical application except in the most stubborn cases, and then only with careful attention. Oregano holds the most promise as a systemic antimicrobial; Oregano oil can be found in enteric-coated (for targeting parasites and bacteria in the intestines) and regular capsules for support of the immune system during illness. Consult a qualified medical practitioner for dosage recommendations.

With a softer aroma and gentle effect on skin, Geranium is versatile choice for frequent use. Harmonizing and balancing, Geranium essential oil has the quality of equalizing hormonal and emotional extremes. These properties extends to the skin, where it creates balance between oily and dry states; Geranium helps to cleanse the skin while restoring balance, tone, and suppleness (experiment with your skin care formulas at concentrations between one and three percent of your base mixture). A non-drying, antiseptic, anti-inflammatory, astringent, and general tonic, Geranium is traditionally indicated as a remedy for acne, dermatitis, eczema, and weeping wounds. The 'asperum' species is generally considered the most potent Geranium for its antimicrobial action, with a wonderful sweet and herbaceous aroma.

Lemon essential oil is a powerful antiseptic and bactericide that performs many tasks around the house, as well as for your health. Lemon has a tonic action on the lymphatic system and a stimulating action on the digestive system, additionally providing relief from insect bites and tension headaches. Use this pleasant antimicrobial blend with confidence to clean counter tops, windows, and door handles: 2 drops each of Lemon, Pine, and Eucalyptus Radiata essential oils in 4 ounces of distilled or spring water (distilled water dries without leaving haze from mineral deposits). Keep a spray bottle of this solution handy for your day-to-day cleaning.

These are but a sampling of the antiseptic and antimicrobial essential oils available. They are easy to use, and offer a excellent means of bringing natural medicines and cleaners into your life. Many oils have specific action against certain microbes; if you or a friend or loved one needs more directed treatment, seek the advice of a licensed or degreed natural health professional, and consult a doctor to ensure the safety of any complimentary essential oil application. The acceptance of essential oils as valid medicines continues to grow. If you're new to the field, dive in with some of the suggestions here - you're sure to enjoy these great gifts of nature.
